If you have a bp switch to a UTH. You may not be comfortable but it's better for your snake. They are no big deal. They are even better to control temps then a bulb. Is you tank just 80 or do you have a basking spot around 90 as well?
You don't need to wait 2 weeks. 1 is good. It will seem like a long wait but it's good for the snake. And don't over handle right away either once the week is up.
