Not to derail this thread, but I don't want the OP to have incorrect information. Toad37, look it up on on ANY reliable reptile site or care sheet and they will all recommend the same thing: 90 degree hot spot max for BP's. Your temps are way too hot. I use infrared heat lamps in conjunction with heat mats for ambient temperature purposes, and I don't go over 75 watts but they are all dialed down on dimmers. 100 watts at max power in a 20L...![]()
