LED + SSL

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy [At] LIGHTFAIR International, we saw a lot of T-LEDs (LED T8 replacement lamps), and it’s clear that manufacturers are putting a great deal of thought into how to make those products better, brighter, and easier [...]

This new IES document provides a method for measuring light output and color maintenance of LED lamps, light engines and luminaires. Check it out here.

The Department of Energy’s Municipal Solid-State Street Lighting Consortium (MSSLC) has released the first updated version of its Model Specification for LED Roadway Luminaires. A “living document” that’s updated as needed to reflect changes in technologies and associated standards, and incorporating feedback from users, the model specification enables cities, utilities and other local agencies to [...]

The Institution of Engineering and Technology recently released the Code of Practice book on LED lighting. This Code of Practice has been developed to provide confidence to users as a minimum standard for LED lighting systems installation, as well as to serve as a useful reference on the application of LED lighting systems. Topics covered [...]

The California Lighting Technology Center recently tested 26 LED A-lamp products marketed as alternatives to 60W incandescent A-lamps. Data collected on power (W), voltage (V), luminous output (lumens), correlated color temperature (CCT), color rendering index (CRI), rated life, and dimming performance allowed for comparison with manufacturers’ claims as well as current lamp quality standards. The [...]

AT LIGHTFAIR, DOE experts presented on a wide range of solid-state lighting topics. These presentations, plus other materials, are now available for free download here.

There are many LED solutions available to upgrade from fluorescent T8 or T12, from new luminaires to retrofit kits and replacement lamps. Utility rebates for these LED solutions are growing but still not widespread. Here’s a BriteSwitch graphic showing what’s available now, based on their database. Learn more here.

Effective June 13, 2014, the U.S. Department of Energy suspended the L Prize PAR38 Competition. No entries will be accepted. The L Prize Competition launched in 2008 as the first government-sponsored technology competition designed to spur development of highly efficient, high-performance LED replacement products. A winning entry in the 60W replacement lamp category was awarded [...]
