Here's a thread I started last year when my first BP ever (my Butter Pastel) did this exact same thing: http://ball-pythons.net/forums/showt...-Arboreal-Hide

My solution (post #33) was to put a bunch of crumpled up newspaper in the enclosure with her. It didn't take very long for her to come down on her own and tended to avoid the light after that.

A few months later when I got my Spinner Blast girl, she started doing the same thing - even with the newspaper. She eventually made a game out of knocking down the light when she got big enough to do so. After a few times of that, I made sure to tighten the screws as best as I could and she was only able to knock it down once a month instead of the every few days routine she started with. My solution to this? I called Ali up at Animal Plastics and ordered new tops without lights (not too expensive at all) so she couldn't sneak out the cord hole if I just removed the light. They shipped to me MUCH faster than a regular order with them and now I no longer have lights in either of my two T8s (and a second set of tops with lights for when I sell them in a month when my rack arrives).

I lived and I learned. I hope this helps!

Best regards,
