You have a couple of choices: An array of lights all over the room
that are turned on simultaneously, or groups of fixtures that cover a
particular area. Here are some suggestions:

1. Put a 2-bulb, 4-foot, 34/40-watt fixture over each workbench so you
have strong lighting for fine work.

2. Put another over the table saw, bandsaw, jointer, belt/drum
sander, and sanding table, as applicable.

3. For general lighting, based on 30 x 40 feet, about 6-9 fixtures
in a 2 x 3 or 3 x 3 array would work nicely for general lighting.

There are no right or wrong answers. Lighting should be arranged to
fit your "style" and interests. 4-foot, 2-light fixtures are cheaper
to buy because they're a lot more common.

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?
