Distributed lighting control systems are most commonly controlled by?

• A. Central control panel
• B. Computer server
• C. Device
• D. Building management system

Answer: (C)

In distributed lighting control, the control decisions are made by the individual control points themselves. Each lighting point or group carries its own logic—the local controller inside a dimmer switch, occupancy sensor, or fixture—so it can respond directly to input and preset scenes without waiting for a central dispatcher. This local intelligence lets lights operate independently, respond quickly to changes, and scale across large areas. A building management system or computer server can still monitor status and manage schedules, but in this setup they don’t perform the day-to-day control actions; the device itself handles that. That’s why the best answer is that control comes from the device.
