The Mr Beams Anywhere Ceiling Lights are wireless ceiling lights with motion sensor and bright LEDs that never need to be replaced. Motion sensor activates the bright white LED light. It's durable weatherproof design allows it to be mounted anywhere. Great to light anything from closets, stairways, patios, and gazebos. Because this unit operated with an LED light, it only costs about $4 a year to operate with normal usage with an LED bulb that has 50,000 hours of use, which lights an area of 260 square feet. It automatically turns on whenever it detects motion, and automatically deactivates if motion is not detected for 30 seconds. It will only work if both darkness and motion are detected.
