So I finally ordered a cage from AP, it's 36x24x15. I will have two light fixtures in there (one for day and one for night). Now I need to find a black light night bulb that will fit into one of the fixtures. I believe it takes 18 in bulbs, but I may be wrong.

Does anyone know where a can find something like this, that is specifically for reptiles(or at least safe for reptiles)?

Or... if anyone knows the length of the light bulbs for the fixtures from AP please let me know, since I'm not positive on the length.
