Mr. Beams MB564 Wireless Motion Sensor Activated Compact Led Path Light, 4-Pack, Black Brown Provides 30 lumens of bright led light that cover 50 square feet. MB564 is a four-pack of the Mb560 compact path light. Each light contains a motion and light sensor so it only turns on when it detects motion in the dark. It also automatically shuts off 20 seconds after motion stops to conserve battery life. Durable, weatherproof design allows it to be used anywhere without being affected by weather conditions. Two mounting options - in ground with the included stake or on walls with the included hardware - allow the light to be installed on any path, stairway or patio in less than 5 minutes without the hassle of wires. Each light requires 4 aa batteries (not included) that provide 30 hours of light.
