This product is perfect for creating a warming glow for pathways and buildings, as well as deterring intruders. This LED bulb (included) is switched on automatically by the built-in infrared motion sensor. It will only activate by a heat source (people and animals) and not create false alarms from objects that may blow past it in the wind. Features an override function so you can use it as normal light when required by switching the main switch on and off twice within 2 seconds.
