LED + SSL

The Wisconsin Energy Center will be hosting an LED webinar, “Exploring LED Lighting Technology for Facilities” presented by Liesel Whitney-Shulte, on May 22, 2012, 1:00 to 2:30 PM Central Time. Learn more here.

The U.S. Department of Energy (DOE) has completed Series 14 of testing through the DOE Solid-State Lighting (SSL) CALiPER program. A summary of the results is now available for download on the DOE SSL website at www.ssl.energy.gov/reports.html. Report 14 of testing focused on LED downlight retrofit units. Eleven units were tested in a 6-inch insulation [...]

The U.S. Department of Energy (DOE) has published the final evaluation report from a retrofit of track lighting used to illuminate a special photography exhibition at the J. Paul Getty Museum in Malibu, California. During the demonstration, 12W LED PAR38 lamps replaced 60W halogen PAR38 30° flood lamps on a one-for-one basis across three adjacent [...]

The U.S. Department of Energy (DOE) recently published the final report from a demonstration of LED technology in ornamental post-top street lights, conducted in Sacramento, CA. This report provides an overview of the evaluation of four different LED replacement products using computer simulations, field measurements, and laboratory testing. The evaluation was conducted by DOE’s Municipal [...]

Guest post by Jim Brodrick, Department of Energy [Recently], DOE reopened the PAR 38 category of the L Prize competition. As you might recall, we suspended that category in January 2011 for retooling. Why? In order to incorporate lessons learned from the competition’s 60W replacement lamp category. The changes made will streamline and improve the [...]

LEDs are currently dominating product development in the lighting industry, but still only represent about 5-10% of luminaire sales, and only 1% of the installed base of lamps in the United States, as shown below. And most of that is traffic signals and exit signs. This is a sobering reminder that LED lighting is still [...]

Pure Edge Lighting’s new showroom at the Dallas Market Center features LED products and innovative and artistic installations. Pure Lighting and Edge Lighting, both owned by Gregory Kay, recently merged to become distinct brands under the company Pure Edge Lighting. Due to growth, the company moved from a shared space to its own expansive showroom [...]

The discussion about LEDs as an energy and environmental cure-all has led to some skepticism about whether LEDs are truly big energy-savers and green when one considers the total lifecycle energy and environmental cost of the product, including manufacturing and transportation. To its credit, DOE took this seriously enough to commission a study. The first [...]

On April 19, the U.S. Department of Energy will host a 90-minute live webcast on a new lighting specification that sets performance requirements for high-efficiency LED and fluorescent troffer products in 2’x4′, 2’x2′, and 1’x4′ configurations. Developed by DOE’s Commercial Building Energy Alliances (CBEAs), High-Efficiency Troffer Lighting Specification v3.0 was released in February and expands [...]
