The U.S. Department of Energy has published Energy Star criteria for LED lamps, posted by Jim Brodrick, the DOE's point-person on solid state lighting (and various other matters) via the LightNow blog. The criteria, which apply to "integral" LEDs for replacement applications, take effect Aug. 31, 2010.
Says Brodrick, "...a profusion of LED replacement products has entered the marketplace, and many of them are disappointing, to put it mildly. In general, performances haven't lived up to the claims. That's a guaranteed recipe for consumer dissatisfaction. Publication of the new ENERGY STAR criteria for integral LED lamps is a key step in creating order out of this chaos."
