What is the difference between T8, T10, and T12 fluorescent tubes?
I’m ordering fluorescent tubes, and I see that there are T8, T10, T12, and others. I figured they were different sizes, but then I saw, for example, that you can get medium bi-pin 48 tubes in both T10 and T12. What does T mean? Thanks
And is F anything important? As in F20, F40.

An inch 10 and 12 are sometimes interchangable on the same ballast.
