ETC Source 4 (S4) 575w fixtures
Ceiling Cove = 6ft x 1.5ft x 2.5ft (L x W x H)
Air conditioned room year round.
The current coves have a grate that opens to the attic. Venue wants to close that off so that the attic heat doesn't get into the room.
Concerned that the increase in ambient temperature (can't escape to attic) will decrease the life of the lamp.
ETC says best practice is to have constant airflow to "increase the life of the lamp" though they have no study to support this claim.
My problem with thinking ambient temperature determines life of lamp is that the ambient temperature is so small compared to the temp of the lamp as to be inconsequential. https://what-if.xkcd.com/155/
