6. Operating Instructions
6.1. Dusk-to-Dawn Functionality
The Paktonvo LED Barn Light is equipped with a built-in photocell sensor. This sensor detects ambient light levels and automatically controls the light's operation:
- The light will automatically turn ON when the ambient light level drops (at dusk or night).
- The light will automatically turn OFF when the ambient light level rises (at dawn or daytime).
Ensure the photocell sensor is not obstructed by objects, dirt, or other light sources, as this can interfere with its proper operation.
