This is the battery-powered outdoor sconce that provides automatic nighttime illumination whenever it detects movement. A motion sensor built into the bottom of the fixture detects movement from up to 22' away and across a 90° angle, initiating illumination well before people approach the light. Powered by four C batteries (not included), the light mounts anywhere on a house with the included bracket and hardware while eliminating the need for hardwiring and proximity to a power outlet. Dual LEDs generate bright white light, they remain illuminated for 20 seconds after the sensor detects motion, and they have two adjustable brightness settings. Made from weatherproof metal and plastic with durable glass panels, the sconce provides year-round reliable illumination. Batteries provide up to one year of power and the LEDs last 30,000 hours. Includes one light. 12 1/2" H x 7" W x 6" D. (3 1/4 lbs.)
