QRB1A-A150B70A LANDIS & GYR LOA24 CONTROL BOX

A sensor that detects ambient light levels and automatically controls lighting systems. When light levels fall below a certain threshold, the photocell triggers the lights to turn on, and when the light levels rise again, it prompts the lights to turn off. This functionality helps save energy by ensuring that lights are only used when needed, making it ideal for outdoor lighting applications and energy-efficient building designs.
