Hopefully a simple lighting question!?

[mishelly58]

Ok I'm building a 3'X2'X2' viv for a friend's son. She wants to use a Repti-Sun tube light. The question I have is since I have to buy a light fixture I'm not sure what size I should get (I have a MVB in mine).

Should I get a 24" fixture and run it most of the length of the viv with a basking spot light on one side?

Should I get a 18" fixture and have a basking light next to it and then a regular light on the other end?
or
Should I get 2-18" in one the Repti-Sun and the other just a reg fluorescent in the other and a basking light next to the Repti-sun?

I want to pick up the fixtures and order the Repti-Sun tube soon.

Thanks for all your help!

I would go with the 24" fixture. Although it's only required to have at least half the viv covered with a UVB tube, I recommend most of the viv.
