Operating Instructions
The JULLISON 6 Inch LED Low Profile Disk Light is designed for automatic operation thanks to its integrated Dusk to Dawn sensor.
- Dusk to Dawn Sensor: The built-in photocell sensor detects ambient light levels. The light will automatically turn on when the environment becomes dark (dusk) and turn off when sufficient light is detected (dawn). This feature ensures energy efficiency and hands-free operation.
