So you're lighting with what, high-bay metal halide fixtures, but are
supplementing the workbench areas around the columns with fluorescent?

Not exactly an idle question - my comparatively tiny 24x48 foot shop is
not yet lighted, except by a lot of windows which I felt I needed, based
on disliking many windowless shops, as the slow construction process
with me as the builder drags on - some sketchy pictures and no
explanatory text at all at http://www.sover.net/~lsmith

Of course, I only have about 11-1/2 feet to the bottom of my joists, or
13 feet to the bottom of the floor on top of them if I mount lights
in-between the joists, so I don't know if high-bay fixtures are really
going to work. You must have 18-20 foot to the roof? Efficiency (power
in to light out) of lighting is going to matter quite a bit (power
company being jerks = off-grid), and I'm already hitting the point where
I need a lot of light, so "efficiency" masquerading as "not very much
light" won't cut it.

Tidy efficiency - a nice goal, A goal I do actually have, but this is
not yet even close:

If you are not going to insulate the ceiling, and even if you are,
yours looks like a natural for T8 fluorescent lighting with
electronic ballasts. I would think you don't have the ceiling
height for high pressure sodium or metal halides, to say nothing
of the expensive bulbs.

That ceiling is under the second floor (went with 20 inch TJIs so that
the second floor can actually hold some stuff - 56lbs/sq ft.,
clearspan), so no extensive insulation plans. The attic gets a lot of
insulation (and the walls are R-34 stress-skin panels).
