6. Operating Instructions
The BGS P2 LED Security Light features adjustable color temperature and an integrated dusk-to-dawn photocell.
Color Temperature Adjustment:
The fixture has a dial on the back that allows you to select one of three color temperatures:
- 3000K: Warm White
- 4000K: Cool White
- 5000K: Daylight
Rotate the outer dial to the desired color temperature setting. It is recommended to choose a warmer color temperature (e.g., 3000K) for outdoor use to minimize disruption to wildlife, as 5000K is very close to natural daylight.
Photocell Operation:
The integrated photocell automatically turns the light on when ambient light levels drop (dusk) and off when light levels rise (dawn).
- Sensitivity Adjustment: An inner dial allows you to adjust the photocell's sensitivity. Turning the dial towards the blue indicator makes the sensor more sensitive, causing the light to turn on earlier in the evening. Turning it towards the yellow indicator makes it less sensitive, causing it to turn on later.
- Manual Control: To bypass the photocell for manual control (e.g., with a timer or wall switch), rotate the inner dial to the position indicated by the blue dot. This effectively tells the light it's always dark, allowing external controls to manage its operation.

- Inspection: Periodically inspect the fixture for any signs of damage, loose connections, or wear. Address any issues promptly to ensure continued safe and optimal operation.
8. Troubleshooting
| Problem | Possible Cause | Solution |
