This product easily converts any light socket into a 360 degree motion sensor light. First, turn off your light switch. Next, screw our adapter into any indoor ceiling light socket, then screw in any incandescent (25W-100W) or compact fluorescent (10W-30W) light bulb to the adapter. Turn the light switch on. The motion sensor turns on your lights when it senses motion from all 360 degrees and turns them off four minutes after motion subsides, saving electricity costs. Our adapter senses motion 120 degrees within 20 feet. Great for closets, basements and garages!
