Distributed lighting control systems are most commonly controlled by what?

Distributed lighting control systems are most commonly controlled by what?

• A. Device
• B. Sensor
• C. Controller
• D. Central switch

Answer: (A)

Distributed lighting control relies on local intelligence at each fixture or zone. In this setup, the device itself handles sensing, decision-making, and actuation, so lighting responds automatically based on occupancy, daylight, or other inputs at that location without needing a separate central point. A sensor alone only provides data; a central switch implies centralized control, which goes against the distributed approach. The device, meaning the fixture or control unit with built-in logic, is the typical control point in these systems because it can directly interpret inputs and adjust the lighting right where it’s needed.
