Why don't people use water cooled lights?
I have used mine for 2 years with no problems. But I'm very careful. The problems are loss of light 14% in some of my tests, humidity is still a problem even if you solve your heat problem. This is assuming your in a sealed room.
Light is everything so bare bulbs is the best way to go, your going to need A/C or dehuey even if heat is under control.
Will be using my water cooled rig for a tent with my mothers and clones in the future.
