Operating Instructions
The Ustellar 80W LED Flood Light operates by being connected to a standard 120V AC power source. Once installed and wired correctly, the light will illuminate when power is supplied to its circuit.
- Turning On/Off: Control the floodlight using the external wall switch or circuit breaker to which it is connected.
- Adjusting Angle: The integrated mounting bracket allows for a 150-degree adjustable angle. Loosen the screws on the side of the bracket, adjust the light to the desired angle, and then tighten the screws to secure it.

Maintenance
Regular maintenance ensures optimal performance and longevity of your floodlights.
- Cleaning: Periodically clean the surface of the light fixture with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the light is off and cool before cleaning.
- Inspection: Annually inspect the wiring and mounting for any signs of wear, damage, or loose connections. Address any issues promptly.
- Breather Valve: The floodlight features a unique breather valve designed to prevent moisture ingress and regulate internal pressure, contributing to its long lifespan. No specific maintenance is required for this valve.

Troubleshooting
If you encounter issues with your Ustellar LED Flood Light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on | No power supply Loose wiring connection Faulty light fixture | Check circuit breaker and wall switch. Verify all wiring connections are secure (ensure power is off first). If other solutions fail, contact customer support. |
| Light flickers | Unstable power supply Loose wiring connection | Ensure stable power source. Check and secure all wiring connections. |
| Reduced brightness | Dirt or debris on lens Aging LEDs | Clean the lens with a soft, damp cloth. LEDs have a long lifespan, but gradual degradation can occur over many years. |
If the problem persists after attempting these solutions, please contact Ustellar customer support.
