I recently had the pleasure of interviewing Jeannine Fisher Wang, PE, LC – Director Business Development, Acuity Brands. The topic: OLED lighting–where it is now, where it’s going. I’m happy to share her responses with you here. The interview informed an article I wrote for the November issue of tED. DiLouie: How would you characterize [...]

ENERGY STAR is a voluntary testing and labeling program that verifies that energy-efficient lighting products provide comparable performance as incumbent-technology products while saving energy. ENERGY STAR is used as a qualification for product rebates by a number of utilities. On June 1, the EPA released the new (final) Luminaires v2.0 spec, which will replace v1.2 [...]

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 [...]
