Corridor dimming is a lighting system feature that automatically adjusts the brightness of lights in hallways, stairways and other public areas. This feature helps conserve energy when the area is not in use, while providing a safe, well-lit environment when needed. By using motion sensors and timers, the lights automatically dim to a lower level when no one is present, and then brighten when someone enters the area. This feature helps to reduce energy costs, while still providing the necessary level of safety and security.
