The Honeywell 3000 Lumen LED Motion Sensor Security Light is an energy efficient solution to enhancing the overall security of your home or place of work. Once motion is detected, the LED security light illuminates to provide safe bright white light, wherever light is needed. This motion sensing light can easily be mounted and is designed to withstand most weather conditions. The dusk-to-dawn sensor feature allows for energy savings and you don't have to remember to turn the light off or on. The LED security light activates at dusk and deactivates at dawn on its own.
