Hi all! I have two AGTFs in a 12x16x24 vivarium, and recently purchased a 12" fluorescent tube bulb holder. I haven't found any uvb bulbs that are 12" besides a Zoo Med Repti Sun 12" T5 5.0 High Output UVB Bulb on LLLreptile, but I'm not sure if this gives off too much UVB. Does anyone know whether I can use this bulb? Would compact uvbs be better? Thanks for any advice.
