Which statement best describes group relamping?

• A. Replacing multiple lamps on a schedule to maintain lighting levels
• B. Replacing a single lamp as it burns out
• C. Painting fixtures white
• D. Installing motion sensors

Answer: (A)

Group relamping is the proactive maintenance practice of replacing several lamps on a planned schedule to keep lighting levels consistent and prevent noticeable dimming. It focuses on maintaining uniform illumination across fixtures by renewing a batch of lamps before they fail, which reduces maintenance calls and sudden drops in brightness. Replacing a single lamp as it burns out is reactive maintenance and can lead to uneven light levels. Painting fixtures white or installing motion sensors address other aspects of lighting efficiency or aesthetics, but they do not describe replacing lamps on a planned schedule.
