6. Operating Instructions
The motion sensor allows for customizable operation based on your needs.
6.1 Adjusting Motion Sensor Settings
The motion sensor unit has two adjustable dials located on its underside:
- Timer Minutes: Controls how long the light stays on after motion is detected. Settings range from 10 seconds (Test mode) to 10 minutes.
- Feet: Adjusts the motion detection range, from approximately 10 feet up to 72 feet.
For optimal performance, ensure the motion sensor is positioned to face the desired detection area and that the adjustment controls are facing downward to prevent water ingress.

7. Maintenance
To ensure the longevity and optimal performance of your LEPOWER Security Flood Light, follow these maintenance guidelines:
- Cleaning: Periodically clean the light heads and motion sensor lens with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Inspection: Regularly inspect the wiring and mounting for any signs of wear, damage, or loose connections. Address any issues promptly.
- LED Lifespan: The integrated LEDs have a long lifespan of approximately 50,000 hours and do not require replacement.
8. Troubleshooting
If you encounter issues with your security light, refer to the following common troubleshooting steps:
- Light not turning on: Check the power supply at the circuit breaker. Ensure all wiring connections are secure. Verify that the motion sensor is set correctly (not in 'Test' mode for continuous operation).
- Light staying on too long/short: Adjust the 'Timer Minutes' dial on the motion sensor.
- Motion sensor not detecting: Adjust the 'Feet' sensitivity dial. Ensure the sensor head is pointed towards the desired detection area and not obstructed.
- False triggers: Reduce the 'Feet' sensitivity. Ensure the sensor is not pointed at heat sources, moving objects (like tree branches), or reflective surfaces.
