6. Operating Instructions
The MEIHUA 100W LED Motion Sensor Outdoor Light operates automatically based on motion detection and ambient light conditions.
6.1 Working Mode
The light is designed to work only at night. When motion is detected within its 12-meter range, the light will illuminate for a fixed duration of 30 seconds.

6.2 Motion Sensor Functionality
The Passive Infrared (PIR) motion sensor detects movement of heat-emitting objects within its detection zone. Once motion is detected, the light activates. After 30 seconds of no further motion, the light will turn off.
