LED (light-emitting diode) technology is moving fast, and with justification, some facility managers have viewed it with a wary eye. Some LEDs on the market do not perform as promised, and the technology is changing rapidly. But new developments from the U.S. Department of Energy (DOE) now make it easier for facility managers to find LEDs that meet manufacturers' claims for light quality, life expectancy, and efficiency. DOE has invested significant effort in supporting LEDs, which, due to their much greater durability and potential for efficiency, DOE calls a revolution in lighting. In December 2008, DOE released the first ENERGY STAR criteria for LED fixtures. DOE also announced the creation of Solid State Lighting Quality Advocates, a new program designed to help purchasers find a wider range of high-quality LEDs. (Contains 2 notes.)
