They'll do great. I have led in mine from them and they are plenty bright. The ones I have ordered will have it too.
I do like offering light. I'm just not convinced on the UV thing. It's a cost that hiding snakes are not utilizing in a way to be cost effective to me.
I wonder if the snakes actually became more lively or if they wanted to escape it. Say you have two identical cages connected with a tunnel. The only difference is one has UV. Which would they choose? If anything knows of testing like that I'd be interested in seeing it.
