Light-Sensing Light Controls

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

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).

Programmable Off—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 Sunset/Off at Sunrise—On at sunset, off at sunrise controls turn on at sunset and off when the ambient light is above a certain level.

On at Dusk/Off at Dawn—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.

Turn-Lock Connectors

The curved blades lock into place with a quarter turn. These connectors won’t detach when bumped or pulled, so they’re often used in high-vibration applications, such as on assembly lines or with heavy machinery.

Plugs

Industrial—Reliable performance and long life in manufacturing and processing environments.

Power and Ground Presence Indicator—Check the status of your ground connection. A green light signals that connectors have power and are safely grounded. A red light indicates power only. The lights are visible from any angle for quick identification.
