ABout 120 lumens per sq ft should be plenty blinding

Depends on what you're doing/storing in there along with color of walls and ceilings.

The lights should be adequate. You'd get a lot more light by painting the walls though.

If you're wiring an open ceiling, its a very minimal extra to prep for a 3rd row in the center. If you don't need it great, a few extra feet of romex is there, imo less than the cost of 1 fixture. But if you do need it, its just plug and play or complete the hardwiring below the ceiling.
I put 10 of the costco 42W twin tube LED fixtures in my shop and its quite bright already. Wiring is in place for 10 more as the budget allows.

Agree completely. Wire up for extra (it's cheap insurance) and wire it such that you can switch on what you need when you need it.

Oldno3fan,
That's way overkill for that space, but if I recall, you have a vision issue, correct? If so, and if you are going to spend tons of time in the space, I'd ask your doctor about the effects of heavy blue wavelength light over extended periods of time.
A different solution would be T8 or T5HO fluorescent. Not nearly as efficient as the LED, but not so heavy in blue wavelength. And you can still get the 5000k color you want.
Another solution would be to back off the overkill on the general illumination and to focus on maximizing your light in the work areas with task lighting.
No. It doesn't work that way. Lumens per square foot means nothing.
Good luck

CD, can you elaborate or post some links so I can read about the long term blue wavelength issue? For instance wouldn't using a lot of natural sunlight through skylights and big windows mean using high Kelvin light?
Reason I ask is I will soon be choosing fixtures for my shop. Currently have three test fixtures up, one each using 4100, 5000, and 6500 K and I seem to like the 5000 best. But I don't want to make a mistake since I will be using the shop a good bit as I will be retiring.

You haven't defined your requirements so it's hard for anyone to say "it'll be enough". Do you want 50 FC or 100FC or what? How are your eyes? How old are you and are you planning to be in this space for long? What are you doing in this space?
Personally I overbuilt as my eyes aren't as young as they used to be. I built to 100FC but have it arranged so I can turn off lights if what I'm doing doesn't need that much.
Here's a tool I used, and while there are experts on this forum that can do the calculations themselves (and possibly more accurate), I found the tool to be helpful:

As well, this article helped to put it all in perspective (ie. FC, Lumens, coverage, Lux, etc...):

I'm not saying these are the definitive tools/information to use as I'm sure there are others that know better, but they worked well for me.
Cheers.

Good links with great info!! The calcs on the second link suggest that I need 35 fixtures for my 650 sqft garage at 100fc and a loss of 50% with the costco 3700 luman fixtures. Seems a bit excessive. I was thinking 12-16 would be pretty bright. Do my calculations make sense? I'm thinking maybe the 3700 figure could mean PER row which would actually be 7400 lumans per fixture. If that's true then my wild guess of 12-16 would jive with actual math!
On the first link, which is also pretty neat, any suggestions on a particular lamp that would represent the costco fixtures without having to go through each one, comparing specs?
For reference: Costco Fixtures
Cheers!

Sorry B-dog, I'm going to have to defer on the tech questions! When I did my calculations, I found a standard T8 fixture in the library and just used that. I may have even asked the board for a recommendation (did it a long time ago if I did). As for losses, that will of course vary by fixture/lamp/etc...so figuring 50% loss may be a bit much (I don't recall using that much and with LED, I think the loss factor is less although one of the experts here will need to confirm/refute that).
Cheers.

Twelve fixtures will be plenty for your garage but why spend that kind of money when you can get these:

Cool, thanks for the reassurance. I'll start with what I originally thought, I could always add more later if i had to.
I'm not sure if you saw, the ones in my link is actually a quantity of 2 so the cost difference isn't that much but they use 1/3 less energy.
