The competition recognized 37 commercial LED lighting products for excellence, including four Best in Class winners, which earned the distinction for clearly exhibiting superior performance overall and standing out in their respective categories. Three entries were also chosen for special consideration because of the interesting form factors used in their design. The innovative, energy-efficient products that were selected demonstrated high lighting quality and consistency, glare control, serviceability, and value as determined by the 2012 judging panel.

The DOE, the Illumination Engineering Society of North America (IESNA), and the International Association of Lighting Designers (IALD) jointly manage the NGL competition, which promotes excellence in energy-efficient LED commercial lighting. In 2012, the NGL competition was split into separate indoor and outdoor competitions with separate judging panels. The judges of the outdoor competition assessed color quality, appropriate illuminance, light distribution, glare control, aesthetic appearance and style, serviceability, value, and energy efficiency.

The 2012 outdoor competition judging took place on November 4-6 at the Virginia Tech Transportation Institute, where 120 entries were installed and judged in realistic roadway, parking-area, parking-garage, and exterior landscape and façade scenarios.

Here we feature the Best in Class luminaires, some of the Recognized products and three products Of Note. Full details and all of the winners can be found at: www.ngldc.org/12/outdoor/winners.stm.
