It depends on the ballast. First, how long are the bulbs currently in there? You shouldn't try to fit wattage to wattage but diameter and length should be checked. The diameter is the T5, T8, T12. T5 being 1/2", T8 I believe 3/4" and T12 1" in diameter. Second, I have only seen Geissman bulbs in T5 sizes, although I haven't really looked at them much for other sizes. I know UVL makes T12 bulbs, not sure on the other manufacturers. Let me know on the length and diameter, and we can help you out much more.

 

T5 are 5/8", T8 are 1" and T12 are 1.5".

 

Oopps, thanks for the correction.

 

Figuring out and remembering the designation is a PITA.
