Promier Sensor Ball Motion Activated COB LED Ball Light The Promier COB LED Motion Activated Ball Light is perfect for covered entryways, sheds, closets, campers and storage units. Can be operated automatically by movement or can be switched on and off manually. In the auto or motion activated mode, the light turns on only when motion is detected, stays on for 15 seconds and then automatically shuts off. The light stays on as long as motion is detected within 8 feet and shuts off 15 seconds after motion activity stops. The motion activated auto mode only works in darkness. To aim light in a particular direction, ball pivots and rotates in virtually any direction and is held in its base magnetically. The base installs magnetically to most metal surfaces or the peel and stick metal disc. You may also mount the base with a small screw (not included) using the keyhole mount. For added convenience you can quickly remove the ball and use it as a flashlight. The Promier "Grab and Go" Sensor Ball light provides up to 150 lumens of bright light and is powered by 3 AAA batteries (included).
