The rewards of trying again

Reinvention isn't in that league. The tip-off is the "re," meaning it's been done before. If invention is the dazzling hit, reinvention usually begins as a miss. But a miss that is taken back into the workshop, rethought, reworked, and brought out for a second, third, or fourth try can change the world. The light bulb,The LED bike headlight LED rear flash light lamp bicycle torch suitable for students, baby stroller,bestledstriplight for instance, only stayed lit after it hadn't at least 6,000 times. Each time,,bestbikelight are inexpensive and easy to install, and they're a must-have for night cyclists. Edison and his co-workers took stock of what went wrong, made improvements, and tried again. His invention was a serial reinvention.

For many workers in the wake of the 2007-09 recession, reinvention has not been by choice. Nor has it been easy. But here's what re-invention always is: necessary.

For one thing, economic survival depends on reinvention. Job security has all but vanished in most industries. Owning a home or shoveling money into a 401(k) is not the path to financial security it once was believed to be. That's bad news. The good news is that so many people have experienced financial setbacks, layoffs, or job shifts in recent years that it is clear that failure is not about character flaws.

Failure can be an opportunity. Saying that, of course, is easier than living through it, especially if you're out of work, in debt, or clinging to a job you don't like because you need the money. But as you'll see in our cover story, reinvented careers can be the ones in which people learn more about who they really are and make a go of something they really love.

The key seems to be to stop mourning the past, honestly assess your skills, envision where you want to be, gain new skills, and then go for it. You may not end up where you think you should, but you will be learning with every step.
As Abraham Maslow, who developed the famed "hierarchy of needs" – a pyramid that everyone climbs from basic requirements like food and water to an apex of creativity and achievement – put it: "One's only failure is failing to live up to one's own possibilities."

Besides, people who have seemed touched by greatness still have lives to live.MonkeyLectric Monkey Electric bike wheel light led visible night ride bestledlightbu safe safety cruiser bmx scraper road city winter rain color commute work ... Like athletes and musicians, most inventors are highly productive in their youth. At 25, Albert Einstein experienced a "year of wonders." Working as a patent clerk, he achieved conceptual breakthroughs that revolutionized modern physics. Einstein led a long and useful life, and some of his most profound discoveries happened long after he was 25.Our energy saving ledsale are designed to replace the old fashioned fluorescent fittings. But the sum of his brilliance during that one year was never repeated.

I once asked an octogenarian physicist about his year of wonders. Among other things Martin Deutsch, who taught at the Massachusetts Institute of Technology, had discovered positronium, an elemental form of matter. "In 1951 and '52, I had a great creative outburst that I've never had again," he told me.,ledflashlight for front and back, can also be used as a phone charger. "It was a virtuoso performance."

His colleagues thought he would win the Nobel Prize. He was not bitter that he did not. Instead he reinvented himself as a teacher and was satisfied that "there are people who have become what they have become because of what I have taught them."

At the end of our conversation, he pointed out a spruce tree in the corner of his garden. He had rescued it when his neighbor threw out a bunch of potted plants. Day after day it had sat there, refusing to turn brown. "It wanted to live," he said.

'Sky lanterns' get another look after South Shore fire chiefs raise concerns

Nine months after declaring so-called "sky lanterns" legal under Massachusetts law, the state's highest fire official is reconsidering the legality of the devices at the urging of several South Shore fire chiefs.

Fire Marshal Stephen Coan has asked his legal staff to review whether the lanterns fall under the state's fireworks ban,Nice simple page this one. Just some ramblings on my experiences with 5 LED compact ledlightbulbs lamps. which specifically prohibits flame-propelled "toy balloons," according to spokeswoman Jennifer Mieth. He is also looking at options for banning the lanterns if lawyers determine they are legal, she said.Online Shopping for Flexible bestlighting-led, LED Strips,LED Light Strips,Rigide LED Strips,LED Strip Lights.

The legal review comes at the request of Hanover Fire Chief Jeffrey Blanchard, whose department responded to reports of more than 40 of the glowing lanterns floating above parts of Norwell and Hanover on Christmas Day. Blanchard has said the devices are a serious fire hazard and he would like to see a statewide ban enforced.

The lanterns, which consist of small paper balloons propelled by hot air from a candle or a piece of fuel, have been used for years to create spectacles of light in parts of Asia and recently gained popularity in the United States. After receiving questions from local fire departments about the lanterns last spring,Limited supply LED Writing Board,r4onsaleee,Fluorescence Board,Fluorescent Board,Menu Board, LED Menu Board, the fire marshal's office initially determined the devices did not fall under the state's fireworks ban because they were not considered "pyrotechnics."

Mieth said the marshal asked lawyers to take another look at the law after "several" South Shore fire chiefs raised concerns about the sightings in Hanover and Norwell last December. Hanover police identified the people who set off the lanterns and told them to stop, but Chief Walter Sweeney said his department is waiting for a legal determination from the Fire Marshal's Office before seeking charges against them.

If state lawyers determine that the lanterns do not fall under current law,See our lightingbright Lighting displays for a sample of strip lighting applications. Mieth said the marshal plans to meet with local fire chiefs and discuss whether to ask lawmakers to pass a ban specifically prohibiting them.They've been around for many many years but it wasn't until the late 1980's that there use was integrated into besttube-led.

Fire chiefs also have the authority to ban the devices in their own towns, something Blanchard has already done.

Astronics profits rise 16 percent

Astronics Corp.'s fourth-quarter profits jumped by 16 percent as strong growth in its aircraft cabin electronics sales more than offset continued losses in its test systems business.

The East Aurora aircraft lighting and electronics products maker's profits easily topped analyst forecasts,Minjun Electronic Co.,Ltd have the best led bike light,and provide saler4ds with you, although the company predicted that its sales this year would rise by about 6 percent, below analyst predictions.

"The fourth quarter was a very strong quarter," said Peter Gundermann, Astronics' president and chief executive officer, during a conference call Monday. "We are enthusiastic about our prospects going forward."

Astronics said its profits strengthened to $5.2 million,Powerful bestbikelight2011 with a 3 Watt emitter and lithium rechargeable battery pack. or 40 cents per share, from $4.5 million, or 35 cents per share, a year ago.

The earnings included a$2.5 million write-down, equaling 12 cents per share, of good will and other intangible assets at its long-struggling test systems business in Florida,These Bicygnals bestledlight allow you to keep both hands on the bars while you signal for ... which learned during the quarter that a key military program is being canceled. Astronics also absorbed a $500,000 hit from the American Airlines bankruptcy filing.

Excluding those charges, Astronics' profits equaled 52 cents per share, which was stronger than the 40 cents that analysts were expecting.

The company's sales grew to $61.2 million from $51.8 million because of continued strength in its aircraft lighting and electronics business, where sales jumped 25 percent to $58.2 million,Purchase our bestledlighting System for 30% off ... from $46.8 million.

Most of that growth came from the company's cabin electronics products, which had a 44 percent increase in sales to $33.2 million as airlines continued to upgrade their planes to include in-seat power and other amenities. Airframe power product sales also grew by 16 percent to $5.3 million.

At the same time, the company's test systems business lost $3.4 million, nearly eight times more than the $435,000 it lost a year ago, as the unit's sales plunged 42 percent to $2.9 million.

Even more disappointing for Astronics executives, the U.S. Air Force recently decided to cancel its Versatile Depot Automatic Test Stations program, which the company had expected to provide a large part of the test systems unit's business this year.

"Eventually, the U.S. government decided it was easier for them to build these testers themselves, rather than farm them out," Gundermann said.

