Okay, maybe not. But the technology available for LED building illumination has come a long way in a surprisingly short amount of time.
According to the Pacific Northwest National Laboratory, LED technology is moving so quickly that next-generation products are entering the market every six months, feeding a global illumination market that approached $2 billion in 2007, according to Strategies Unlimited.
Check out this graphic based on information provided by the U.S. Department of Energy in March 2008. DOE says there will be commercially available cool-white LED devices with an efficacy of 150 lumens/W in about 1-2 years and similar warm-white LED devices in about five years.
As efficacy increases and costs come down, LED products will become positioned for widespread use in general lighting.
