UK-Funded Study Publishes “Consensus View” For Circadian Lighting Recommendations

On March 17th, 18 circadian lighting researchers published a “consensus view” of circadian lighting recommendations, titled: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults, in the journal PLOS Biology. The authors include well-known circadian lighting researchers, George Brainard and Steven Lockley.

RPI’s Bob Karlicek on Spatially Tunable Lighting

For an upcoming article in Electrical Contractor Magazine, I recently had the opportunity to interview Bob Karlicek, Ph.D., Professor of Electrical, Computer and Systems Engineering at Rensselaer Polytechnic Institute, Director of the Center for Lighting Enabled Systems and Applications, co-Director of the Energy, Built Environment and Smart Systems Institute at Rensselaer. The topic: spatially tunable lighting, which LightNOW first reported on in August. Transcript follows.
