LED + SSL

Here’s an interesting application for LEDs: growing food on other planets. Researchers at the University of Guelph’s Controlled Environment Systems Research Facility (CERF) are studying LEDs as a light source that can facilitate plant growth in environments where nutrients and electricity are scarce, such as space and even during colonization efforts of other planets. The [...]

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently evaluated a newly constructed building at Siena College—Rosetti Hall, a 25,000 square foot, 3-story, contemporary brick building that includes classrooms, meeting rooms, and offices. The New York State Energy Research and Development Authority (NYSERDA) awarded funding to change the lighting specification from the originally specified [...]

The U.S. Department of Energy has released a report on a GATEWAY demonstration of LED lighting at the University of Florida’s Nadine McGuire Theatre and Dance Pavilion in Gainesville. Four interior spaces—the acting studio, dance studio, scene shop, and dressing room—were fitted with LED luminaires or retrofit lamps along with dimming controls. In addition, the [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy [At] LIGHTFAIR International, we saw a lot of T-LEDs (LED T8 replacement lamps), and it’s clear that manufacturers are putting a great deal of thought into how to make those products better, brighter, and easier [...]

This new IES document provides a method for measuring light output and color maintenance of LED lamps, light engines and luminaires. Check it out here.

The Department of Energy’s Municipal Solid-State Street Lighting Consortium (MSSLC) has released the first updated version of its Model Specification for LED Roadway Luminaires. A “living document” that’s updated as needed to reflect changes in technologies and associated standards, and incorporating feedback from users, the model specification enables cities, utilities and other local agencies to [...]

The Institution of Engineering and Technology recently released the Code of Practice book on LED lighting. This Code of Practice has been developed to provide confidence to users as a minimum standard for LED lighting systems installation, as well as to serve as a useful reference on the application of LED lighting systems. Topics covered [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy If you attended LIGHTFAIR International last week in Las Vegas, we hope you got a chance to stop by DOE’s booth and catch our SSL educational presentations that played to SRO crowds throughout the show.

The California Lighting Technology Center recently tested 26 LED A-lamp products marketed as alternatives to 60W incandescent A-lamps. Data collected on power (W), voltage (V), luminous output (lumens), correlated color temperature (CCT), color rendering index (CRI), rated life, and dimming performance allowed for comparison with manufacturers’ claims as well as current lamp quality standards. The [...]
