What you want to buy are lumens delivered on the surface you want to light.

By definition, one lumen per square foot = one foot candle.

What you pay for is KWH of electricity.

The lighting system converts KWH of electricity into lumens.

Well, as long as we're on the subject of lighting, I'm gonna take a
shot at butting in.

I'm also looking to light a shop (24 X 25 X 8' ceiling), and in
reading an article on workshop lighting, it suggested 80-100 fc for
old fogies (40+) like myself for a woodworking shop.

So, while I know there are probably 50 variables including the paint
color, machines, etc., how do I (even ballpark) get from KWH (or
wattage) to foot candles? Basically, after reading the article I know
I want "lots of light," but I still have no clue how to convert "lots
of light" into X-number of 2-bulb, 4' fixtures. Any suggestions on
how to make the conversion?

Thanks,

Ricky
