Thanks all! After reading your comments; I went along and moved him around to where I wanted to put him! It fits in PERFECTLY!
Yeah, as with the sun, even up the other end where he was (because my room is always very sunny during the day) I've been covering his enclosure with an old horse blanket I've had since I was 4 (to keep sun out, but will now be used to prevent heat as well). It's never been used and I always kept it in the draw because I really loved it. Finally found a use and it gives him a lot of darkness during the day!

The lights around his cage are battery powered, not electric powered!
