I anticipate upgrading to a 30BR Zilla Critter Cage within the next few months since my boy is now at about 3 ft long and is living in a 20L with two Exo Terra Large reptile caves.

I've done well with the 20L keeping foil on the screen and an overhead infrared lamp. Cool spot/ambient runs 73-78 (night/day), heat mat keeps warm hide at 90-92. Humidity is always 55%-70%. He tends to favor his cool hide and I believe part of that is because the lamp is near the hide and I'm sure it absorbs some of the heat.

I was going to go with a similar setup for the 30BR, but with extra large Exo Terra reptile caves, and a larger heat mat. However, since the 30br is 6 inches longer and 6 inches wider, I am curious as to making sure the temps are up. I don't know what wattage lamp is there now, but I was thinking with the 30br I will need at least a 100w lamp.

Does anyone think I would need two lamps (one at each end)??

Thoughts and opinions are welcome.......
