also lets building owners take advantage of economies of scale by ordering more lamps at once and allowing crews to set up for one large project instead of multiple small ones.
Because similar LED products in an installation can be expected to reach end of life at approximately the same time, ideally they will be replaced all together--essentially group relamping
. This brings up two questions: What is actually being replaced?
If group relamping
was occurring as per IES recommendations, Fig.
To keep lamps, such as metal halides, working properly and to reduce the need for rampant spot relamping, some experts recommend a preemptive process called "group relamping
." When lamps are maintained using group relamping
, all lamps are replaced at the same time.

It may be time to take up group relamping
, a proactive maintenance strategy.
Ancillary Materials Costs, The group relamping
of the incandescents for the yellow, green, and white are included in the total retrofit activity.
However, changing your approach to group relamping
ultimately saves you more money.
Participants will become fluent in financial measures and learn sales tools to analyze retrofit options, design simple lighting layouts, suggest group relamping
schedules, estimate environmental impact and calculate demand reduction and utility rebates.
* We support the IES recommended practice of group relamping
at 70 percent of average rated lamp life, which also implies the need to deliver the target illuminance through 70 percent of rated lamp life [7, pg.
Then, the fixtures can be periodically cleaned on a schedule, typically during group relamping
