Next Generation Luminaires Design Competition

Evaluation Criteria

Judges will score each entry according to the following criteria:

  • Color appearance - Evaluation of this criterion will be based on the judging panel's evaluation of the color appearance of the installed luminaire. Manufacturer data about CCT of the LED sources must be provided. CCT of all finalists will be verified through IESNA LM-79-08 testing.
  • Color rendering - Evaluation of this criterion will be based on the judging panel's evaluation of the color appearance of objects illuminated by the installed luminaire. Manufacturer data about CRI of the LED sources must be provided. CRI of all finalists will be verified through IESNA LM-79-08 testing.
  • Appropriate illuminance - Horizontal and/or vertical illuminance for the application must be appropriate according to accepted lighting practice. Evaluation of this criterion will be based on the judging panel's evaluation of the light levels and distribution (uniformity and contrast) provided by the luminaire, and may also include measurement of light levels using a standard illuminance meter.
  • Appropriate luminance - This criterion addresses luminance of the luminaire surface. Judges will evaluate luminaire brightness in conditions as similar as possible to the intended application to assess glare and contrast. Photometric luminance of the luminaire will be verified through IESNA LM-79-08 testing of finalists.
  • Application efficiency - The luminaire must deliver appropriate light levels to the task with lower wattage than comparable traditional light sources for that task. Evaluation of this criterion will be based on assessment by the NGL judging panel. Luminaire input watts and volt-amps will be verified.
  • Aesthetic appearance and style - Evaluation of this criterion will be based on the judging panel's subjective evaluation of the aesthetic appearance of the installed luminaire.
  • Serviceability and replacement - Entries must demonstrate attention to specifier and user concerns about follow-on service and replacement in the event of component failure.

The judging panel may award bonus points for entries exhibiting desirable characteristics. Bonus points will be available for the attributes listed below; additional bonus points may be identified by the judges.

  • No off-state power use - Luminaire designs that do not draw power when the luminaire is turned off. Consistent with ENERGY STAR SSL requirements, up to 0.5 W of off-state power draw is allowed for luminaires with integral occupancy, motion, or photo-controls, or individually addressable luminaires with external control and intelligence.
  • Dark-sky friendly - Outdoor luminaires that are shielded to limit upward light emission, and minimize sky glow and light trespass. Especially useful information in evaluating outdoor luminaires includes ratings by lighting zone for backlight, uplight, and glare (BUG rating).
  • Adjustability/Flexibility - Products which demonstrate white light and beam spread adjustability.
