Which of the following is NOT included in a typical planned maintenance program?

In a typical planned maintenance program, the focus is on preventive actions that help to sustain the performance and longevity of lighting systems. Periodic group relamping, periodic luminaire cleaning, and troubleshooting are all activities aimed at maintaining optimal functioning, addressing issues before they lead to failures, and ensuring clean and efficient light output.

Periodic luminaire replacement, however, is not typically included as part of standard planned maintenance practices. This process is often reactive rather than proactive, signifying the end of the life expectancy of a luminaire rather than a regular maintenance task aimed at prolonging its life. Such replacements might occur intermittently or as part of a larger upgrade plan rather than on a set schedule as seen in regular maintenance tasks. Thus, it stands apart from the ongoing maintenance efforts that characterize a robust planned maintenance program.
