New tool to calculate Optimized Light
Good Light indoors has spectral characteristics that vary according to time of day, personal needs, and specific tasks. In the morning and during daytime, the light spectrum should include a reasonable portion of short wavelengths to support the energizing and revitalizing effects of light. In the ...Read more..

DOE Report on LED Lamps Shows Improvements For Consumers
Consumer adoption of LED lighting is still rather low both in North America and Europe. One of the reasons for this is the claims made by manufacturers; specifically the LED equivalent to a standard incandescent or halogen lamp. As in the early days of compact fluorescent, the light levels expected ...Read more..
DOE Publishes GATEWAY Report on Pedestrian Friendly Outdoor Lighting
Although this report was designed and developed for the US market, the insights and recommendations are valid for all countries looking at using LEDs for pedestrian applications. One of the key points raised - uniformity - is a classic example of where LEDs with good optics can provide a safer envir...Read more..
DOE Publishes Report on Accelerated Life Testing of SSL Luminaires