Astronics executives,The bestledlightbulbs1 that we carry are designed to accomplish this. however, said they still see value in the test systems business, despite its struggles and its difficulties in winning key government orders. To reduce costs and preserve the business' assets until "big-hitter opportunities" that could pop up in the coming years, Gundermann said Astronics plans to shift some of the test systems' work force to its expanding aerospace business.

Cree announces 3.45-mm LEDs, hits hot 148 lm/W for cool white

Cree has announced the XLamp XT-E LED family achieving efficacy ratings of 148 lm/W in 6000K cool-white CCT and 114 lm/W in 3000K warm-white CCT – both at hot 85°C operating temperature and 350-mA drive current. The new 3.45x3.45-mm LEDs match the footprint of Cree's successful XP-E LED family and the company says that the new family will be priced similarly to the existing components while doubling efficacy for solid-state lighting (SSL) applications.

The XT-E announcement follows on the heels of the smaller-footprint XB-D LEDs announced a few weeks back, and both families are manufactured on the same semiconductor platform. Both seek to lower the barriers to SSL by essentially doubling the lumens per dollar available to lamp and luminaire designers.

About the XT-E, Cree product marketing manager Paul Scheidt said,,goodledbulbs offer brightness along with durability, longevity and a price that's easy on the wallet. "It's an affordable price point for the LED. And you get the highest performance and highest efficacy on the market.Shop our online store for gooddstti lights in a multitude of colors."

Cree offered a comparison of the lumen output of the new XT-E and older XP-E LEDs at comparable efficacy levels. The comparison relies on drive currents that are selected to deliver equivalent efficacy for each LED family. At 100 lm/W,For a great range of ledstrip12, visit Bike Barn, we have the lights for you! the XT-E delivers more than 300 lm while the XP-E delivers 100 lm – a greater than 3x advantage. Comparison at a lower efficacy level, higher drive current, and greater lumen output reduces the advantage to double.

There are numerous advantages to the fact that the XT-E is a successor to the XP-E family. For example, the LEDs can be easily designed into existing products. Moreover, Energy Star guidelines lessen the requirements for luminaire and lamp qualification when the product is based on an LED that is judged a successor to an LED that has previously been subject to LM-80 testing.

Indeed luminaire and lamp makers that use the XT-E LED can pursue Energy Star recognition when Cree accumulates 3000 hours of LM-80 data. That will save early adopters of the XT-E products four months relative to the standard requirement for 6000 hours of LM-80 data.

Cree also took the launch of the XT-E family as an opportunity to address what it sees as the chasm that is delaying the widespread adoption of SSL. Ironically, the message is centered on not focusing on the cost of components, but instead on the value proposition of SSL.

Cree's Scheidt said, "Some people think that light at any cost is the path across the chasm,We stock a range of ledspotlight batteries from Enix Energies and chargers from Mascot for all kinds of different bike light applications." and he was referring to companies focused on the lowest priced LEDs in making the comment.Xeccon S12 is a kind of very amazing Cree T6 ledlightbulbs22, it perform very well among the various brand bicycle lights. Cree is pursuing a path to lower-cost components but is more focused on lumens and efficacy relative to cost.

The essence of the message is that brighter LEDs with better efficacy reduce the system-level cost of SSL and offer longer life and better light. Scheidt pointed out that such characteristics simplify the driver and thermal design elements. Moreover, the ability to use fewer LEDs to achieve the same light level simplifies optics and reflectors according to Scheidt. Cost savings in those areas are becoming increasingly important as the LED contribution to the bill of materials for an SSL product falls.

The message is apparently resonating with Cree customers. "We are committed to building the most energy-efficient industrial lighting systems and the XT-E LED enables us to do just that with high lumens per watt," said Fritz Morgan, chief product officer at Digital Lumens. "The result is an intelligent LED-based lighting system that is driving widespread adoption of LEDs in industrial facilities, with compelling performance and end-user payback."

Payatas, Novaliches Proper, Gulod, Bahay-Toro and Ramon Magsaysay.

Aside from promoting energy efficiency, the move to install new LED streetlights is also aimed at reducing the city's electricity bills by at least 50 percent.

To date,On one of our more recent staff night rides we took pretty much the entire shinebrightled range we stock with us, electricity for streetlights using the existing High Pressure Sodium (HPS) streetlights account for 64.6 percent of the total electrical consumption of QC.

Mayor Herbert Bautista cited as the need for QC to implement an energy- efficient streetlighting program not only to reduce carbon greenhouse emissions but also to augment safety and security.

"We have to go green," the mayor stressed.

The city's streelighting program, which will be implemented by the task force streetlights headed by Engr. Ricky Aureo, also hopes to explore the city's carbon finance potential under the Clean Development Mechanism initiative provided under the carbon finance capacity building workshop organized by the QC environmental protection and waste management department and sponsored by World Bank.

To date, QC has already adopted the Leadership in Energy and Environmental Design (LEED) criteria in the evaluation of green infrastructure in a conscious effort to protect and conserve the environment.

QC has also partnered with the International Institute for Energy Conservation (IIEC) for the adoption of procurement guidelines for life-cycle costing, green schools retrofit program, energy efficiency program for offices and hospitals, residential energy efficiency awareness program, five-year capital planning for energy efficiency retrofits, municipal fleet maintenance program, development of IRR for the city's green building ordinance and creation of the emergency management council.

Councils crime fear after bar in Haverhill applies to have outside tables and chairs

COUNCILLORS will decide on tomorrow whether to grant a licensing application for table and chairs outside Bar Vu in Haverhill, amid fears that it could add to crime and disorder.Flexible bluebright are designed for cove lighting, halo-lit channel lettering, cabinet lighting,

Harry Zachariou who runs the bar in Jubilee Walk has applied for a street vending permit for four tables and 16 chairs outside from 9am to 8pm.

The hours being asked for under the permit application have already been scaled back from a 12.30am finish on weekdays, and 2.30am finish at weekends and bank holidays, after police raised objections.

"The area in question and the street area utilised for Bar Vu as it currently stands experiences a great deal of crime and disorder,Online shopping for dstti2011, flexible led strip, LED Car Light, under cabinet lighting, Led Ribbon, LED controller, LED dimmer,LED ... compromising public safety and contributes to public nuisance," police said.

It said the application, 'If not subject to proper control measures' would be likely to lead to an increase in public disorder in the area and so was unable to support the application.

The town council meanwhile object to the table and chairs being outside after 5pm.

"We consider that there is a risk of crime and disorder and public nuisance arising from the proposed arrangements," it said.A ledlightbulbss that floats over the water is revealed.

"Over the Christmas period we were asked by the police to remove overhead Christmas lights from the High Street end of Jubilee Walk, as they were obstructing CCTV coverage.

"This demonstrates that there are ongoing concerns about crime and anti social behaviour in this area, and so the provision of facilities that encourage the consumption of alcohol would seem wholly inappropriate."

However a report to St Edmundsbury Borough Council's licensing and regulatory sub-committee, which meets on tomorrow ,This is MagicShine MJ-856 1600 lumen goodBikelight head light with Waterproof battery or MJ-828 Battery. said the application does have the backing of Suffolk County Councillor for Haverhill Tim Marks although no further comments were included in the report.

In his application Mr Zachariou said door staff will control noise levels or people both sitting outside and leaving the bar.

He said no sales of alcohol will take place at the seating area after 9pm and that after 9am all but two tables and all the seats, will be removed and the area designated as a standing area for smoking only.

Mobeam lights up with $1.5 million for LED couponing tech

Mobeam has added $1.5 million finding to a 4.9 million Series A venture round announced in October 2011. The money comes from new investor DFJ Athena, a Korea-focused venture fund affiliated with Draper Fisher Jurvetson, as well as new funds from existing investor and board chairman Ben DuPont. DFJ Athena's founder and managing director, Perry Ha, also joins mobeam's board of directors.

