5. Operating Instructions
The LUTEC flood light offers multiple operating modes. Please refer to the controls on your specific unit for mode selection, which may include switches or dials for sensitivity and time settings.
5.1 Dusk to Dawn Mode
In this mode, the built-in sensor detects ambient light levels. The flood light will automatically turn on at full brightness when it gets dark (dusk) and remain on throughout the night. It will then automatically turn off when daylight returns (dawn).

Image: This image visually demonstrates the Dusk to Dawn operating mode, showing the flood light automatically turning on as darkness falls and turning off with the arrival of daylight. Note: In this specific mode, the motion sensor is typically inactive.
5.2 Motion Sensor Mode
When activated, the motion sensor detects movement within its detection range and angle. Upon detection, the light will turn on for a set duration (adjustable via controls on the fixture) and then turn off if no further motion is detected. This mode is ideal for security and energy saving.
Refer to the specific controls on your fixture to adjust motion sensitivity and the duration the light stays on after motion detection.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your flood light.
- Cleaning: Periodically clean the light heads and sensor lens with a soft, damp cloth to remove dirt, dust, or debris. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.
- Inspection: Annually inspect the wiring and connections for any signs of wear, damage, or corrosion. Ensure all mounting screws are tight.
- LEDs: The LED light source is designed for long-term use and is not user-replaceable. If the LEDs fail, the entire fixture may need replacement.
7. Troubleshooting
If you encounter issues with your flood light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
