I recently produced a special section on LED lighting for the April issue of BUILDING DESIGN + CONSTRUCTION Magazine. Check it out in BD+C’s digital edition here (LF4-LF24, an insert between PP. 42-43).

The National Academy of Sciences (NAS) has published a report, Assessment of Advanced Solid-State Lighting. The NAS committee reviewed the development and future impacts of SSL, including projections of cost and research and development (R&D) necessary to overcome barriers to widespread adoption. The report recommends: * Continue investments in LED core technology, aimed at increasing [...]

My lighting column in the April 2013 issue of ELECTRICAL CONTRACTOR addresses LED product maintenance. Over the past months, I’ve had the opportunity to work with the IES Maintenance Committee on revising RP36, and conducted extensive interviews with manufacturers and others about maintaining LED products. As you might suspect, they’re not quite maintenance free. Click [...]

The Department of Energy’s booth at LIGHTFAIR was hopping, with in-booth educational sessions packed with attendees. Experts addressed life-cycle assessment and environmental testing of LED products; performance of LED troffers, kits, and tubes; dimming and flicker; and provided updates on the L Prize® and Next Generation Luminaires competitions, LED Lighting Facts testing, CALiPER analysis, and [...]
