![]() Therefore, during the day when natural light is present, the light will not activate when motion is detected, which saves energy. The dusk-to-dawn feature of a light will cause your motion light to activate only when it is dark. This feature uses a small photocell to detect the presence of available and/or existing light. If light is detected, the motion light will not trigger. If light is not detected, the light will turn on once motion is detected. Dusk-to-dawn LED fixtures are triggered on and off by the amount of light reaching the fixture’s sensor, making them suitable for outdoor areas such as streets, roadways, parking lots, and pedestrian areas.
