I just ordered the change from Safelight Jumbos to safelight Jrs. Hopefully that should have a difference with the lower wattage. My darkroom is a fully enclosed (including ceiling) room built within the garage only using 1 exterior garage wall. The rest of the walls are all insulated and finished on the outside, so there are no leaks. All leaks were calked/taped up immediately after construction. The ext garage wall has a hole for the AC, but that's been taken care of as well.
Hopefully this is all that'll need to be done, and as soon as the new safelights arrive, I'll let everybody know.
Thanks for everyone's help. + HNY
