Dorcy 41-1071 Floodlight Motion-Sensing Battery Powered LED, grey.

The new and improved motion light has been redesigned for better light output and a sleeker look. This light uses new LED technology to provide safe, bright light anywhere you need it--without the need for wires. Three D cell alkaline batteries (not included) will run the motion sensor light for more than 1 year without changing batteries (based on average use). A sophisticated motion sensor coupled with a photo sensor ensures that the light will only turn on when it is dark and motion is detected. The light automatically turns itself off. The 41-1071 comes with a 4-way swivel mounting bracket and hardware for easy installation.