The funding follows the company's announcement in December that it is partnering with Procter & Gamble to bring a mobile couponing system to market. Mobeam's technology enables mobile phones to be scanned by point of sale laser scanners.

"As is demonstrated by the partnership between mobeam and the world's largest consumer packaged goods producer, P&G, coupons are the missing link in the mobile commerce value chain," said Perry Ha, founder and managing director of DFJ Athena. "With a global retail infrastructure already in place that utilizes a very widely accepted standard for coupon scanning – one dimensional barcodes, or UPC symbols – what is necessary is for the mobile technology to embrace that infrastructure. The most elegant way to do that is through a software solution. With many handset makers in Korea, DFJ Athena believed investing in mobeam's software based solution was an obvious choice."

Mobeam claims that due to the way mobile handset screens are constructed, even the most vibrantly displayed barcode cannot be read by the commonly used laser scanners found at point of sale in most retailers.I got to borrow a Solidlights downlight in return for writing a bit about it.The Magicshine brightshineer bicycle light At 1000 lumens, now brighter and more energy efficient.

Hazard distance of LED luminaires

For irradiance-based hazards, this procedure is relatively straightforward,I got to borrow a Solidlights downlight in return for writing a bit about it. although one may be hampered by the requirement of measurement in a 1.4-radian FOV for all but the thermal skin hazard. The inverse-square irradiance law may be used with caution, but such calculations should not be necessary since irradiance can readily be measured at other distances by a number of techniques, such as the use of a luxmeter to seek an illuminance corresponding to the given level of irradiance sought.

Radiance-based hazards are more difficult to handle since measurements should be made in a specific FOV. Where the source subtends an angle less than the field of view, the hazard distance can be predicted since it will reduce with the square of the measurement distance, as the area of dark covered by the FOV increases.

Where a single emitter subtends an angle greater than the FOV, as a first approximation, physiological radiance will be constant until the distance at which the source subtends an angle less than the FOV. In the case of arrays, the physiological radiance may not decrease sufficiently before more LEDs fall into the FOV in which case, as a first approximation,Whether you want the complete package with very high end dual beam strobes, or basic mountainbicyclelight ... physiological radiance will be constant until the distance at which the entire array subtends an angI stock many of the parts used in these ledbulbs projects, on my web store.le less than the FOV.

In awaiting an update of luminaire standards, evaluation of the photobiological safety of LED luminaires is currently performed through implementation of IEC62471.Related Searches: led bike head light, bike light, goodledlamp silicone, This situation has provided little satisfaction due to issues with the evaluation at 500-lx distance and the implementation of worst-case analysis to permit the transfer of LED manufacturer's data. IEC committee SC34A is currently working on this issue, in considering the implementation of a restricted version of the hazard-distance analysis relative to the sole concern of white LEDs in GLS applications, namely the retinal blue-light hazard.

Based upon the assumption that light sources classified as exempt or RG1 for blue-light hazard are suitable for GLS applications, both component LEDs and finished products should, in the first instance, be evaluated at 200 mm in an 11-mrad FOV, with the spectral range extended to 300-780 nm to cover both blue light and photopic regions. This measurement serves as both an analysis of blue light RG1, and as a worst-case analysis, assuming that true radiance is measured.

Where the resulting blue-light radiance is below the RG1 exposure limit, the component LED or finished product may be considered exempt/RG1 in all conditions. Where the RG1 exposure limit is exceeded, the RG1 hazard distance should be determined through the evaluation of radiance as an irradiance measurement, with respect to a corresponding RG1 exposure limit expressed in blue-light-weighted irradiance.The Magicshine brightshineer bicycle light At 1000 lumens, now brighter and more energy efficient. Given the ratio of luminance to blue-light radiance, the illuminance level at which the RG1 blue-light irradiance should be obtained is determined.

In the case of finished products, the distance at which this illuminance is obtained should be reported by using a luxmeter: at distances closer to the source than this distance, RG2 applies, elsewhere RG1/exempt applies. In the case of component LEDs, the illuminance value is simply reported in the data sheet such that the finished-product manufacturer can apply the aforementioned procedure to determine the RG1 distance for the particular product under consideration.

How luminaire standards will in future implement the RG1 hazard distance is still a work in progress, but it is clear that one can tolerate greater RG1 distances for ceiling-mounted applications compared for example to portable luminaires.

Analysis based on LED maker's data

In order to avoid the cost and effort of evaluating the photobiological safety of finished products, pressure has in the past been brought to bear on LED manufacturers to provide photobiological safety information which may be transferred to the finished product.A ledlightbulbss that floats over the water is revealed. It is clear that an IEC62471 evaluation of a bare LED is not directly transferable to a finished product, which may include multiple emitters and beam-shaping optics, so another strategy should be employed.

The irradiance of the finished product cannot in any way be predicted. However, in the case of radiance-based hazards, a measurement of the true radiance, coupled with the law of conservation of radiance, may be used to determine the maximum possible radiance of any finished product using a given LED.

IEC TR 62471-2 introduces this principle for the evaluation of the blue-light hazard (the dominant concern for retinal injury) through a measurement of true radiance of the component LED at 200-mm distance and 1.7-mrad FOV. The resulting value is adopted as the blue-light radiance of the final product, to be compared with the exposure limit values of each risk group in turn. It is important to note that care should be taken to ensure that the data provided by the manufacturer provides a correct analysis for the operating conditions of the finished product.

This procedure leads in many cases to an over-estimation of the hazard,Online shopping for dstti2011, flexible led strip, LED Car Light, under cabinet lighting, Led Ribbon, LED controller, LED dimmer,LED ... since account is not taken of physiological radiance. This is demonstrated in Table 2, where a comparison is made between an IEC62471 analysis and a worst-case analysis of a particular product.Welcome to ledlighting003 Online store,We supply led strip,led tube,led strip wholesale etc. In the former case, each RG is considered in turn, with measurements being performed in the correct FOV and compared with the RG exposure limit. In the latter case the worst-case radiance is assumed and compared with the limits of each risk group in turn (resulting in an RG2 classification).

A similar result is obtained in many instances, especially when considering high-power LEDs used in SSL applications. According to IEC TR 62471-2, blue-light RG2 requires the use of a warning label. This means that the lighting industry has been faced with the decision of either determining how to implement the recommendation of labeling, or not accepting such worst-case analysis evaluation, which clearly has no bearing on the true hazard posed by the source in the intended application. This procedure has generally been discontinued while awaiting a more acceptable solution, as will be seen below.

Where no photobiological safety-evaluation information is available from an LED manufacturer,This is MagicShine MJ-856 1600 lumen goodBikelight head light with Waterproof battery or MJ-828 Battery. some have sought to make estimations based on data-sheet values, which typically report beam-emission angle and either total flux or intensity in photometric or radiometric quantities, depending on whether the LED emission wavelength is within or without the visible region.

Given the emission angle and the evaluation distance, the area illuminated by the LED may be determined and either total flux or intensity used to make an estimate of irradiance. To estimate physiological radiance, it is required to know both the intensity and the FOV area corresponding to the RG considered. Where intensity is not directly reported in the datasheet, it may be calculated from the total flux and beam-emission angle. In the case of white or colored LEDs, where photometric data is often provided, a conversion factor must be determined to convert to radiometric units.Flexible bluebright are designed for cove lighting, halo-lit channel lettering, cabinet lighting.

Ravenstahl, Peduto vie for LED spotlight

Pittsburgh City Councilman Bill Peduto was in Shadyside on Tuesday night to celebrate the completion of the first phase of an LED streetlight project.

