ELECTRICAL CONTRACTOR Magazine has published an article that I wrote about ambient/task lighting design schemes. This design approach can provide sufficient general and task illumination in offices, with additional benefits contributed by indirect distribution, while generating significant energy savings. The approach can be particularly advantageous when high, dark or articulated ceilings or required use of [...]

A multitude of factors are preventing a recovery for the beleaguered design and construction industry. Lenders that have been extremely reticent to finance construction projects, budget shortfalls at all levels of government, the ripple effect of overbuilding, a depressed housing market and rising costs of key construction commodities are all contributing to what projects to [...]

The New York City Section of the Illuminating Engineering Society (IESNYC) recently announced the winners of the 2011 Lumen Awards, which recognizes the industry’s most innovative lighting projects. Eleven awards in three categories were bestowed, including the Lumen Award of Excellence, the highest level of recognition for permanent architectural application, the Lumen Award of Merit, [...]

The SQ-LED thermoplastic emergency light is touted by Mule Lighting as “the most economical LED emergency light available today.” Compared to typical “bug-eye” units, the use of LED lamps instead of traditional incandescent lamps reduces the size of the unit by 50%. The SQ-LED is suitable for all types of applications, from commercial to retail. [...]

The Lighting Research Center recently announced that it will host another LED Lighting Institute, a three-day hands-on seminar where participants learn the basics of LED technology and gain an understanding of LED system integration issues involving electrical, optical, and thermal characteristics of LEDs. Participants will learn how to measure and evaluate LEDs and LED systems, [...]
