I just wanted to know what everyone's opinion is of using a heat light. Since some people use one, some people don't, I figured there must be several different opinions.

I'm going to be getting my first ball tomorrow. (not my first reptile or snake, just never had a ball python) For all snakes I've always just used a UTH, no lights. It seems that for balls there are a lot of people that use a heat lamp but then probably equally as many that don't. Is it necessary and/or beneficial to the animal? Why or why not?
