WOW, that is awesome ^^^ Thanks so much Svend! Very much appreciate the effort and I will post up some pictures as soon as it's done 
roadrunner - I experimented with multiple fixture and layout options and turns out the best one was the first one. The Cooper fixture you linked to is a good price for a good fixture. The layout dimensions may not be exactly where your purlins are. The closer you can come to the layout dimensions the better the results will be. All fixtures in layout hanging 1.5' from ceiling surface.
The Lithonia fixture I used is basically the same as the Cooper. Cooper doesn't have an 8ft IES file.
Here's the Dialux report (linked)

t-dog - no promises - if you're in a hurry I can't help you. There are only so many hours in a day and I am insanely busy. Your light sucking black flooring looks nice, but isn't going to help you any. How big a fan is your wallet for lower wattage LED fixtures? Are we talking budget friendly James LED strip lights or higher end "aesthetics matters as well as efficiency" type fixtures?
roadrunner255 - assuming purlins are 8", then 6" from the purlins = 1.17ft from ceiling surface. That's only 4" difference from the original 1.5ft from ceiling surface suggestion. I tested it and it only changes the avg at workplane illumination from 86fc to 85fc. You're good to go.
Even though I've had to mostly stop doing lighting layouts, I couldn't resist the unique design INTMD8 came up with.
DAAAAMN Jim! That’s not a garage, it’s a Shrine! Your project is an amazing transformation. And fast - I only posted the layout 2 weeks ago. Looking forward to any comments on how much light reflects off that floor onto the undercarriage when a car is up on the lift.
Pictures are great, but since they're a poor indicator of actual light output what really matters is your visual experience in the space. Is the lighting good for reading a manual or rebuilding a carb? From the picture, it appears the rear of the Ferrari needs the light from the 8ft area.Thank you!!! I will take undercarriage pics as soon as I run something up there![]()

If you did the same layout = 38 Maxlite housings + 76 James LED bulbs = $1463, yields 83fc avg at 30" work plane - so it's close to the 88fc from the fluorescent layout.Platonic Solid,
My structure is up and I am getting ready to do rough wiring. When getting blue board for my radiant floor at the local lumber yard, I saw a shop with LED lights and the brightness and whiteness was amazing. If I were to use the LED Tube you recommended:
18W James LED $11.99 x 20 = $240 + Free Shipping
(Be sure to get frosted lens)
How would that effect the layout? Would I still need the same fixture layout?
Thanks,
Than
Sorry, I'm not available for hire. Some have given "tips" which is appreciated, but never really covers my time.How much do you charge for that?

If you used Qty.21 of the 7000lm Lithonia ZL1N (linked) = $3340, yields 86fc at work plane.

naturalgas - Suggested fixture: Lithonia ZL1N (linked) or similar output. Qty. 24 (assuming 3 garage doors, thus 4 rows of 6 fixtures between garage doors/walls) ($3816) yields 82fc @ work plane in an empty space.
Fredo Starr - You are talking about this Feit shop light (linked) @ $70 for 2, thus $35 ea. = 3700lm / $35 = 106 lm per $1. Not intended for hardwired install. When fixture dies you replace the whole fixture.
Compare to James LED fixture on page 1 of "The Brest Light Fixture ..." thread: 4500lm / $38.50 = 117 lm per $1. For hardwired installation using replaceable LED bypass bulbs.
The better long term option is the James bulbs with Maxlite housing. The initial cost and performance differences are negligible. Either way, you don't need a wrapped fixture for your 8ft ceiling as long as the bulbs are not glass.
