Imperial Lighting performed a full LED fixture replacement in a municipal parking structure for a Chicago-area suburb. To eliminate increased maintenance costs and safety concerns due to light outages, we replaced 175 watt Metal Halide fixtures with 50 watt LED parking garage luminaires. Since the garage lighting was operating 24 hours per day, the LED upgrade resulted in large annual energy savings in addition to significant maintenance savings. The customer also realized project savings due to a local government energy incentive program for which we facilitated processing.

Since the garage lighting had to be operating 24/7 to comply with a village safety mandate but wasn’t fully occupied at all times, we also installed and programmed multi-level sensors on each fixture. These sensors measure occupancy and ambient light and adjust the light levels accordingly on each fixture. This resulted in an additional 20% of energy savings.
