Motion Activated & Light Sensor
Turn the switch to AUTO, the lamp will be the motion-activated mode. It will turn on automatically when you come close and automatically turns off after 20 seconds of no motion detected. It will turn on only when it is dark and when motion is detected.
Constant Light
Turn the switch to ON, the light will always on. Turn the switch to OFF, it will turn off. Just like a normal led ceiling light, and you can control it by the light button to turn on/off.
