LED + SSL

The latest issue of WIRED Magazine features a cover story about the future of LED lighting. Interesting reading, and mostly accurate. Check it out here.

The U.S. Department of Energy has published an updated version of the guide, LED Luminaire Lifetime: Recommendations for Testing and Reporting, developed by a diverse group of experts under the auspices of DOE and the Next Generation Lighting Industry Alliance. This guide is the latest edition in a series of publications on LED product performance [...]

The SQ-LED thermoplastic emergency light is touted by Mule Lighting as “the most economical LED emergency light available today.” Compared to typical “bug-eye” units, the use of LED lamps instead of traditional incandescent lamps reduces the size of the unit by 50%. The SQ-LED is suitable for all types of applications, from commercial to retail. [...]

The Lighting Research Center recently announced that it will host another LED Lighting Institute, a three-day hands-on seminar where participants learn the basics of LED technology and gain an understanding of LED system integration issues involving electrical, optical, and thermal characteristics of LEDs. Participants will learn how to measure and evaluate LEDs and LED systems, [...]

Flicker and stroboscopic effects have been a concern with solid-state lighting (SSL), and industry and the ENERGY STAR program have debated recently the effects of frequency and other driving modes on the perception and acceptability of flicker. To provide further data and guidance in this area, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute [...]

Guest post by Jim Brodrick, Department of Energy Because solid-state lighting has the potential to last longer than traditional lighting technologies, addressing product reliability or lifetime has been a key issue for SSL. So it’s not surprising that lifetime was one of the topics under discussion at the U.S. Department of Energy’s (DOE) sixth annual [...]

Lunera Lighting, Inc. recently announced the 5400 SERIES, claiming the world’s first LED luminaire certified for Armstrong’s TechZone Ceiling Systems, which can reduce installation time and cost in addition to helping provide a clean visual ceiling. The 5400 SERIES features a CRI rating of 85 with an R9 measurement of nearly 70. The efficient, linear [...]

Cree, Inc. has announced the acquisition of Ruud Lighting, Inc. at an estimated net cost of approximately $525 million. Combining two highly complementary LED innovators, the acquisition allows Cree to extend its leadership position and increase the adoption of energy-efficient LED lighting. The companies’ shared focus on best-in-class LED-based systems has led to thousands of [...]

Acuity Brands, Inc. recently announced that it has received expanded accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP) for testing of LED products for conformance to the Illuminating Engineering Society of North America LM-79 standard. NVLAP is administered by the National Institute of Science and Technology (“NIST”) and evaluates the competence of testing and [...]
