The Place Anywhere Motion Activated Light.

This battery-powered light can be placed in any enclosed dark space and automatically provides illumination when you open the door. An integrated motion detector senses movement from up to 15' away and automatically activates the LED, providing 80 lumens of crisp, white light in a basement, attic, closet, or pantry. The light mounts as easily as a smoke detector to any wall or ceiling using the two provided screws, and its weatherproof housing allows use in a shower or outdoors. The light only turns on in complete darkness and shuts off automatically when no motion is detected for 30 seconds, ensuring optimal efficiency. The LED lasts up to 30 years and the four C batteries (not included) provide up to 3,200 activations. 2" H x 4 1/2" Diam. (8 oz.)