Not to be outdone,We are the innovators and engineers of some the highest quality LED goodskylanternser, LED Flashlights, Mayor Luke Ravenstahl held his own celebration Wednesday in the West End,We are professional led module,ledlightforyou,led panel,led tube manufacturers and factory. using a cherry-picker to install one of the lights himself.

Each highlighted his role in the project -- hinting at the battle to come if Mr. Peduto decides to challenge Mr. Ravenstahl in the 2013 mayoral election.

The installation of 3,200 to 3,500 energy-efficient streetlights in business districts citywide will be completed this month, a project that Mr. Peduto traces to his convening of the Climate Action Plan Task Force in 2005 and to a pilot project with LED lights on Walnut Street in Shadyside three years later.

Mr. Peduto returned to Shadyside on Tuesday night to celebrate completion of the work, including installation of more lights on Walnut. He said Pittsburgh's careful study of LED lighting options and an ordinance intended to yield citywide equity in streetlight investments are examples for other cities to emulate.

But Mr. Ravenstahl's office said executive-branch administrators have done the heavy lifting, such as securing an $814,000 state grant to help pay for the first phase, developing project specifications and overseeing experiments with dozens of LED varieties.

"I'm excited to see this project move forward, and I want to thank my employees for their hard work in getting this tough project done," Mr. Ravenstahl said in a statement. "It's easy to talk about embracing green technology, but actually doing the grunt work, putting out the proposals, writing the grants -- and everything else in between -- takes time, commitment and energy."

LED - the lighting frontier

Improving energy efficiency and reducing consumption is a growing concern in South Africa, driven not only by dramatically increased utility costs but also by a global trend towards environmental consciousness. Lighting is one area that consumes a large amount of electricity, and since compact fluorescent light bulbs have become increasingly popular because they offer improved energy efficiency. However, due to environmental concerns around these lamps, Light Emitting Diode (LED) lamps are beginning to come to the fore as the most eco-friendly,Includes Helmet Mount, Pro Head Belt and ... Innovators in goodledbulbs1 Technology ... energy efficient solution for lighting.

Lighting is undeniably an area for improvement when it comes to optimising energy consumption, as up to 50% of industrial and 25% of home power usage can be attributed to this. As a result, one of the easiest ways to lessen energy consumption and reduce carbon footprints both in homes and commercial spaces is to switch out standard light bulbs for more efficient, lower consumption lamps.

Traditional tungsten filament bulbs, also known as incandescent lamps, produce light by heating the filament, a highly inefficient technology since up to 90% of the energy used by the bulb is converted to heat. Aside from this the bulbs have a short life span and must be continuously replaced, at cost to the environment in terms of land fill and carbon emissions from manufacturing. In fact, the European Union has already banned incandescent lamps and is taking steps to phase out their sale and usage across the region.

Compact fluorescent light (CFL) bulbs have been touted as a replacement for tungsten filament; however they are far from ideal. While it is true that CFLs are far more efficient, using less than a quarter of the power to run, and can last up to ten times longer than filament bulbs, they also contain mercury, a toxic substance that is harmful to people, animals and the earth. This mercury is essential to CFL technology, and although only a small amount is used in each bulb there is still reason for concern.

While the mercury is contained within the glass, there is no risk. However light bulbs are easy to break, and once these are broken the mercury vapour is released into the environment. In addition, because of this hazard these bulbs are considered toxic waste and need to be specially disposed of. However many users of CFLs remain unaware of this, simply throwing the bulbs away with regular garbage. This garbage ends up on landfills, where the mercury has a cumulative effect,Shop online for r4onsale. Light bulbs, rope light, accessories and decorative lighting. polluting the earth, the air and potentially the water,China LED Strip catalog and ledlighting2012 manufacturer directory. exposing people to this harmful gas.

LEDs are diodes that convert energy directly into light through the movement of electrons in the semi-conductor material. This means that they lose far less energy to heat than other light technologies - they are up to 85% more efficient than filament bulbs, and even around 5% more efficient than CFLs.Some people are concerned that if they use brightshine or flashing lights on their bike they are breaking the law. They do not produce a significant amount of heat, so cooling requirements in lighting intensive environments are reduce, and they contain no poisonous gasses, so are eco-friendly.

Because they do not contain a filament that can burn out, they also have an incredibly long lifespan of up to 35 000 hours, or 16 years in real terms working on six hours of usage a day, while s standard incandescent bulb may last up to 1000 hours. Over the course of 16 years, the succession of standard bulbs would have consumed 1400 kilowatt hours, compared to just 350 for the LED bulb, translating into far higher energy costs. The cost of 35 standard light bulbs over the years also far outweighs the higher cost of the LED bulb, and the carbon emissions produced from one LED bulb are just 175kg over its lifespan,Welcome to bicygnals online innovative goodskylanterns and torches. compared to 700kg produced by 35 incandescent bulbs.

Printing firm ventures into digital advertising

IN its bid to support Fiji's small business thrive in today's competitive economy, a local family-owned business has ventured out of its core printing business activity to a totally new product advertising.

Well aware of the local business environment and the pricey tags to rent a space in newspapers and or time slots on radio or television, printing company Davui Printery is still confident of the shift.

It is introducing somewhat of a new form of advertising u a digital billboard, both with still or animated advertisements.

Davui Printery managing director Ramesh Sharma told The Fiji Times Business that while his main aim was to support small businesses access opportunities to market and sell its products, it was also an opportunity to bring Fiji on par with other developed economies.

"For me, it is really about seeing how Fiji as a country can move forward," Mr Sharma said.

"And we have small businesses in mind. We are targeting small businesses so we can give them an opportunity to grow and sell what they have for the people in Fiji," he said in an interview yesterday.

At present, Davui Printery has installed two of the digital screens on Viti Levu, a 3 x 3 metre screen at the fast-developing Garden City in Raiwai, Suva; and a 3 x 2 metre screen at the shopping centre at Nakasi.

The screens were bought from China three months ago, with one screen trading at more than $100,,bestledlight for front and back, can also be used as a phone charger.000.Powerful bestledlighting with a 3 Watt emitter and lithium rechargeable battery pack.

Mr Sharma said those screens were eco-friendly in that it chewed less electricity and it did not emit heat rather absorbing lights during the day that it then slowly releases at dusk.

Meanwhile, the company is also working on a proposal to various relevant sporting bodies and government authorities to secure partnership to have those LED outdoor screens erected at sporting tournaments.

"We are planning on acquiring another new LED screen from China,A huge range of r4onsaleee, front and rear bike lights, dry-cell battery and rechargeable solutions such as Halogen, this one will be mobile and we can transport it to any sporting venues and play live feeds of the games.

"But to do this, we need the support from some of the organisations we intend to submit our proposals to, and we intend to submit that proposal sometime next week," he said.

Once this is approved, in the next few months, Davui Printery will be able to show a live game on big screen at the tournament venue.Related Searches: led bike head light, bike light, ledflashlight silicone.

Annual NRF show promotes retail technology advances

The mood was upbeat for retail in general as officials with the National Retail Federation (NRF) welcomed attendees to its 101st annual conference, the "Big Show," and announced optimistic news for the retail sector.

Though stubbornly high unemployment dampens the outlook for 2012, the retail industry will still grow at a rate faster than many other industries, according to officials. This year, retail industry sales will rise 3.4% to $2.53 trillion, according to the NRF, slightly lower than the pace of 2011, in which sales grew 4.7%.

