LED Journal recently published “The Impact of the ‘California Quality LED Bulb,'” an insightful article by Bernie Weir of ON Semiconductor on the impact of the new California Quality LED Lamp Specifications. 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 This week, the U.S. Department of Energy’s (DOE) CALiPER program released an exploratory study on the problems and benefits likely to be encountered as LED products intended to replace linear fluorescent lamps and luminaires become [...]

The U.S. Department of Energy (DOE) has released an exploratory CALiPER study on the problems and benefits likely to be encountered as LED products intended to replace linear fluorescent lamps become increasingly popular. Eighteen lighting designers and facility engineers compared 24 identical pairs of troffers in a simulated office space. Three of those pairs involved [...]

The Telelumen Light Replicator enables any light to be recorded either in an instant or over time, matched by software, and reproduced.

The fifth annual Next Generation Luminaires (NGL) Solid-State Lighting Design Competition has recognized 28 commercial LED indoor lighting products for excellence. Sponsored by the U.S. Department of Energy (DOE), the Illuminating Engineering Society of North America, and the International Association of Lighting Designers, NGL was launched in 2008 to promote excellence in the design of [...]

I’m an admirer of Dave Irvine-Halliday, founder of the Light Up The World Foundation, and had the opportunity to hear him speak at LIGHTFAIR and more recently here in Calgary, where he teaches. The Foundation provides market-based lighting solutions to regions of the world without easy access to electricity typically in the form of solar-powered [...]

The Department of Energy recently published the evaluation report from a GATEWAY demonstration in New York City’s Central Park, conducted in collaboration with The Climate Group and the New York City Department of Transportation. LED post-top luminaires from five different manufacturers were installed along paved walking trails and evaluated against the metal halide luminaires that [...]

Summary of a research idea conceived at the Catalonia Institute for Energy Research, Lighting Group. This video explains the potential applications of a novel concept based on LEDs than uses a microprocessing unit to reproduce and read spectra in spaces.

The California Energy Commission (CEC) has published a voluntary quality specification for omnidirectional and directional LED replacement lamps intended to replace screwbase incandescent lamps in light fixtures other than colored lamps, light strips and rope lights, linear pin-based lamps and integrated light fixtures. Research conducted by the California Lighting Technology Center resulted in two conclusions. [...]
