15W Radar Microwave Motion Sensor LED Light with Auto Dimming for Home, Stairs, Parking, Warehouse, Lobby and More – Recessed (White)
Product description
This motion activated LED light is perfect for lighting stairways, garages or any area that needs automatic illumination. With a detection range of up to 9 meters, it will turn on when motion is sensed in low light conditions to provide up to 1500 lumens of bright white light. The light has a durable metal housing designed for indoor use and it is powered by 15W of energy efficient LEDs that will last over 30,000 hours. It features automatic dimming so the light fades out slowly instead of abruptly shutting off. Easy to install with included mounting hardware, this sensor light switches on only when needed, helping to save energy while improving safety and visibility around your home.
