Setup and Installation
The Defiant LED Motion Security Light is designed for quick and safe installation. Follow these steps carefully:
- Step 1: Prepare Wiring
Ensure power is turned off at the circuit breaker. Connect the house wiring to the mounting plate. The mounting plate contains the electrical connections. - Step 2: Mount Base Plate
Secure the base plate to the junction box on your wall or eave. Ensure the wiring is properly connected and secured within the base plate. - Step 3: Attach Light Fixture
Align the main light housing with the base plate. The electrical prongs on the light fixture will plug into the base plate. Secure the light fixture to the base plate.

Operating Instructions
The Defiant LED Motion Security Light features adjustable settings for optimal performance.
DualBrite Technology
DualBrite allows the light to operate at a low accent level from dusk-to-dawn, providing continuous subtle illumination. When motion is detected within its range, the light will automatically switch to full brightness for a set duration, then return to the accent level.
Motion Sensor Adjustment
The motion sensor can be adjusted to control sensitivity and the duration the light stays on after motion is detected. The selectable "ON" duration timer offers manual override options (test, 1, 5, or 20 minutes).
- Sensitivity: Adjust the sensor head to cover the desired detection area.
- Time Setting: Use the control dial on the sensor to set how long the light remains at full brightness after motion stops.

Maintenance
The Defiant LED Motion Security Light requires minimal maintenance.
- Cleaning: Periodically wipe the light fixture and sensor lens with a soft, damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the wiring and mounting for any signs of wear or damage. Ensure all connections remain secure.
- LEDs: The integrated LED bulbs are designed for long life and do not require replacement.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power; faulty wiring; sensor obstructed. | Check circuit breaker. Verify wiring connections. Clear any obstructions from the sensor. |
| Light stays on continuously. | Sensor sensitivity too high; continuous motion in detection area. | Adjust sensor sensitivity. Ensure no constant motion sources (e.g., tree branches) are in the detection zone. |
| Light flashes or flickers. | Loose wiring connection; power fluctuations. | Check and secure all wiring connections. Consult an electrician if power fluctuations are suspected. |
| Motion detection range is poor. | Sensor angle incorrect; obstructions. | Adjust the sensor head to optimize coverage. Remove any objects blocking the sensor's view. |
