I have a 4 foot long shop light,Its 2 fluro tubes.I want to cool it down,It gets hot beleive it or not,question is what part gets hot?I thought about running a home made water cooler to a resevoir.I just dont know wich part of the light gets really hot..Im guessing the bulb lol.So is there an easy way to air cool this unit with MINIMAL noise?any ideas are greatly appreciated.
