Next Generation Luminaires Design Competition

Judging Process

The 2012 Outdoor Competition Judging Event took place on November 4-6, 2012 at the Virginia Tech Transportation Institute (VTTI). The dedicated 2012 outdoor competition saw a major advance from 2010, when indoor and outdoor products were combined. In 2012, 120 entries were installed and judged, compared to just 40 outdoor products previously. VTTI provided six separate venues – and experienced staff – for installing luminaires in different contexts. Products were grouped by application and judged in these groups.

The panel of nine judges, drawn from across the outdoor architectural lighting community, evaluated the products by assessing their lighted performance and appearance, construction and serviceability, value, and dimming capabilities (where applicable). The specific evaluation criteria are described elsewhere in this document.

To evaluate the lighted performance and appearance, VTTI staff installed street and roadway luminaires on poles at appropriate heights along the VTTI roadways; parking lot luminaires were installed on a theatrical lighting truss in a parking area. Parking garage luminaires were installed indoors. Other building-mounted or landscape luminaires were installed on and near exterior fa├žades or indoors.

Judges assessed the luminaires and lighted surfaces visually, measured illuminance and luminance, and reviewed photometry from LM-79-08 reports and AGI32 calculations based on application templates (see Evaluation Criteria).

To assess serviceability and the replacement of LED modules and drivers, judges examined and deconstructed additional "tabletop" samples provided by the entrants and considered comments from the VTTI staff who installed the lighted samples.

Judging proceeded in two steps. In order to take advantage of the panel's diverse experience, judges were initially asked to rate products individually, rather than push for consensus. At the end of the initial judging process, the entire judging panel reviewed the group scores and discussed each product. The first consideration was whether each judge would recommend the product for specification: the prerequisite for the "Recognized" winners. Thirty-seven products were ultimately selected by the judging panel by this standard. Three of the 37 products with interesting or innovative form-factor, were identified as "Of Note."

Among the Recognized products, the judges then considered whether any merited "Best in Class" selection. To be awarded "Best in Class", products needed both to rate highly overall and to stand out from the rest of the group. The judges were not required to select a "Best in Class" winner in every category. Four products were selected "Best in Class" this year.

After the onsite judging event, NGL staff conducted additional focused reviews of submitted documentation. Particular attention was given to the LM-79-08 documentation to verify product performance. While it was not possible to verify life claims with certainty, supporting lumen-depreciation and thermal documentation was required and carefully reviewed.
