It utilizes a Lutron Radio Powr Savr wireless occupancy sensor (sold separately) and a Lutron dimming driver to automatically set light levels based on occupancy. Utilizing LEDs as the light source (included) has lower power usage saving over 90 percent of lighting energy usage while meeting building codes and standards. Ideal for stairwells, corridors, and hallways.
