LED + SSL

I wrote this article for the July issue of tED Magazine. Reprinted with permission. LED performance continues to increase, making it increasingly competitive with traditional lighting, while costs continue to fall, making it increasingly attractive for purchase. According to the U.S. Department of Energy (DOE), between 2005 and 2013, average efficacy of cool-white LED packages [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy There’s a growing awareness of glare these days, both within and beyond the lighting community. Glare can be a problem with any lighting technology, but the nature of LEDs as point sources [...]

I was pleased to contribute a special editorial section on LED lighting to the April issue of BUILDING DESIGN + CONSTRUCTION. It includes an article about the state of the art in LED luminaires, new products plus a tour of several design projects exemplifying the effective use of LED lighting. Click here to check it [...]

The U.S. Environmental Protection Agency (EPA) recently announced the release of the final ENERGY STAR Luminaires V2.0 specification, which will replace V1.2 on June 1, 2016. Click here to learn more and download the specification.

Product cycles in the lighting industry have shortened to as short as 1-2 years for LED products, which is of course problematic for specification into projects that can take years to develop. In this ARCHITECTURAL LIGHTING article, manufacturers provide tips to specifiers on how to navigate the issue. It’s a very interesting topic. Click here [...]

I wrote this article for the March issue of tED Magazine. Reprinted with permission. The U.S. Department of Energy’s (DOE) 2010 Lighting Market Characterization estimated some 180 million lamps were in service in outdoor stationary lighting installations. More than half of these were HID lamps, predominantly high-pressure sodium and metal halide. Some 19 million LED [...]

Interesting article in ELECTRICAL CONTRACTOR about growth in development and adoption of OLED lighting, which holds a lot of promise for certain applications. Click here to read it.

The Department of Energy continues to be a strong supporter of LED market development. As with previous LIGHTFAIR events, this year, DOE held a series of informative seminars in their booth. Topics included intelligent lighting, color tuning, new color metrics and more. Download all of the presentations here.

The seventh annual Next Generation Luminaires (NGL) Solid-State Lighting Design Competition has recognized 28 commercial LED indoor and outdoor lighting products for excellence. Sponsored by the U.S. Department of Energy (DOE), the Illuminating Engineering Society, and the International Association of Lighting Designers, NGL was launched in 2008 to encourage technical innovation and promote excellence in [...]
