its about choice for you cyclura. If the ig wants to get higher temps it can. Of course your lizard will bask at 110-115 thats all you are giving it. They dont bask all day. if yours do its because they have to and the temps are too low. The point is to give them the heat range they need when they want it. you are deciding 115 is good enough, I think you should let the lizard decide, higher temps allows them to do that.
