Defiant DFI-8800-WH provides both motion detection and automatic dusk-to-dawn lighting control for outdoor areas. The motion activation feature can be set to trigger the light on for durations between 10 seconds and 10 minutes, while the dusk-to-dawn sensor ensures that the light turns on automatically at dusk and off at dawn. The device is also equipped with a "TEST" mode that allows you to temporarily override the motion sensor and keep the light on for 5 seconds to facilitate setup and testing.
