Fluorescent lights in the freezer cases at an Albertson's grocery store in Eugene, Ore., were retrofitted with LED strip lighting, resulting in a 61% energy savings in the lighting alone, in a demonstration sponsored by the U.S. Department of Energy's Solid-State Lighting Gateway Technology Demonstration Program. Adding occupancy-based controls—in this case, WattStopper FS-705 Wide Angle PIR occupancy sensors—produced another 12% in energy savings. The FS-705 sensor is specifically engineered for use in freezer cases.
