The Wireless Motion Activated Spotlight detects movement up to 30 ft. away and responds with a superbright (300 lumen) beam of white LED light. This rugged, weatherproof unit runs on battery power, so it can be installed in minutes, without an electrician or an AC outlet. To save power, the light shuts off 30 seconds after motion has ceased, and a light sensor prevents activation during the daytime. Perfect for home or business, it's an ideal solution for driveways, alleys, back doors, patios, staircases, delivery entrances and more.
