Stop wasting electricity on empty rooms! This 4-pack of commercial-grade PIR (Passive Infrared) ceiling sensors is perfect for warehouses, garages, storage areas, or any space with high ceilings (up to 40 ft). They easily plug into compatible LED high bay or UFO lights (just rotate off the old blank cover and plug this in). When someone walks into the area, the light instantly ramps up to 100%. When they leave, it dims down to a standby level (you can set it to 0%, 25%, 50%, or 75%) after an adjustable 'hold time' (3-15 minutes). You can tweak all the settings – hold time, daylight threshold (so it doesn't turn on when there's enough sun), and standby time – using the knobs on the unit or a remote. It saves energy, extends your bulb life, and adds smart, hands-free convenience. The detection diameter is about 50 ft on the wall and 40 ft on the ceiling. A professional, set-it-and-forget-it solution.
