Using T10 bulbs in T8 Fixture?

I just bought a triple tube all glass strip light which says it is for T8 lights, but I could only find T10's at my LFS. The T10's work fine in it, but it is a tight fit. Is there any danger to using T10's in a T8 fixture? Or is the only difference the diameter of the bulbs?

Edit: I just answered my question the T stands for tubular and the number stands for the diameter of the lamp in eights of an inch. explains it in a little more detail. As far as i can tell there's no harm in what I'm doing, but if anyone knows otherwise please let me know.

The pin size will fit the same quality mounting plates but as far as I can tell, T8 ballasts are lower voltage than those used for T10 and T12 . This will give poor quality light from a T10 if they work at all.

Try Home Depot, Walmart or some other home improvment location to find T8 bulbs. They should be fairlty easy to find there.
