DOE Report on LED Area Lights for a Commercial Garage Shows Good Acceptance

Difference in color between the white light of the LED luminaires and the yellow light of the HPS. This U.S. Department of Energy GATEWAY Demonstration project studied the applicability of light-emitting diode (LED) luminaires for commercial parking garage applications. High-pressure sodium (HPS) area luminaires were replaced with new LED area luminaires. The project was supported under the U.S. Department of Energy (DOE) Solid-State Lighting Program. Other participants in the demonstration project included Providence Portland Medical Center in Portland, Oregon, the Energy Trust of Oregon, and Lighting Sciences Group (LSG) Inc. Pacific Northwest National Laboratory (PNNL) conducted the measurements and analysis of the results. PNNL manages GATEWAY demonstrations for DOE and represents their perspective in the conduct of the work. Read more »

DOE Report on Residential LED Lighting Shows Advantage over Conventional Lighting

Installed LR6 downlight modules and LED undercabinet fixture. In August 2008 the Pacific Northwest National Laboratory (PNNL) conducted a light-emitting diode (LED) residential lighting demonstration project for the U.S. Department of Energy (DOE), Office of Building Technologies, as part of DOE’s Solid-State Lighting (SSL) Technology Demonstration GATEWAY Program. Two lighting technologies, an LED replacement for lamps (bulbs) in downlights and an LED undercabinet lighting fixture, were evaluated in the demonstration which was conducted in two homes built for the 2008 Tour of Homes in Eugene, Oregon. The homes were built by the Lane County Home Builders Association (HBA) and Future B Homes. The Energy Trust of Oregon (ETO) also participated in the demonstration project. Read more »

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 »
