As far as the T5/T8 debate goes, the T5's are a bit more expensive where the T8's can be used in any normal household fixture. The one benefit of the T5 over the T8 though is if you are putting it over the mesh top of your tank the T5 penetrates the mesh more and thus your dragon doesn't have to get as close to the UVB to reap the benefits. If you are mounting a T8 fixture on the inside of your tank then that bulb is going to be just fine. If you are resting the fixture on top of the mesh top, the T8 bulbs need to be replaced every 6 months or so, with the T5 you can get closer to 12 months with them. So in that case if you factor in the cost of a new bulb every 6 months (in some cases less) then the extra money up front for the T5 isn't so bad.
