When I bought the heat pad at the reptile expo, the guy who sold it to me who has been selling them for years said that it would be fine, the newer ones would not get that hot. I have him in a exo terra medium low and was going to put foil or clear wrap on top of his cage. Someone suggested Reflectix to fis that issue. I have a spray bottle and I'm spraying the tank once a day. Tomorrow I'll find out just how humid the cage is.
