NALMCO Certified Apprentice Lighting Technician (CALT) Practice Exam

Which of the following is NOT considered a benefit of group relamping?

1. Replacement labor savings

2. Consistent light levels

3. More luminaires can be installed

4. Opportunity to replace lamps with energy-efficient lamps

The correct answer is: More luminaires can be installed

The option indicating that "more luminaires can be installed" is not considered a benefit of group relamping because this practice primarily focuses on the replacement of existing lamps rather than the addition of new fixtures. Group relamping is about systematically changing out lamps in installed luminaires to maintain or enhance lighting quality, improve energy efficiency, and ensure uniform light levels across a space. The other choices all represent direct benefits of group relamping. Replacement labor savings occur during group relamping because technicians can efficiently replace multiple lamps at once, rather than addressing each lamp individually over time. This method is also beneficial for maintaining consistent light levels, as replacing all lamps simultaneously minimizes the differences in illumination due to varying lamp ages. Additionally, group relamping provides the opportunity to replace older, less efficient lamps with energy-efficient options, thus enhancing energy savings and reducing operational costs. In summary, while the other options highlight key advantages of group relamping focused on maintenance, efficiency, and consistency, the incorrect option pertains to the installation of additional luminaires, which falls outside the scope of the intended benefits of this practice.
