I'm in the same boat as you EWC88. My T8 got here yesterday (minus the doors, lock and divider). I have decided to go with two 40w RHP's for my T8 since I'll be using it with a divider, and may have a snake on each side of it. If i end up using it for only one snake down the road, I'll just adjust the RHP's according to create a temperature gradient. I have some heat tape I can use if needed, but I may try it with just the RHP's and see how it goes.
