DOE Releases Report on FAA Demonstration of LED Walkway Lighting

The U.S. Department of Energy (DOE) recently released a September 2008 report, Energy Savings Estimates of Light Emitting Diodes in Niche Lighting Applications. Today DOE published an Errata to the report regarding the refrigerated display case energy savings estimates. Specifically, the installed base of refrigerated display case fluorescent lighting systems in the U.S. was given in linear feet of display cases instead of, as labeled in the September report, the number of refrigerated display cases. This correction impacts calculations throughout the report. Read more »

U.S. Department of Energy publishes final report on SSL efficacy for todays products

Downlight Comparison: Efficacy vs Light output DoE SSL luminaries test shows a huge discrepancy between manufacturer claims and actual tested luminaire performance. Numerous products for differnt applications were tested in three rounds. To give consideration to real-life conditions off state power consumption (standby power) was taken into account. Pilot test results were published in December 2006, first round results followed in March 2007. Now Final results are published for free distribution in the public interest for noncommercial, educational purposes. Read more »
