This report summarizes an assessment project conducted to evaluate light-emitting diode (LED) luminaires with bi-level operation in an outdoor parking lot application. The project replaced metal halide (MH) fixtures of nominal 320 watts with bi-level LED luminaires from BetaLED equipped with motion sensors. Quantitative light and electrical power measurements were taken to compare base case MH performance with that of the LED replacement luminaires. Economic performance of the LED luminaires as compared to MH was also estimated and qualitative satisfaction with the LEDs was gauged with a customer survey.
