Trust me the lamps not going anywhere in the tank, especially w/ water being misted. Wouldn,t want this guy to get burned, and second I am of the sound opinion water and anything electric are bad beans when combined. We try to keep general thoughtlessness out of the house and common sense in. These bulbs produce a lot of heat. Regarding the bulbs though, the ceramic is used cue to the high temp of the bulb, correct? Is this the mane reason for cerramic fixtures over anyother type, or are there other reasons?
