In the June issue of LEDs Magazine, Dr. Nadarajah Narendran, Director of Research at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, discusses LRC research focused on LED system reliability in the article, "Industry test standards must evolve to ensure accurate LED system life estimates." 

The Lighting Research Center has released a new version of its free, open-access circadian stimulus (CS) calculator with more robust and flexible functionality to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces.
