Not to bring up another lighting UVB thread etc. BUT I was wondering... are mercury vapor bulbs designed for more desert torts and reptiles than redfoots? Since they are so bright, is the issue of too much UVB into the tortoise's eyes hold true? This IS NOT a "whether you need UVB or not" thread, but one asking if it is DANGEROUS to use mercury vapor bulb's with redfoots, and if mercury vapor bulbs in specific are overkill...
thanks
