The U.S. Department of Energy (DOE) has published a report, Lumen Maintenance Testing of the Philips 60-Watt Replacement Lamp L Prize Entry, after completing 18,000 hours of lumen maintenance testing. Long lifetime is a much-touted potential advantage of solid-state lighting and one of the L Prize competition requirements. The minimum test period defined for the [...]

LED technology holds significant promise for airfield lighting in the U.S, mainly in terms of the potential for longer operating lives and increased efficacy of LEDs compared to incandescent lamps, the most common light source on airport runways and taxiways today, according to a new report: Issues with Use of LED Airfield Lighting: ACRP Synthesis [...]

Guest post by Ted Konnerth, EGRET Consulting Group As the electrical industry merges into the electronics industry, I thought it appropriate to review the financial implications of that transition. I recently reviewed a summary of margins and net earnings for technology sectors of consumer electronics*. The summary compared 5 notable companies (Sony, Toshiba, Philips, Apple [...]

Rensselaer Polytechnic Institute’s Lighting Research Center (LRC) will hold a three-day, hands-on seminar September 18-20, 2012, to teach industry professionals how to incorporate light-emitting diodes (LEDs) into lighting applications. The LED Lighting Institute will include updated technical content based on the latest industry developments. Through workshops and lab sessions, participants learn the basics of LED [...]

The Department of Energy has published the first evaluation report from a GATEWAY demonstration on NE Cully Boulevard, a residential collector road in Portland, OR. Six different types of roadway luminaires were installed in side-by-side groupings and evaluated for initial performance: three LED, one induction, one ceramic metal halide, and one baseline high-pressure sodium. In [...]

Originally published in TED Magazine, April 2012. More than $5 billion in commercial lighting rebates are offered in nearly eighty percent of the United States, according to Leendert Jan Enthoven, president of Briteswitch, LLC, a firm that locates, optimizes and does all the paperwork to obtain rebates, incentives and grants for commercial end-users. In 2012, [...]

The U.S. Department of Energy has completed Series 15 of testing through the DOE Solid-State Lighting CALiPER program. A summary of the results is now available for download on the DOE SSL website here. Report 15 of testing analyzes the performance of a group of 10 LED floodlights that mirrors the broad range of conventional [...]

The U.S. Department of Energy (DOE) has published a report that looks at the direct and indirect material and process inputs to fabricate, ship, operate, and dispose of LED lamps, compared with incandescent lamps and compact fluorescent lamps (CFLs). LED Manufacturing and Performance is the second part of a larger DOE project to assess the [...]

Solid State Luminaires recently unveiled TERRASCAPE, a durable landscape accent light with sealed 15° spot, 25° narrow flood, 40° flood and 60° wide flood distribution and 3000K or 4000K color temperatures. TERRASCAPE features a 45° positive dual aiming lock system (180° rotation). The housing is constructed of marine grade, die-cast aluminum for long lasting performance.
