During the LightFair International (LFI) conference and exhibition in San Diego, CA (April 26-28), the winners among the commercial lighting products submitted for the US Department of Energy's annual Next Generation Luminaires (NGL) Solid-State Lighting (SSL) Design competition were announced. Following last year's model, the organizers combined the Indoor and Outdoor luminaire announcements, and the judges have recognized 25 out of 93 submissions, with only five of those luminaires taking home Outstanding honors. As CARRIE MEADOWS reports, NGL continues to follow trending technologies and applications; thus this year the judges were also tasked with evaluating two new product categories - connected lighting for indoor use and sports lighting for outdoor use - and designated five products in total as "Notable."

The panel of 11 indoor and 10 outdoor lighting judges, experts in the fields of architectural and outdoor lighting, noted that this year's SSL products exhibited a higher level of lumen maintenance - greater than 85% (L85) at 50,000 hours - than in past years. They also pointed out that for the first time in this competition, 31% of submitted indoor luminaires had CRI greater than 90. Scores were based on color, illuminance, light distribution, serviceability, value, dimming control, and appearance.

Notable luminaires indicate technology trends

Although the panel did not perceive any one of the connected lighting entries to excel over another, they did note that each had merits in different applications. Submissions included Cree's SmartCast Technology and Philips' SpaceWise Technology, both of which have luminaires that feature integrated network controls; and the Enlighted Control Solution, which uses an external controller with networked luminaires.

The panel also found that Eaton's Ephesus Lighting Stadium Pro and KMV's SUFA-A Sports Luminaire - the two sports lighting products that were evaluated - were Notable as they were appropriate for larger venues, but they did not judge the products to be appropriate for smaller recreational installations.
