Next Generation Lighting Systems Competition

Performance Requirements

General Requirements

Conversion (retrofit) kits and controls to be installed per National Electric Code. Typical space layouts are provided in Appendix A – Typical Evaluation Spaces.

Lighting Performance Targets

Task Plane Illumination
Illuminance Uniformity
Maximum Luminance Ratio
Average initial at full power Average to minimum across work plane Between task and immediate background surfaces Between task and distant background surfaces (ceiling, walls, floor)
45 – 55 fc 2:1 3:1 10:1 or 1:10

Note: all values based on the IES Handbook, 10th edition.

Control Performance

  1. System shall provide for vacancy control (manual on/auto off) of two zones, (indicated on the specific room layout provided to approved entries), with a time out period of 5 minutes.
  2. System shall provide manual continuous dimming of the same two zones indicated in item 1. Minimum dimming level of each zone shall be ≤ 10% of lumen output.
  3. System shall provide daylight harvesting to maintain task plane illumination at the current level provided by the electric lighting (whether full output, task-tuned, or manual dimmed). When daylight contribution exceeds task plane illumination, luminaires shall operate at lowest dimmed level (stay illuminated until switched off manually or by presence detection control).
  4. System shall provide field-adjustable high-end trim to lower maximum system light output. System shall be delivered with high-end trim set at 100%.
  5. Manual dimming control takes precedence to establish the specified task plane illumination. Daylight harvesting should not override to raise light levels to the maximum task plane illumination if the manual dim setting is not at full.
  6. Control settings shall be adjustable by the user without factory assistance.
