The older I get, the more light I seem to need. My shop is 26x36 and I have 8 8' flourescents, 2 bulbs each. the paint is untinted white.
My old shop had the same set-up only I used magnetic ballasts. You couldn't hear yourself think in there. Electonic ballasts take care of the noise and the temperature issues. More expensive but well worth it.
As others have said, your can't have too much light. Opening skylights would be a real plus.

Let there be light!
