The U.S. Department of Energy’s CALiPER program has released a Snapshot Report on indoor LED luminaires, which utilizes the LED Lighting Facts® program’s extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products. Based on data through the first quarter of 2014, the report [...]

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.
