5. Setup and Installation
This flood light is designed for hardwired installation. The recommended installation height is between 6.5 and 13.1 feet (2 to 4 meters) above the ground for optimal motion detection.
5.1 Installation Steps
- Prepare for Installation: Turn off power at the circuit breaker before starting. Ensure the mounting surface is secure and can support the fixture's weight.
- Attach Mounting Bracket: Secure the mounting bracket to the junction box (not included) using the provided machine screws. Ensure the bracket is oriented correctly.
- Wire Connections: Connect the household wiring to the fixture's wires using the provided wire nuts. Match the wires: black to black (Live), white to white (Neutral), and green/bare copper to green (Ground). Ensure all connections are secure.
- Seal and Mount Fixture: Place the silicone gasket over the mounting bracket to create a weather-tight seal. Align the fixture with the mounting bracket and secure it with the long machine screw.
- Adjust Light Heads and Sensor: Loosen the screws on the light heads and motion sensor to adjust their angles as desired. Tighten the screws once adjusted.
- Restore Power: Turn on power at the circuit breaker.

6. Operating Modes and Adjustments
The Onforu flood light offers multiple operating modes and adjustable settings to suit your needs.
6.1 Operating Modes
- Motion-Activated Mode: The light turns on when motion is detected within its range and angle. It remains on for a set duration and then turns off if no further motion is detected. This mode supports dimming.
- Dusk to Dawn (D2D) Mode: The light automatically turns on at dusk and turns off at dawn, providing continuous illumination throughout the night.
- Test Mode: An initial test mode allows you to confirm the light's functionality. In this mode, the light will turn on for 5 seconds when motion is detected, regardless of ambient light conditions (day or night).

6.2 Adjustments
The motion sensor typically features rotary switches or buttons for adjustment. Refer to the labels on your specific unit for precise control.
- TIME (Timer): Adjusts the duration the light stays on after motion is detected. Settings typically range from 10 seconds to 10 minutes.
- SENS (Sensitivity/Detection Distance): Controls the motion sensor's sensitivity, affecting the detection range (20 to 72 feet). Higher sensitivity detects motion further away.
- LUX (Ambient Light Sensor): Determines the ambient light level at which the motion sensor becomes active. Set to 'Sun' for day and night operation, or 'Moon' for night-only operation. This also controls the Dusk to Dawn mode.
- DIMMING: (Applicable in Motion-Activated Mode) Allows adjustment of the light's brightness from 10% to 100%. Note: If the brightness is set between 10% and 30% in motion-activated mode, the light may remain on all night at the dimmed level.

7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your flood light.
- Cleaning: Periodically clean the light fixture and motion sensor lens with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or electronic components.
- Inspection: Annually inspect the wiring and connections for any signs of wear, fraying, or corrosion. Ensure all mounting screws are tight.
- Obstructions: Ensure there are no new obstructions (e.g., growing foliage, new structures) blocking the motion sensor's field of view.
8. Troubleshooting
If you encounter issues with your Onforu flood light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on | No power; incorrect wiring; LUX setting too high (daylight); sensor obstructed. | Check circuit breaker; verify wiring connections; adjust LUX setting; clear sensor path. |
| Light stays on continuously | TIME setting too long; continuous motion in detection zone; DIMMING set to 10-30% in motion mode. | Adjust TIME setting; remove motion sources; adjust DIMMING setting or switch to D2D mode. |
| Light turns on during the day | LUX setting too low (towards 'Sun'); Test Mode active. | Adjust LUX setting towards 'Moon'; ensure Test Mode is not active. |
| Motion not detected | SENS setting too low; sensor obstructed; incorrect sensor angle. | Increase SENS setting; clear obstructions; adjust sensor angle. |
| Light flickers | Loose wiring connection; unstable power supply. | Check and secure all wiring connections; consult an electrician if power supply is unstable. |
