- Motion Sensor: Detects movement to activate the lights automatically.
- On/Off Switch: Located on the unit for manual control.
5. Setup and Installation
Follow these steps to properly set up and install your solar motion sensor wall light:
- Choose an Installation Location: Select a location that receives direct sunlight for at least 6-8 hours daily to ensure optimal charging of the solar panel. The recommended installation height is 1.5-3.5 meters (5-12 feet).
- Mount the Wall Bracket: Use the provided mounting screws and wall plugs to securely fix the wall bracket to your desired surface.
- Activate the Light: Locate the ON/OFF switch on the underside of the solar light unit. Slide the switch to the 'ON' position.
- Attach the Solar Light: Carefully slide the solar light unit onto the fixed wall bracket until it clicks securely into place.
- Adjust Light Heads: Adjust the three light heads and the solar panel to your preferred angles to maximize light coverage and solar exposure. The light heads offer a 270° wide lighting angle.

6. Operating Instructions
The Lepro WL4000 Solar Motion Sensor Wall Light operates automatically once installed and activated:
- Daytime Operation: The solar panel charges the internal lithium-ion battery during daylight hours. The light will remain off.
- Nighttime Operation: At dusk, the light will enter standby mode. When motion is detected within its 16-26 feet range, the light will automatically turn on at full brightness.
- Auto-Off Function: The light will remain on as long as motion is detected. After approximately 20 seconds of no detected motion, the light will automatically turn off to conserve battery power.

- Clear Obstructions: Ensure no new obstructions (e.g., growing branches, new structures) are blocking direct sunlight from reaching the solar panel.
8. Troubleshooting
If your solar light is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on at night. | Insufficient solar charge. | Ensure the solar panel is in direct sunlight for 6-8 hours daily. Clean the solar panel. |
| Light is dim or stays on for a short period. | Low battery charge. | Allow the light to charge for a full day in direct sunlight. |
| Motion sensor is not detecting movement. | Sensor is obstructed or dirty. | Clear any obstructions from the sensor. Wipe the sensor clean. Ensure the light is installed within the recommended height and detection range. |
| Light turns on during the day. | Light sensor malfunction or external light interference. | Ensure the solar panel is not covered or in a dark area during the day. If the problem persists, contact customer support. |
