The Illuminating Engineering Society of North America (IES) has announced a new document, Projecting Long Term Lumen Maintenance of LED Light Sources (TM-21-11). The document recommends a method for projecting the lumen maintenance of LED light sources from the data obtained by the procedures found in IES document Approved Method for Measuring Lumen Maintenance of [...]

As the incandescent A-lamp begins phaseout starting January 1, 2012, consumers have a new source to become educated about their energy-efficient lighting choices: LumenNow.org, created by Lighting Understanding For a More Efficient Nation (LUMEN), an ad hoc consortium of organizations and professionals such as NEMA and the Alliance to Save Energy. The site includes general [...]

Lithonia Lighting has expanded its RTLED family of LED ambient luminaires with 2×4 and 1×4 models. Powered by an advanced light engine, the RTLED luminaires delivers high color rendering (80+ CRI) and 3500K color temperature. These luminaires are factory enabled with the nLight intelligent controls interface, which provides full-range 0-10VDC dimming plug-and-play connectivity to occupancy [...]

In 2012, Department of Energy regulations will change the way some commercial users light their buildings. In July 2012, regulations will eliminate some linear fluorescent and halogen PAR technologies in lieu of options that operate at a higher efficacy, offering significant energy savings. To ensure a smooth transition, GE Lighting has developed a tool to [...]

The Illuminating Engineering Society of North America has announced the publication of The Lighting Handbook, 10th Edition, the most comprehensive one-volume reference on lighting. The Lighting Handbook presents all phases of lighting and integrates the views of IES Committees and individual specialists in each knowledge area. First published in 1947, The Lighting Handbook is recognized [...]

NEMA’s Electroindustry Business Confidence Index for current North American conditions gained ground in August, but remained below levels suggestive of industry-wide expansion for a third straight month. The index climbed to 41.4, up 9.4 points from its July reading. The survey’s measure of the degree of change in current North American conditions was in negative [...]

Commercial and high-rise residential buildings, including federal buildings, must now meet requirements in the ASHRAE/IES 2007 energy standard after rulings issued by the Department of Energy. Prior to the new rules, federal and commercial buildings had to meet requirements in the 2004 standard. ANSI/ASHRAE/IES Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, has [...]

Cree’s LED Module LMR4 was created to overcome common design issues that manufacturers face when trying to incorporate LED solutions into luminaires. The module integrates driver electronics, optics and primary thermal management, making it drop-in ready to new luminaires.
