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.

Conduit-hub-mount controls are often used with electrical enclosures, junction boxes, and light fixtures. They fit a 1/2 conduit trade size, so you can mount them anywhere a compatible knockout is available. A rubber O-ring seals out moisture. Those with a pivot or swivel head let you adjust the position of the sensor to align the photocell with a light source and sensing area.

On at sunset, off at sunrise controls turn on at sunset and off when the ambient light is above a certain level.
