Why is group relamping a good idea?

1. Can raise light levels

2. Economizes on labor

3. Both (a) and (b)

4. None of the above

The correct answer is: Both (a) and (b)

Group relamping is considered a good idea primarily because it combines advantages that yield both operational efficiency and improved lighting quality. When all lamps in a specific area or system are replaced at the same time—rather than on a piecemeal basis—it can lead to noticeably higher and more consistent light levels. This is significant because, as lamps age, their light output diminishes. By replacing them collectively, you ensure that all lights are at their optimal performance, thus enhancing visibility and overall lighting quality in the environment. Additionally, from a labor perspective, group relamping economizes on labor costs. Instead of scheduling multiple individual maintenance visits for each lamp replacement over time, performing relamping as a single project reduces the time technicians spend on-site and minimizes interruptions to normal operations. This method streamlines the maintenance process, making it more efficient and cost-effective. These combined benefits of improved light levels and reduced labor costs highlight why group relamping is a strategic approach in lighting maintenance.
