LED + SSL

Long life has been promoted as a key advantage of LEDs, but understanding and communicating how LED products fail and how long they last is essential. The U.S. Department of Energy has published a new SSL Technology Fact Sheet, Lifetime and Reliability, to help users understand typical causes for LED product failures, the difference between [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy DOE has released a much-anticipated new report that estimates the savings from using SSL in applications where LEDs compete with traditional sources. Entitled Adoption of Light-Emitting Diodes in Common Lighting Applications, the report not only [...]

The U.S. Department of Energy (DOE) has released a report analyzing markets where light-emitting diodes (LEDs) compete with traditional lighting sources (e.g., incandescent and fluorescent). The report, Adoption of Light-Emitting Diodes in Common Lighting Applications, provides estimates of current energy savings, plus potential savings if these markets switched to LEDs overnight. Nine markets were analyzed: [...]

The Designers Lighting Forum of New York recently announced its “Call for Speakers” for LEDucation 8, a single-day exhibition and educational event dedicated solely to the ever evolving LED market and technology. LEDucation 8 will return to New York City March 18-19, 2014 in a new two-day format and in a new venue–the Sheraton NY [...]

Stephen Blackman, President and Chief Design Officer, BlackJack Lighting, recently published a whitepaper about OLED technology that really got me thinking about its design possibilities. I enjoyed the opportunity to interview him about his vision concerning the potential for OLED as a lighting technology. DiLouie: Why OLED? Blackman: OLED is a very exciting, up and [...]

Kenall Lighting’s Nate Heiking makes the case that L90 may not be all it’s cracked up to be when evaluating rated life for LED luminaires. What do you think? ARCHITECTURAL SSL has the story here.

Dan Mellinger, PE, LC, Lighting Strategy Manager for Efficiency Vermont, recently published a whitepaper that discusses the future of commercial efficiency programs and LED lighting. It addresses the significant opportunity that remains, despite years of fluorescent upgrades, and the importance of controls and design. Check it out here.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy In two previous Postings and a Technology Fact Sheet, we’ve discussed the possible effects of LED lighting on our biological clocks. But a related question that has spawned a certain amount of confusion and misinformation [...]

To address the issue of how safe LED lighting is for the human eye, which has generated some confusion and misinformation, the U.S. Department of Energy has published a new fact sheet, Optical Safety of LEDs, which clarifies what’s known about the issue and provides information about current standards for photobiological safety. The main optical-safety [...]
