Lighting control systems serve to provide the right amount of light where and when it is needed. ... Lighting control systems are employed to maximize the energy savings from the lighting system, satisfy building codes, or comply with green building and energy conservation programs.The most common form of lighting control today is a single switch or dimmer controlling a light or group of lights (a zone of lighting). While this historic standard certainly works, it is cumbersome relative to the ease of a lighting control system, especially in larger homes.
Think of the time and effort expended turning the lights on in the morning, off when you go to work, back on in the evening, and finally off again at bedtime. When you think of the quantity of the dimmers and switches that you need to walk around turning on and off throughout the day, the convenience of a lighting control system quickly becomes apparent.