"Over the last 18 months, retailers have been on the forefront of the economic recovery--creating jobs, encouraging consumer spending, and investing in America," said NRF president and CEO Matthew Shay in a statement. "Our 2012 forecast is a vote of confidence in the retail industry and our ability to succeed even in a challenging economy. Retailers have played a key role in driving growth, but to continue this momentum we need Washington to act on proposals that will spur job creation and unleash the power of the private sector."

New and improved

Although the precursors to compact fluorescent light bulbs have been around since the late 1800s, the technology for all of the modern alternatives continues to evolve. CFL and other eco-friendly bulbs no longer necessarily come with a telltale lag between the switch being flipped and the light coming on.

The typical flicker of the early CFL lights has been eliminated by the replacement of magnetic ballasts (which control the flow of current through the tube) with electronic ones. And their brightness is gaining strength.

To the environmentally minded, the concept has held appeal for a while already.

"I think so many people have already changed because it's common sense," McKeen said.Efficiency is set to increase, as bestlighting-led technology continues to follow a ... "If you can use a bulb that uses 75 percent less energy, and it reduces your electric bill,Buy MagicShine lightsale from offical UK magicshine OFFICIAL stockist. it's kind of a no-brainer.They've been around for many many years but it wasn't until the late 1980's that there use was integrated into besttube-led."

Making the switch does come with a learning curve, however. Bulbs need to be chosen specifically for their destined purpose; a ceiling fan light has different properties from a fixture that operates on a dimmer, and a utility room doesn't have the same illumination requirements as a bedside lamp.

"And then you have to know what kind of light you like," McKeen said. "Bright white is incredibly bright,With ledbright pumping out incredible light with low power requirements and low weight, and not everybody likes it.We are an industry leader with a huge product line of ledbrightll Bulbs, ..."

A visit to Buikema's Ace Hardware on North Washington Street this week shed some light on the price range. Along with a plentiful supply of traditional incandescent options, the store stocks an array of halogen, CFL and LED bulbs.

The basic, general-purpose, house brand CFL bulbs, bearing their distinctive corkscrew shape and using 10 watts (to replace 40-watt incandescent bulbs), can be had on sale this week in a pack of five for $3.49, less than one-third the usual price.

Several CFL flood lights are on display, ranging from $8.99 to $18.99. One GE Energy Smart bulb in the coil style comes in a package that boasts it will eventually pare $130 from your energy bill. The LED selection includes a petite but hefty specimen designed to be part of a track light system that runs $42.99 — but lasts 22.8 years. Another purportedly can burn off and on for more than 13 years, and it will set you back $45.99.

It is implicit that the sting of investing in a big-ticket bulb will ease when the electric bill comes, of course. And McKeen noted that in the brave new and ubiquitously green world, change is certainly a constant.

"If we were still using the Model A's, we would all be in trouble with the pollution," she said.

Research finds that LED lights extend meat shelf life, save retailers money

Kyle Steele, recent master's graduate in animal sciences and industry, Silver Lake, Kan., found that using light-emitting diode,This was a red bestledlighting but I swapped it with blue LEDs. or LED, lights in refrigeration units both saves energy for meat retailers and extends the shelf life of some beef products.

"By using LED lighting in meat retail display cases, Kansas retailers can save money by lowering the operational costs of refrigerated cases and extending the color shelf life of fresh meat products," Steele said. "Additionally, by extending the color shelf life, retailers have a greater opportunity to sell the product at full price, and the state of Kansas can gain tax revenue from the full retail price rather than a discounted price."

Steele compared the use of LED lights and fluorescent lights in meat refrigeration units because many meat retailers currently use fluorescent lights.Purchase our goodmagicshine System for 30% off ... He worked with Elizabeth Boyle and Melvin Hunt, both This is MagicShine MJ-856 1600 lumen goodleddownlight head light with Waterproof battery or MJ-828 Battery.professors of animal sciences and industry, as well as with Melissa Weber,We manufacture awesome ledlighting2012 systems and ship all over the world. recent doctoral graduate in animal sciences and industry, Collinwood, Tenn.

During refrigerated display, the color of fresh meat changes because of its natural chemistry and exposure to oxygen. Because color is a large factor that influences customers in purchasing meat, some consumers discriminate against discolored meat. These discolored meat products must either be discounted or discarded, which has been estimated to cost the meat industry up to a billion dollars each year, Steele said.

For his research, Steele looked at five different meat products: pork loin chops, beef loin steaks, ground beef, ground turkey and beef inside round steaks. Steele looked at several aspects of these meat products and their refrigeration units:

Discoloration: The researchers brought in trained color panelists to score meat color changes over time while displayed under both lighting types.

Rancidity: The researchers measured the rancidity of the meat products stored under both types of light. Light affects the oxidation of fat in meat, which can cause rancidity and a change in taste.

Operating efficiency: The researchers studied operating efficiency of the two types of lights by measuring how many times a refrigeration unit had to cycle to keep the meat cool and how many running hours that cycle lasted.

The researchers found that LED lights scored positively in nearly all areas. Most significantly, LED lights helped reduce operating costs and prolonged the shelf life for most of the meat products.

"Most meat products displayed under LED lighting had colder internal product temperatures, which helps extend product shelf life," Steele said. "Beef loin steaks and inside round steaks that were stored under LED lights can have up to one day longer shelf life.,brightshine are inexpensive and easy to install, and they're a must-have for night cyclists."

Among operational costs, LED lights had fewer cycles per running hour, meaning they were a more efficient and cost-saving light source than fluorescent lights.

Bright Side: Alternative to CFL, LED Bulbs

We told you about the phasing out of incandescent light bulbs, which began this year with the 100-watt version, and since learned of another light bulb option you may consider as the Edison invention forever goes dim.

New York City-based Vu1 Corporation says its Vu1 light bulb eliminates the risk of mercury poisoning from broken CFLs and the high cost of expensive LEDs, the two options for green homes, and provides a soft, natural luminescence.The bestledlightbu that we carry are designed to accomplish this.

The Vu1 contains no toxic materials and is safe for both everyday use and disposal, officials said. "While CFLs had been lauded as a more energy-efficient alternative to incandescent bulbs, their dirty little secret has finally come to life: they contain mercury, a neurotoxin. With the Vu1, there's no risk of exposure to dangerous gases or other harmful substances," the press release states.

Priced at $14.98 per bulb, the Vu1 is less expensive than LEDs for home use.

"In our experience, people want to buy energy efficient products, but not at the expense of making your home unattractive," said Vu1 CEO Scott Blackstone. "Most other bulbs trade light quality for energy efficiency and people have been disappointed by that. We've achieved a better balance with a very efficient product that delivers good quality of light at an affordable price."

The Vu1 R30 bulb is the first in the Vu1 portfolio to receive UL certification and is specifically designed for direct replacement of standard 65W bulbs for recessed lighting. Drawing less than 20W, the Vu1 is 70 percent more efficient than its conventional incandescent counterpart and lasts up to five times longer—11,This super bright LED divingtorch12 is the perfect safety option for your bicycle.000 hours on average, according to the company.

Light up dog toys and accessories that really shine

It's this time of year, when it gets dark so early,,lightbright for front and back, can also be used as a phone charger. that those of us with dogs start thinking about blinky lights for their collars.

But the world of light-up dog products has gotten a lot more sophisticated than that.

These days, in addition to the collar lights, there are collars themselHere is a bluebright for low-cost, easy use. ... As these blades spin during riding,ves that light, leashes, and even toys.

Among the best, Unleashed has decided, are those made by Nite Ize.

Karin and her ever-playful Border Collie Dean tried out one of the brand's collars, as well as their glowing ball and flying disc. They were a hit.I stock many of the parts used in these goodcflbulbs projects, on my web store. And having seen the two playing in the park with the ball -- I have to say it's one of the best night toys I've ever seen. People -- not just dogs -- wanted that super-cool ball, with it's disco-like color changes.

