The Lighting Research Center recently announced that it will host another LED Lighting Institute, a three-day hands-on seminar where participants learn the basics of LED technology and gain an understanding of LED system integration issues involving electrical, optical, and thermal characteristics of LEDs. Participants will learn how to measure and evaluate LEDs and LED systems, [...]

LIGHTFAIR has announced a call for speakers for next year’s conference in Las Vegas May 7-11, 2012. The deadline to submit a proposal is September 12, 2011. Click here for more.

Flicker and stroboscopic effects have been a concern with solid-state lighting (SSL), and industry and the ENERGY STAR program have debated recently the effects of frequency and other driving modes on the perception and acceptability of flicker. To provide further data and guidance in this area, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute [...]

Guest post by Jim Brodrick, Department of Energy Because solid-state lighting has the potential to last longer than traditional lighting technologies, addressing product reliability or lifetime has been a key issue for SSL. So it’s not surprising that lifetime was one of the topics under discussion at the U.S. Department of Energy’s (DOE) sixth annual [...]

Recently, LightNOW covered the rare earth phosphor shortage created by export restrictions by China, the world’s main supplier. As lamp manufacturers are forced to raise prices, OSRAM SYLVANIA says it is also responding with a new line of 4- and 8-ft. T8 lamps that feature “optimized phosphor formulation,” making them more resistant to material cost [...]
