seems like the heat panels are the way togo.

i think i am going to go with the AP T8 48 x 24 x 12
my room temp is on average 73 (highest) day and 69 (lowest) night
do i need a 40 watt or 80 watt panel?
Thanks Kirk

RBI's FAQ
Which size do I need?


We have tested the 40 watt panel in several 2'x4' cage designs including our own PVC and various thicknesses of plywood. Participants in this test have also included ARBREPTILES (Clay Davenport), Boamaster (Mark Venhorst) and other private breeders. We have all reached pretty much the same guidelines.

In a 2x4 cage that is 12" tall or less in a room temp of 75° F+ you will see good results with the 40 watt RHP. The taller the cage the more likely you will want to set up basking sites that are elevated and closer to the RHP to give your animals a gradient. Generally taller cages 18" or taller are set up for arboreal use so this is not a problem. If your room temp is lower than 74 F or your cage is 12"+ you may want to move up to the 80 watt.
