The combination of occupancy controls, a bi-level generator, and an induction source produces an energy-efficient luminaire with exceptionally long life, good color quality, and dynamic light level response based on actual usage. The bi-level controls contribute additional savings that are directly proportional to automotive and pedestrian traffic patterns. Bi-level luminaires reduce to 50% power on vacancy and increase to 100% power on occupancy. Switching between high and low light levels based on occupancy maintains sufficient light for security and way-finding, while maximizing energy savings. Bi-level exterior products for parking lots and garages typically achieve 30 – 75% energy savings compared to traditional luminaires.
