Setup and Installation
Follow these steps for proper installation of your security light:
- Prepare for Installation:
- Turn off power at the circuit breaker or fuse box to the junction box where the light will be installed.
- Ensure the mounting surface is clean, dry, and structurally sound.
- Mounting the Fixture:
- Attach the mounting plate (if separate) to the junction box using the provided screws.
- Feed the electrical wires from the junction box through the center hole of the mounting plate.

- Wiring Connections:
- Connect the black wire from the fixture to the black (hot) wire from the junction box using a wire nut.
- Connect the white wire from the fixture to the white (neutral) wire from the junction box using a wire nut.
- Connect the green (or bare copper) ground wire from the fixture to the ground wire from the junction box using a wire nut.
- Carefully tuck all wires into the junction box.

- Secure the Fixture:
- Align the fixture with the mounting plate and secure it with the provided screws. Ensure a tight seal against the mounting surface to prevent water intrusion.
- Adjust Light Heads:
- Loosen the adjustment screws on the light heads and pivot them to the desired angle for optimal illumination coverage. Tighten screws firmly once adjusted.
- Restore Power:
- Turn power back on at the circuit breaker.
Operating Instructions
Your Westgate LED Security Light features adjustable settings for color temperature, motion sensor sensitivity, and time duration.
1. Color Temperature Selection (MCT)
The fixture allows you to select between three color temperatures: 3000K, 4000K, and 5000K. The switch for this selection is located on the bottom of the base, typically near the motion sensor.
- 3000K: Warm White, ideal for a cozy, inviting ambiance.
- 4000K: Cool White, a neutral white light suitable for general outdoor illumination.
- 5000K: Daylight, a bright, crisp white light for maximum visibility and security.
To change the color temperature, locate the small switch on the underside of the fixture's base and slide it to your desired setting (3K, 4K, or 5K).
2. Motion Sensor Adjustments
The PIR motion sensor has adjustable dials, usually located on the bottom of the sensor unit. These typically control LUX (light sensitivity), TIME (duration), and SENS (motion sensitivity).
- LUX (Light Sensitivity):
- Adjusts the ambient light level at which the sensor will activate the light.
- Turn towards the "sun" icon for activation during both day and night.
- Turn towards the "moon" icon for activation only during low light conditions (dusk to dawn).
- TIME (Duration):
- Sets how long the light remains on after motion is detected and no further motion is sensed.
- Typically adjustable from a few seconds to several minutes.
- SENS (Motion Sensitivity):
- Controls the detection range of the motion sensor.
- Turn clockwise to increase sensitivity and detection range (up to 68 feet).
- Turn counter-clockwise to decrease sensitivity and detection range (down to 19 feet).
- Note: Maximum sensitivity may cause false triggering from small animals or distant objects.

Maintenance
The Westgate LED Security Light is designed for minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Periodically clean the fixture with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or lens. Ensure power is off before cleaning.
- Inspection: Regularly inspect the fixture for any signs of damage, loose wiring, or wear. Address any issues promptly.
- Lens: Keep the polycarbonate lens clear of dirt, dust, and debris to maintain optimal light output and motion sensor performance.
Troubleshooting
If you experience issues with your security light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power; faulty wiring; sensor set to "moon" and it's daytime; sensor malfunction. | Check circuit breaker. Verify wiring connections. Adjust LUX setting towards "sun" icon for testing. Contact support if issues persist. |
| Light stays on continuously. | Sensor set to test mode; continuous motion in detection zone; faulty sensor. | Check sensor mode. Clear detection zone of obstructions. Adjust SENS setting. |
| Light turns on and off frequently. | Sensor too sensitive; interference from heat sources (e.g., vents, reflective surfaces). | Reduce SENS setting. Reposition fixture or remove interfering objects. |
| Detection range is too short/long. | SENS setting incorrect; obstructions. | Adjust SENS dial. Ensure clear line of sight for the sensor. |
