l.e.s.s. lighting

L.E.S.S. Lighting is a Swiss based startup with an apparently novel new form of light source they call “nano fiber lighting”. According to their site: L.E.S.S. (“Light Efficient Systems”) introduces the next generation of distributed lighting systems as a new alternative to today’s LEDs or discharge tubes. Based on an active nanostructured fiber of the thickness of a human hair, our technology generates high quality light that exhibits both ultra-uniformity and brightness characteristics, surpassing today’s quality standards. In addition, the thinness of our fiber offers a high integration potential and unlimited design potential. Here is an article on their history/success. Their … Continue reading l.e.s.s. lighting

TM-30-15 color measurement standard

The IES has put forth a new color metric standard that is far more comprehensive then the old CRI (Ra) measurement system.  It will take time, but I hope manufacturers and specifiers alike adopt the new system. For a more in depth discussion, check out this Architectural Lighting article. Below is the information from the DOE SSL Postings email: A New Method for Evaluating Color Rendition The Illuminating Engineering Society (IES) has just published an important technical memorandum, TM-30-15, which outlines a new system for evaluating the color rendition of light sources. It was developed by an IES task group that … Continue reading TM-30-15 color measurement standard
