The winners in the Indoor category of the fifth annual Next Generation Luminaires (NGL) Solid-State Lighting Design Competition were announced on Mar. 20 during LEDucation 7 in New York City. The competition is sponsored by the Dept. of Energy, the Illuminating Engineering Society, and the International Association of Lighting Designers. This year, 28 luminaires were recognized from a pool of 156 entries, and only 99 of the 156 actually made it to the judging phase with market-ready samples and proper documentation.)


The three Best in Class winners were as follows:

Juno Lighting Group’s Trac-Master T254L Cylindra track-mounted accent luminaire;

Digital Lumens XLE-3-10 Xpress High Bay industrial luminaire; and

Acuity Brands/Lithonia Lighting’s W Series LED stairwell luminaire.


The 2012 Indoor Competition reflected continued improvements in LED luminaire ability to address color rendering, as well as increased efficacies. The 2012 winner’s averaged 75/lm/W compared to 65lm/W in 2011, and 37 lm/W in 2008.


The NGL competition was launched in 2008 “to promote excellence in the design of energy-efficient LED luminaires for general illumination in commercial lighting applications” and to serve as a specification resource for designers so they can better navigate the abundance of luminaire offerings in the marketplace. In 2012, the program began to evaluate indoor and outdoor fixtures separately as two competitions. The entries were judged by a panel of 11 lighting industry professionals, and evaluated both as stand-alone fixtures and as installed luminaires, for color, appropriate illuminance, light distribution, glare control, appearance, serviceability, value, and energy-efficiency.
