New LED bulbs promise bright light and high efficiency.
Just when you thought switching over to compact fluorescent light bulbs was smart, along comes something possibly even smarter.
The LED ligh tbulb is creating buzz even among lighting experts.
Research has found LEDs are comparable not only in brightness to the old incandescents, but much more efficient than even compact fluorescent lights.
LEDs are also built to last 15 years, compared to five years for CFLs and one for incandescents.
"The trick now is to make those LED's more friendly and more warm," says Lightfair International's Jeffrey L. Portman.
And in the minds of many, more affordable.
A single 60-watt equivalent led runs about $40.
That's the price on the led developed by Philips that won a $10 million award from Energy Secretary Steven Chu.
"The LEDs are costly now, but the price is dropping very rapidly. So we have a very bright and cool and thrifty future," Chu says.
Supporters say saving $10 to $11 a year in energy costs more than makes up for the initial outlay.
Analysts expect LEDs to drop to $20 a bulb within two years, which is about what you'll save in energy costs if you buy one now.
