There is no difference in a fixture or the ballast for any T12 or T8 NO
bulbs. Shop light fixtures will take either one just fine, and the ballast
will start either one just fine.
Shop lights are cheap, and that is due mainly to the fact that they use
magnetic ballasts and cheap looking fixtures. If you don't mind the way
they look, then go for it.
If you decide that you want electronic ballasts, which have instant start,
can run the bulbs using less electricity, make the bulbs last longer, and
burn brighter in many cases--you can upgrade the ballasts. You may even
want to consider upgrading the whole fixture to improve looks.

I want the cheap ones that people hang in the shop and buy the
standard size, I saw some for $15 that will fit 2 bulbs. I
don't know what T size that is. But I saw in the store a plant
bulb with pictures of plants that looks standard size.

Thanks for the info.

You'll need to know a couple things. First see what diameter (T12, T8,
etc) bulbs your shop light fixture uses. This should be in the
docmentation for the fixture or you can ask the store where you bought
it.
Also see if it uses a magnetic or electronic ballast. This will determine
what kind of bulbs you can buy.
