Automatically turn outdoor lights on and off based on lighting conditions to conserve energy. A time delay prevents false switches due to brief exposure to a light source, so a car driving by or a lightning flash at night won’t signal your light to turn off.

Electrical-receptacle-mount controls can be installed anywhere the base can be wired. You can mount them to a wall using a bracket or integrate them into a light fixture. The three-prong turn-lock plug gives you a secure connection. They require a base (sold separately).

On at sunset, off at sunrise controls turn on at sunset and off when the ambient light is above a certain level. Those with a programmable off setting turn on at sunset and then allow you to set your specific off time. This is helpful when you don’t need to have a light on all night. On at dusk, off at dawn controls turn on about 30 minutes before sunset and off about 30 minutes after sunrise. They activate at higher ambient light settings than other light switch sensors for maximum visibility at dusk, dawn, and twilight.
