-For simple lighting I use a 13in LED bar that I got from Lowes, easy to mount, low energy consumption and lights up the cages nicely.

-For heating, some of my buddies that use Melamine (I do not) have cut an area out of the bottom where they wanted the heat pad to go and put in a piece of PVC sheet or plexi that is thinner and they put the pad under that so it will heat through.

-For bedding I am not a fan of that felt/carpet, it can hold too much bacteria and it doesn't allow your snake to burrow.