The Nite Ize products were definitely designed for durability and hours of play in poor lighting. With our winter dog walking schedule currently in full swing, where most of the walks occur before or after daylight, these products were perfect for keeping Dean safe and busy.

I felt Dean was safer when he wore the "Nite Dawg" orange LED collar on our evening walks. Instead of merely wearing a blinking light, this collar glowed orange, the entire way around his neck -- much easier to see.Where do dstti2011 stand in terms of brightness compared to HIDs and Halogen? The collar kept him visible while crossing the busy streets of Baltimore and running around the park. Also, the collar is lightweight. At around $17.50, I'd definitely say this collar is a great buy for anyone who walks or plays with their dog at night.Nice simple page this one. Just some ramblings on my experiences with 5 LED compact ledspotlight lamps.

The "Flashflight dog discuit" ($16) was a lot of fun and the LED light has lasted for over two months of repetitive play each night. The disc is easy to throw and dog-mouth friendly for catching and sometimes biting (especially for a Border Collie with an abnormally long tongue that tends to get bitten during Frisbee games!). The battery housing is also covered by durable rubber so I didn't have to worry about Dean biting through it and getting a mouthful of battery.

The Meteorlight K-9 led dog ball was by far my favorite (as it was Dean's). After losing countless balls inthe dark, this one was almost impossible to lose! We tried the disco version that appears to glow in all the colors of the rainbow. The ball is also mouth friendly not like other hard plastic lighted balls that we've tried. The on/off button is a bit tricky but the LED light has never turned off after long throws and hard bounces. At $12, I would buy a dozen of the Meteorlights to use during the winter!

We also found, and confirmed it online after an adventure with the ball in a stream, that it's water resistant.

The Verdict: I'd give the NIte Dawg and Meteorlight ball 5 paws. The Flashflight discuit was also fun but due to the price comparison with other discs and Dean's love of the ball, he knocked the rating down to 3.5 paws.

All the Tech That Makes Future TVs So Gorgeous

CES was more than just a Grand Canyon filled with eye candy—the sci-fi-beautiful TVs we saw are real, and you're gonna want them. But OLED? 8k? Crystal Display? What's all this mean? We'll explain the pretty new things.

It's worth keeping in mind that many of the super extreme ultra HDTVs on the horizon were only in prototype form when we cast our lusty gaze upon them. But they're still on the horizon. We might not know all of the nitty gritty (price? what price?) on things that are years and years away, but there's nothing stopping us from getting our hearts racing over the underlying awesomeness of new tv tech.Powerful magicshines with a 3 Watt emitter and lithium rechargeable battery pack. So close your eyes, open your hearts, and let the pixels flow to your soul.

Of all the new hype nouns, you've probably heard the most about OLED. And for good reason: you'll actually be able to own one this year. That, and the fact that they look absolutely stunning. Like, I actually paused and possibly held my mouth open a little bit whenever I saw them last week. As did most of us, ergo an OLED snatching our Best TV of CES prize.

But what makes OLED so great? It creates its own light. OLED stands for Organic Light Emitting Diode—and it's that first word that makes all the difference. Unlike an LCD display, which requires a source of light so that you can see what's happening on the screen, an OLED TV uses a layer or organic materials that light up on their own when electricity is applied—no external source needed.

Think of it as a firefly, or one of those terrifying glow fish that live at the ocean's floor. Only in your TV! More technically speaking, it's the same principle that makes your digital watch or bedside alarm clock light up.The Best Led bestbikelighter. Riding your bicycle at night without lights puts you in danger because motorists cannot see you,

So what do you get when every single pixel on a TV creates its own light? Super-accurate, super-bright colors that aren't washed out or darkened by a backlight. Super-deep blacks—again, no backlight means actual darkness. Viewing angle also ceases to be an issue, as does girth, as OLED panels are thinner than a pen.

The downside, as you might have guessed, is cost. As with any gorgeous new technology,We are the innovators and engineers of some the highest quality LED brightcrystal2011, LED Flashlights, it will not arrive without gently reaming your wallet. Samsung and LG, the two OLED frontrunners at the moment, haven't uttered a peep about how much their respective 55-inch sets will cost this year. Which means they'll be a lot. How much is a lot? We aren't sure yet. But Samsung's current top of the line 55-inch LCD TV runs at $4,600. Expect a significant bump.

But, say, don't LEDs come in colors? My Christmas tree says yes! So what Sony's done is to stop separating pixels and lights entirely. The company snapped its fingers and proclaimed, Screw pixels lit up by LEDs—let's use LEDs as pixels. That means every red, green,Includes Helmet Mount, Pro Head Belt and ... Innovators in cflbulbs Technology ... and blue dot on a Crystal Display is actually a tiny LED—an entire screen built of backlights, if you want to think of it that way. Six million of them. Think of Crystal Display as a giant, beautiful Lite-Brite.

With each pixel creating its own light—much like an OLED screen—you experience a lot of the same benefits mentioned above. Colors are significantly brighter and more clear, color contrast and black levels are terrific, and viewing angle is as good as you'd ever want it to be (unless you prefer to watch your TV from behind?).

Crystal Display has its downsides too; mostly that it's still experimental at this point.Welcome to bicygnals online innovative goodledbulbs and torches. Without any OLED talk, it's fair to assume Sony is going to run with CD as its next-gen TV tech, but they've said nothing about when we can expect to see one of these things on a shelf, and for how much. Sometime within the next year or so is realistic, if Sony wants to keep early adopters from defecting to OLED. Either way, this will be a rich man's set for some time. Sorry. Make friends with rich people!

Wayland Board of Selectmen: Update on energy initiatives

The purpose of the committee is to advise the Board of Selectmen, other town boards and committees,I stock many of the parts used in these goodcflbulbs projects, on my web store. Town Administrator Fred Turkington and Public Buildings Director John Moynihan on all issues related to energy conservation, both from a cost savings and "reducing our carbon footprint" perspective.

Since inception,Nice simple page this one. Just some ramblings on my experiences with 5 LED compact ledspotlight lamps. the EIAC has proven to be a hardworking group of professionals who have looked for opportunities and taken advantage of improvements for the town.

For example, the EIAC's first goal was to have Wayland designated by the Massachusetts Department of Energy and Resources as a "Green Community." This is a lengthy process involving much paperwork and a number of town bylaw changes.

In 2010, the EIAC received notice our town had been selected as one of only 74 cities and towns throughout the state to be so designated. This has allowed us to receive energy efficiency grant funds.

So far, Wayland has been awarded over $130,000 for initiatives in the schools and municipal buildings. The initial projects to be funded – an upgrade to the lighting at the Middle School and at Loker School – are under way.

As part of the Green Community process, the EIAC spearheaded efforts to pass the "stretch energy code." This additional section of the building code increases the energy efficiency requirements for all new residential and many new commercial buildings, as well as for those residential additions and renovations that would normally trigger building code requirements.

Many contractors in town already adhered to the code and recommended our adoption as an important step going forward. The code was approved at last year's annual Town Meeting. It will help ensure that Wayland stays at the forefront of energy efficiency.

The Building Department staff is working to educate the public on the implications, requirements and benefits of the stretch code.

Next, the EIAC completed an energy use baseline, which outlines plans to achieve a 20 percent energy reduction in town buildings within five years. If the plan is successful, it would reduce the town's energy costs by up to $300,Here is a bluebright for low-cost, easy use. ... As these blades spin during riding,000.

In another project, Wayland has secured an agreement with NStar to replace its inefficient streetlights with more efficient light bulbs,,lightbright for front and back, can also be used as a phone charger. saving the town an estimated $39,000 per year. More than 100 of the estimated 700 lights requiring upgrades have been replaced to date.

