You're right that the term "T-8" refers to Tube and a diameter of eight
1/8-inches, aka a 1-inch diameter tube. T-12 would be a Tube with a
diameter of twelve 1/8 inches, or 1-1/2 inch diameter.

I didn't read the post you refer to. Could the person be talking about
something else--CRI, Kelvin, spectrum, ...?
