If I order two lights, do they space them out for the divider? And does the actual light bulb come with the set-up?

Thanks for all the help. You will have my two snakes living life like a boss. I'm going to go with the T8. The sooner the better for my BRB and her humidity needs. Will those thermostat's suffice on Amazon (the cheaper ones?). I'm already dropping close to $400 on this set-up now, and will eventually have to buy another one for the BRB when it out grows it's section....which brings me to my next question.

When it's time to take the divider out and give each snake their own set-up. Can the flexwatt belly heat be removed? Or is it a one time stick em type of deal like it is with the zoomed UTH? I'm asking because you said to place it in the middle for the two snakes in one tank w/divider.
