Retile Basics 2x3 12 cage??

[CALM Pythons]

I am looking at the reptile basics 2x3 12 cage for my big girl, but have a few questions. How would you have a warm and cool side? Seems pretty dark, how would that affect the day/night cycle? There isn't much info on the cage. Guess I just need to understand this type of cage better.

I ordered a AP. Im waiting for it now but all these PVC enclosures seem to be what people are most happy with. I hell of a log eiser to maintain temps ect... I use one UTH and one RHP and some use one UTH and a Ceramic (CHE) for the ambiant cool side.
Once you think about it its easy useinh the UTH for a 90 degree basking hot side.
I use a Herpstat to adjust the amount of heat to my units but if money is a issue then use a cheap Dimmer switch for now and adjust the power going to your cool side...
Here is the AP enclosure. I paid $150 for the T8' 48"x24"x12" and $230 delivered but I added LED lights for $40.
