Which term best describes a lighting control approach where decisions are made at local devices rather than a central controller?

• A. Centralized
• B. Distributed
• C. Standalone
• D. Networked

Answer: (B)

Decisions are made at local devices rather than a central controller, describing distributed lighting control. Local controllers evaluate inputs from sensors (like occupancy or daylight) and set lighting levels on the spot, so responses are fast and don't depend on communicating with a central brain. This setup also increases reliability because there's no single point of failure, and it scales well as you add more zones or fixtures. In contrast, centralized means one main controller makes all decisions, standalone means devices operate without coordination, and networked focuses on connectivity rather than where decisions are made. So the best term for this approach is distributed.
