What is standby lighting?

What is standby lighting?

• A. Emergency lighting to allow normal activities to continue if the normal lighting supply fails
• B. Decorative lighting
• C. Lighting for standby rooms
• D. Lighting used only during power outages for long durations

Answer: (A)

Standby lighting is the illumination kept in place so people can continue working when the main lighting loses power. It is meant to let normal activities proceed during a power outage, supporting ongoing tasks or processes rather than merely lighting a path for evacuation. Decorative lighting serves aesthetics, and lighting for standby rooms isn’t about maintaining operation during a power loss. Standby lighting isn’t about long-duration outages; it’s intended to bridge short interruptions until power returns. The option describing emergency lighting that allows normal activities to continue when the main supply fails matches this function.
