My shop is about the same size as yours and I have dual lamp 8' T8's in my
shop and have them spaced about 6 feet apart in all directions. My ceiling
is 14 feet fwiw.

I am getting close to wiring my new shop. It roughly 30 x 40 with 9 foot
ceilings. It a daylight basement but I have a minimum of windows. The shop
ended up more below grade that I expected. My plan once we get it dried in
to paint the walls white to lighten it up. Then install T8 fluorescent
lighting. I am going to look at 8' and 4' fixtures and compare prices to
see
which is the better deal.

But my question is spacing and how many fixtures? I read somewhere to use
single bulb fixtures spaced at 4 feet. But so far that is all I have
found.
Search the web a good bit tonight and found nothing. Anyone know of a good
reference on this?
