LED bulbs move in and mix up home lighting
In the space of a few years,However, the marketing muscle of Philips led light lighting could give Philips LED business an advantage.Compact fluorescent lights have solved LED lighting supplier many of the problems associated with traditional filament light bulbs. I've gone from one lighting technology to another and now to three lighting types in my home. I suspect others will be in the same shoes as lighting options expand,I tested the U600 alongside the 250U, our previous R4ds Editors' Choice. On a clear spring day, notably those involving LEDs.
Eager to cut down my electrical load, I essentially converted to compact fluorescent lighting (CFLs) years ago. Recently, though, I've replaced CFLs with efficient LED bulbs and even energy-hogging incandescents to address an unfortunate feature of CLFs: turning them on and off frequently degrades their life.
CLFs are still a good deal both financially and environmentally. They use about one quarter of the energy of incandescent bulbs and will last about 10 years, or 10 times as long, according to Consumer Reports tests. But Consumer Reports also found that turning a CFL on and off within less than 15 minutes, something you might do in the bathroom for instance, leads to earlier-than-expected brownouts.
That rapid cycling issue, plus the arrival of good LEDs in the traditional A19 bulb shape, got me rethinking my home lighting and prodded me to use different bulb types for different purposes. I'm still focused on efficiency, so I'm only using incandescent bulbs in places where the light is used in short spurts. I tend to go in and out of the attic quickly, for example, and want full brightness as soon as possible.
I've also added a few LEDs, which are certainly more expensive--a 60-watt incandescent replacement costs almost $40--but functionally they have been good CFL replacements and are more efficient per lumen. I have a few Philips LEDs that give off as much light as a 60-watt incandescent or a 14-watt CFL, and they consume 12 watts.
It will take a long time based on energy savings compared with CFLs to recoup the initial cost. On the other hand, LEDs are supposed to last upward of 20 years, and I placed them in fixtures that we flick on and off frequently, which I hope will address the burnouts I've experienced with CFLs.
LEDs multiply
You don't yet see general-purpose LED bulbs at the supermarket or corner hardware store, but more products in the popular 60-watt-equivalent category are coming, and prices are expected to continue falling. In the space of the last few weeks, a couple of new LED companies have emerged, and one anticipated product (well, anticipated by lighting geeks at least) is expected in stores soon.
Switch Lighting,Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs.Unlike compact cfl bulbs fluorescent light bulbs, LED based light bulbs provide a variety of lighting options- including the ability to provide a wide range of light, which allows them to act as a proper replacement light bulb backed by venture capital firm VantagePoint Capital Partners, plans in the fourth quarter to start selling an LED bulb which has a cooling system that it says will ensure long life--on the order of 20,000 hours, or 18 years, at three hours a day. The company is readying 40-watt, 60-watt, and 75-watt equivalent bulbs, with prices starting at less than $20, according to a representative. To make light dispersal more even, the LED light sources--small coin-size dots--are located near the edge of the bulb glass, a change from the typical "snowcone" shape.
