Full Answer

Dusk to dawn porch lights are usually activated by a photocell, which is a device that senses light. The dusk to dawn light will turn on when the photocell does not detect sufficient natural light. When the photocell detects light, it will turn the fixture off. This design allows the lamp to provide lighting only when it is needed to illuminate the surrounding area.
