It is very easy. Just get a fluorescent light fixture that can be mounted to a wall/ceiling with screws. Then mark where you want the light, then stick some screws in. The hardest part will be drilling a hole large enough to get the cord out... While still preventing the snake from being able to get out.
I was thinking that 2. Maybe I could drill the hole and have the light covering the hole by having the cord kinda bend around towards the middle of the light.
This is how I see it, a ball python will live for 20+ years. I'd rather spend a little more now and by happier with my cages than save a few $$ now and either spend more later or have to rig things to get them the way that I want.
Also if AP is going to a show near you they will bring the cage with them and you don't have to pay for shipping
*I don't know what shows they go to and you have to order the cage in advance do they can have time to make it before the show.
