But a related question that has spawned a certain amount of confusion and misinformation is how safe LED lighting is for the human eye. To answer it, the U.S. Department of Energy (DOE) has […]Read More

No previous research has tuned the temporal characteristics of light-emitting devices to enhance brightness perception in human vision, despite the potential for significant power savings. The role of stimulus duration on perceived contrast is unclear, due to contradiction between the models proposed by Bloch and by Broca and Sulzer over 100 years ago. We propose […]Read More

This is a link to an article that covers “biologically optimized” school lighting design by ZNL & Osram.  Based on the study, “social jetlag” can be remedied by the daylight simulation – keeping more students awake in the classroom.   LEDs Magazine – Optimized lighting conditions help students improve performance.Read More

Dr. Lockley & Rod Heller recommends this free software that can enhance our circadian rhythm. f.lux F.lux fixes this: it makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day. It’s even possible that you’re staying up too late because of your computer. […]Read More

Task ambient lighting, which is using relatively low ambient lighting together with task lights when more light is required, is one of the best strategies for energy efficiency and good lighting. But it is often not specified optimally, and it is significantly underutilized.  We now have a new generation of cost effective dimming and CCT […]Read More