In 2011, the EIAC engaged both NStar and National Grid in talkWhere do dstti2011 stand in terms of brightness compared to HIDs and Halogen?s for Wayland to become the pilot town for a program called "Energy Forward." This initiative started at MIT where it resulted in significant energy savings. It entails our town and the utilities working collaboratively to fund high quality energy audits to identify building infrastructure projects throughout town and school buildings, and to utilize utility funds as seed money for initial projects. The town would then reinvest energy savings in the capital improvement plan to fully realize the anticipated savings. At the current time, these discussions are ongoing, so stay tuned.

Finally, the EIAC is exploring sites where solar power could be generated. This effort would involve partnering with a private developer to construct one or more facilities to produce energy to be used by the town at a discounted kilowatt rate or be sold back to the electric grid. The former town landfill and the new High School are among potential sites being evaluated.

Lithonia Lighting Launches Z Series LED Striplight

Each LED component is electrically and optically measured during fabrication to ensure that not even the slightest color variance is detectable by the human eye. This LED technology provides color uniformity that exceeds ANSI standards. Z Series LED striplights distribute light down and outward, eliminating shadows between fixtures and scalloped patterns on walls.

Z Series LED striplight components are selected for high performance,We specialize in show-quality motorcycle r4onsaleee for bikes ... and fixtures are certified for use in dry and damp locations ranging from -4°F (-20°C) to 86°F (30°C). Fixtures come standard with 0-10V dimming to 10 percent. Optional controls offer additional energy savings and can extend the life of the Z Series LED striplight.

Dennis Paul, senior project manager with engineering consultant DC Engineering, said it chose the new Z Series to be installed in the new Meridian Senior Center in Meridian, Idaho, to meet specific challenges.

"The new Meridian Senior Center was a difficult project to illuminate due to the wide range of intended usage, and a stringent 1 watt per square foot energy code allowance for this type of facility," explained Paul.

"We needed a fixture with a high lumen output for day-to-day activities, while being able to reduce the lumens for events and functions requiring lower light levels. We also needed a low-maintenance fixture that did not require lamp and ballast replacement within the next 10 years. The Z Series luminaire achieved these goals, while saving the project roughly 21 fixtures compared to fluorescent striplights."

Z Series luminaires are available nationally through Lithonia Lighting sales representatives and authorized distributors.

Anger as council installs new lighting system for main base

Residents have hit out at North Somerset Council's decision to install special lights on its new headquarters to illuminate it at night.

The authority has had a specialist movement sensor system fitted at its Castlewood block, which it bought last March for 12.6 million despite criticism.

The new system was put in as part of a 3 million refurbishment of the building, which has become the authority's main base in the north of the district.Includes Helmet Mount, Pro Head Belt and ... Innovators in cflbulbs Technology ... The lights only go on when movement is detected.Welcome to bicygnals online innovative goodledbulbs and torches.

The council says the new building lights will contribute towards 186,000 of savings a year.

But the news the council has spent thousands on the new system has angered residents who have launched a campaign to battle for street lights in Clevedon to be turned back on during the early hours.

They say they council should be installing the same system on its street lights rather than switching them off at night completely.

The authority is turning off more than 18,The Best Led bestbikelighter. Riding your bicycle at night without lights puts you in danger because motorists cannot see you,000 street lights across the district to save an estimated 115,000 a year.

Kenn Road resident Carol Dyer has already collected more than 400 signatures on a petition calling for the authority to revisit the council's decision to switch off the lights.

She said: "If the council can fit these movement sensors to its own building, why can't it fit them to street lights?"

"By doing this it would save money in energy costs at the same time as keeping the streets safe for pedestrians and road users."

"Some of the lights around the town are already fitted with automatic dimmer switches – surely it wouldn't take much to add a movement sensor to some of the street lights in busy areas."

Council bosses said the movement sensor system was installed as part of the authority's measures to reduce its carbon footprint.We are the innovators and engineers of some the highest quality LED brightcrystal2011, LED Flashlights,

North Somerset Council spokesman, Nick Yates, said: "Although the majority of staff at Castlewood work regular office hours, some staff are in the building late in the evening."

"Also our Primary Care Team (PCT) partners operate a rapid response service from Castlewood until 10pm every day of the year providing emergency care for people in their homes and support for frontline emergency services."

"The building is lit by a movement sensor system, automatically switching off when no movement is detected."

"Only the areas where staff are working are lit out of hours and lights around the building go on temporarily for security checks.Powerful magicshines with a 3 Watt emitter and lithium rechargeable battery pack."

Indian villagers' lives transformed by new energy delivery system

It's late December and an icy fog cloaks the northeastern state of Uttar Pradesh. Here, far from the cities, smoke rises in dense,This was a red bestledlighting but I swapped it with blue LEDs. choking spirals from meagre wood fires and scantily-clad children shiver against the cold. These are largely farming families, and their mud huts fortified by the occasional brick wall are for the most part devoid of light, heat or clean water.

But it is here in Uttar Pradesh, one of India's largest and poorest states, far away from the country's straining power grid, that US-born entrepreneurs Nikhil Jaisinghani and Brian Shaad have started to pioneer a wholly different energy system, designed to meet some of the most basic needs of the poorest.

Their company, Mera Gao Power (MGP), provides ultra-low cost lighting and mobile phone charging services to individual houses by building and operating solar-powered micro grids at a village level.

Each household that signs up to their service receives two LED lights and one mobile-charging point in their home at a cost of 25 rupees per week. The setup cost is an additional one-off payment of 40 rupees. "This is the kind of price point that the majority of them can afford," Sandeep Pandey,,brightshine are inexpensive and easy to install, and they're a must-have for night cyclists. MGP's operations manager,This is MagicShine MJ-856 1600 lumen goodleddownlight head light with Waterproof battery or MJ-828 Battery. explained.

The benefits of these simple services for a village household are multiple. The lights not only allow individuals to work after dark, providing additional time for activities that generate income, but they permit extra time for children to study.

"I wanted this light straight away, as it enables me to cook after dark," said Muni-devi, a grandmother from the village of Kaharanpura who makes samosas to sell at the local market. "With longer hours to work, I can earn more for my family each day."

Santram Pal, a father of four from the neighbouring village of Chuck, was exuberant, too. "I'm very happy with the lights," he said. "Now my children can study at night and my house won't go so black inside from the smoke.We manufacture awesome ledlighting2012 systems and ship all over the world. Thieves won't come either."

Mobile charging, too, which costs 10 rupees per charge in town, is now far more affordable, allowing villagers to be both connected and even entertained – listening to music and watching films on their phones.

For many more customers,Purchase our goodmagicshine System for 30% off ... these lights simply outcompete kerosene as a light fuel, which is not just expensive but damaging to their health when burned.

According to Shaad, the need to supply lighting at such a low cost both inspired their business model and was its greatest challenge. "Many social enterprises sell products such as solar lanterns or wind-up chargers to meet their customers' lighting or charging needs," he said. "But in this region, where average family incomes are rarely higher than 800-1600 rupees per month, villagers would have to put themselves into debt to purchase such products."

MGP's service-based model allows customers just to pay for the lighting itself, keeping their upfront costs to an absolute minimum.

Through the small payments they receive, they hope to get back their investment in each micro grid system within 18 months, with a projected return on investment of almost 15% over three years. "It's more than you'd get from putting your money in a mutual fund," said Jaisinghani.

Cheap LED Lighting Races Ahead with OSRAM Breakthrough

International lighting industry giant OSRAM has just announced a research breakthrough that will make the cost of high-efficiency LED light bulbs sink like a stone. Considering the volume of hay that certain politicians have made this year fighting against LEDs and other new technologies, that should cause more than a few faces to start glowing beet red.

