NGL Indoor Competition 2014
At The LED Show in Los Angeles, CA this past September, the US Department of Energy (DOE) announced 57 commercial LED indoor lighting products recognized for excellence by the Next Generation Luminaires (NGL) Solid-State Lighting (SSL) Design Competition. Jointly sponsored by the DOE, the Illuminating Engineering Society of America (IESNA), and the International Association of Lighting Designers (IALD), the 2014 indoor competition saw 266 total products submitted, with 153 products making it to the final evaluation. The judges awarded four submissions as "Best in Class" and 53 others as "Recognized" winners.
A panel of 10 judges evaluated entries over 3 days in August, reviewing independent testing documentation, photometric files, LED data sheets, and driver specifications. Each luminaire was installed in an indoor environment closely matching the intended product application. Judging took place at the Intelligent Lighting Creations facility near Chicago; a motorized ceiling enabled the luminaires to be evaluated at proper mounting heights.
