Dumeril or RTB?

I have been looking into these for about a week would you go with the 40 watt or 80?
and what about light?

That's going to depend a bit on how warm your home/room is and how high the cage is. For a 4 ft long cage, if you go with only a 12" high cage, the 40 watt is probably enough. If you go with a 24" high, then I'd do the 80 watt. If you go with the 18", then look at the room temps and see. If in doubt, I would err on the side of caution and use the smaller wattage - these panels heat very efficiently.

I don't use a light with my boas. My GTP has a light, but mainly for my convenience - I like to see him! But the snakes really don't need the light.
