When motion is detected, the light turns on automatically, and if the sensor does not register activity for about 45 seconds, it turns off automatically. The sensor offers a detection range of up to 3 meters and a detection angle of 120°, providing convenient and energy-efficient lighting control. With the option for recessed or surface mounting and a detachable sensor head, it is suitable for various types of furniture and installations.