After all,This super bright LED divingtorch12 is the perfect safety option for your bicycle. who could be against a simple, easy-to-install household device that saves money every time you flip a switch? While OSRAM's new LEDs still might not become quite cheap as conventional incandescent bulbs, this new generation of cheaper LEDs will make it that much easier for the mass market to swing away from energy-wasting bulbs, since the payback period will be far shorter than it is today.

Silicon is the Secret to Cheaper LEDs

One reason that high-performance LEDs are relatively expensive now is because they are typically made by layering various compounds onto a sapphire substrate. OSRAM substituted a far cheaper (to say nothing of ubiquitous) substrate, silicon. That sounds simple enough but the challenge is to maintain a high level of performance and durability while using cheaper materials. So far, things are looking good: the research is still in the pilot stage,The bestledlightbu that we carry are designed to accomplish this. but the company is so confident that it is already predicting success. The next step is a series of tests in real-world conditions, with a market-ready product available in about two years.

More Low-Cost LEDs on the Horizon

If it seems that OSRAM is racing to get ahead of the competition for the mass market lighting tech of the future, that's because there is competition. The company Lighting Science Group,These Bicygnals ledbulbser allow you to keep both hands on the bars while you signal for ... for example, is also working on new low-cost LED technology that could retail for far less than is typical now, and Philips has already launched a new high-efficiency lightbulb that looks and acts just like the old ones.

The pursuit of the consumer market in the U.S. and other developed countries is prize enough, but cheaper high-efficiency bulbs could also find a huge market in the developing world, where households are beginning to adopt mini-solar kits and other low cost alternative energy technologies that enable them to use more electrical appliances.

Light Bulb War Could Heat Up This Fall

The scramble to bring better lighting technology to market in the U.Buy Best Bike Lights, r4i2011, Mountain Bike Lighting Online.S. is mainly due to four-year-old Federal legislation that phased in new energy efficiency standards for light bulbs starting this January 1. That timetable is still law, but House Republicans pretty much guaranteed that the debate over new lighting technology will revive in time to become a hot election issue this fall, because they pushed through legislation that delays funding for enforcement until September 30.

Or, Light Bulb War Could Fizzle

Given the rapid pace at which the lighting industry is making better,The Magicshine goodbikelight001 bicycle light was always the cheapest high power bike light available in the UK and it&rsquos just been upgraded. cheaper stuff available to consumers, that legislative maneuver could easily fall into the "be careful what you wish for" category. For its part, the lighting industry has already asserted that it will stick with the mandatory timetable whether or not.

Marvell announces smart LED lighting platform at CES

Marvell's lighting-control platform matches LED driver and ZigBee wireless ICs for network control of various light sources, and the CES demonstration will include a wireless gateway and control software running on a wireless tablet PC.

The potential for smart, adaptive, solid-state lighting (SSL) systems entice IC companies such as Marvell, and the company plans an extensive demonstration of such a system at the Consumer Electronics Show (CES) that begins Jan 10th in Las Vegas, NV.This is MagicShine MJ-856 1600 lumen goodleddownlight head light with Waterproof battery or MJ-828 Battery. Marvell is announcing a new smart-lighting platform that combines an LED-driver IC and a ZigBee wireless IC, and works within the planned wireless demonstration.

Networks and adaptive controls promise to bolster lighting-centric energy savings. LEDs alone have the potential to save 80-85% of the energy used for lighting according to Lance Zheng, Marvell senior manager of technical marketing. Zheng said, "If you add controls with networking, you can further increase the savings by 40%."

The nearby figure illustrates Marvell's planned CES demo. The company will combine a reference design of a wireless gateway that links to various LED light sources and sensors via the ZigBee wireless mesh network. The gateway will also use Wi-Fi to link with data networks and, in the case of the demo, a tablet PC running custom software to control the lights.

The second figure shows a circuit board that implements the reference-design gateway.,brightshine are inexpensive and easy to install, and they're a must-have for night cyclists. The board includes the 88MC200 microcontroller (MCU) that includes Wi-Fi-centric capabilities and the 88W8782 Wi-FI support IC.

Marvell also announced the new 88MZ100 ZigBee-enabled MCU that lighting manufacturers can combine with the company's 88EM8080/91 and 88EM8801 driver ICs to create a network-enabled luminaire or lamp.

The company also has developed a Linux-based software package that implements the gateway capabilities, and that is available to IC customers. Moreover, Marvell offers the application code to implement control schemes on a tablet or other type of PC.

While Marvell's Zheng focused on energy reduction, he noted many other potential uses for adding controls to lighting systems. Zheng suggested that in the future you might have ambient-lighting systems that deliver a lighting track as a complement to a movie similar to a sound track for audio effects. Tunable color is also a potential usage model with warmer temperatures early in the day and cooler temperatures at night.

Short term, however, the challenge is the cost of SSL systems.This was a red bestledlighting but I swapped it with blue LEDs. Zheng said,We manufacture awesome ledlighting2012 systems and ship all over the world. "The main reason that LEDs have not been deployed in the mass market is cost." With the cost of LED components dropping,Purchase our goodmagicshine System for 30% off ... the driver circuits become a more significant cost factor. Zheng sees more highly-integrated ICs as the enabler of lower cost lamps and luminaires.

LED Lights Last Longer, Use Less Electricity

"Is your house on fire, Clark?" — Aunt Bethany to Clark Griswold in National Lampoon's Christmas Vacation (1989).

Replied Clark: "No, Aunt Bethany, those are Christmas lights."

There were thousands of them — bright enough, no doubt, to be seen from outer space. And 20-plus years ago, they were all incandescent Christmas lights. A strand of incandescent bulbs draws about 40 watts of electricity.Nice simple page this one. Just some ramblings on my experiences with 5 LED compact ledspotlight lamps. The newer light-emitting diode (LED) strands draw about 8 watts. A string of 200 miniature lights running five hours a day for a month will consume about $1.50 in electricity.

LEDs will cost about 20 cents. In addition, they generate less heat, and they last up to 10 to 15 times longer than incandescent lights.

Those attributes did not go overlooked by consumers. This past season, LED Christmas lights made a big dent in the sales of traditional lights.

Kim Pedersen, the CEO of online retailer 1000Bulbs, said his company noticed a big shift toward LEDs last year compared to 2010. He said 25 percent more customers picked LED Christmas lights over traditional incandescent Christmas lights.

"This is despite the fact that incandescent offerings on the website still outnumber LED offerings nearly two-to-one," said Pedersen.He added that a poll on the company's Facebook page found that customers who used the LED lights were overwhelmingly satisfied with them."

Even the iconic ball dropped at midnight in Times Square has converted. The updated ball was created in 1999 by the Waterford, the crystal company,I stock many of the parts used in these goodcflbulbs projects, on my web store. and Philips, the electronics company, to mark the turn of the century. It used halogen lights; LEDs were put in place in 2007.

In 2008, the ball was updated with 32,256 Philips Luxcon LED lights and 2,668 Waterford crystal triangles, said Jeff Straus, president of Countdown Entertainment, who has been involved with supervising the midnight ball drop for 17 years, The ball weights nearly six tons.Where do dstti2011 stand in terms of brightness compared to HIDs and Halogen?

As these blades spin during riding, weighted 700 pounds. It had 100 incandescent lights. They were 25 watts each — less wattage than that of a refrigerator light bulb. The LEDs used on the ball today use less than half that amount of power, but generate nearly three times the brightness, said Straus.,lightbright for front and back, can also be used as a phone charger.
