This LED uses just 6 watts.

As with other technologies, advances in lighting just keep coming. Now that you’re somewhat comfortable with CFL — compact fluorescent lamp — bulbs, get ready for things to change again. The latest generation of LEDs — light-emitting diodes — are here and manufacturers claim they rival the look, dimming ability, and light quality of incandescents. Better yet, LEDs contain no mercury, and last up to five times longer than CFLs and 50 times longer than incandescents. They are pricey, many sell for $60 or more, but could save about $300 in electrical cost over its life compared with an incandescent.

OK, so you’ve done the environmentally correct thing and replaced most of your incandescent bulbs with CFLs (Compact Fluorescent Lightbulbs).
CFLs use less electricity and as a result, reduce greenhouse gas emissions. In an average home, lighting accounts for about a fifth of the electric bill. Because CFLs use about 75 percent less electricity than incandescent light bulbs — and last about 10 times longer, it just makes sense to switch.

From Green Right Now Reports:

Lighting and energy experts have been scratching their heads for sometime over how to make LED lighting as effective and pleasant as CFLs, because LEDs are even more energy efficient than CFLs.

Renaissance Lighting, based in Herndon, Va., appears to be inching forward in this effort. The company will be showcasing its new, all white solid-state LED downlight fixtures at the LIGHTFAIR International 2009 at the Javits Center in New York City. The new fixtures are brighter than ever and have two and half times greater efficacy.

An item in the New York Times last week served as a good wrap-up of recent developments on the LED front, finding places (beyond traffic lights) where light emitting diodes are getting a toehold as replacements for less energy-efficient lights.

But does it, in newspaper terms, “bury the lead”?
