Operating Instructions
Dusk to Dawn Mode
The flood light is equipped with a built-in photocell sensor. In this mode, the light will automatically turn on when ambient light levels drop (at dusk) and turn off when ambient light levels rise (at dawn). This mode is active by default.

This image illustrates the automatic dusk-to-dawn functionality, where the light activates at night and deactivates at dawn using its integrated sensor.
Switch Controlled Mode
To operate the light manually via a wall switch, cover the photocell sensor with the provided silicone cap. Once the sensor is covered, the light will respond to the connected wall switch, allowing you to turn it on or off as needed, regardless of ambient light conditions.

This image demonstrates how to switch from dusk-to-dawn mode to manual switch control by covering the photocell sensor with the provided silicone cap.
Maintenance
- Cleaning: Periodically clean the fixture with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.
- Inspection: Regularly inspect the fixture for any signs of damage, loose wiring, or wear. Address any issues promptly to ensure safe operation.
- Photocell Sensor: Keep the photocell sensor clean and free from obstructions (e.g., dirt, leaves) to ensure proper dusk-to-dawn functionality.
