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.
