Critique my lighting design - Fluorescent T8

So this is my first official post (I did introduce my self, but that doesn’t count…)
My new shop is 24 x 48 with a 14’ eve height and its time for lights!
I spent a lot of time here reading threads and got thoroughly confused, so I struck out on my own with a bit of info from here and made a selection…
I have access to a great price on Lithonia fixtures so using there online “Visual Interior Tool “ I chose Qty (8) "IBZ 632 WD" Hi Bay T8 fluorescent fixtures (I haven't selected a lamp yet but likely something in the 5000K range, that could be another post all on its own…)
So tell me how I did and if I'll be happy with the light in my new shop?

Questions? Just ask, this is all new to me so I may not have given enough info for you to help me

I am attaching a pic of the space, I have (6) 3x12 skylights and a painted floor, Sandstone Armour Seal HS1000

I attached the PDF of the program output but here is the data from it:

I am looking for lighting solutions as well - I just raised the ceiling to better accommodate my lift...

In for pics of your results

Here are my thoughts- with no engineering, just some real-world experience. I'm green enough to favor higher efficiency lighting over incandescent. The main choices are long-tube fluorescent, compact fluorescent and HID. For garage applications, I don't think LED lighting is practical yet. The efficiency of all three are similar, so the choice is based on color and beam pattern. If you favor warmer colors, fluorescents are better. They can get much closer to the warm 2900K look of incandescants. If beamspread is more important, CFL's and HID's are better. Their pattern is mostly controlled by the fixture (luminaire if you want to get technical), so you can have more directional light than 4 or 8' fluorescent tubes. My semi-aging eyes need some shadows to provide contrast.
In the HID universe, MH.s (metal hydride) give the best compromise on color. Sodiums and Mercury vapors are very monochrome- sodiums in the orange range and mercury vapors in the blue. I find these VERY annoying. The 4000K MetalHydrides are a bit on the bluish side, but a good compromise. I have several I've put in normal 8" reflector clip-lights that work very well. Loads of light, fairly directional, and a fairly wide spectrum for good color rendition.
So, it's up to you. What do you like? A wash of featureless light or light directed to where you need it? Highest possible efficiency or good color rendition?
There are always tradeoffs. Check it out and make the best choice for yourself.

I think you will be very happy.

I have 8 of those exact fixtures in my 36' x 64' barn and am very happy with them.
I also have a 14' bottom of truss same as you.

I have them on one 20 amp circuit (i think they pull around 14.5 amps, if I remember right)

I have the 5000K bulbs which i also like, except for the price they are a bit pricey

Thanks for the replies
They are on order should have them soon, and will post pics
They have 2 ballast (3 lamps per ballast) had considered wiring them on 2 circuits, half of each fixture on a circuit
The skylights are great (i keep thinking I left the "lights" on and there aren't any yet!) but I'm thinking on a cloudy day half the light might be a good thing, but not sure its worth the trouble. Its a lot of light and a fair amount of power
I priced LED highbays, and almost did it.... But they were just crazy expensive, couldnt pull the trigger

In my 30x60 I have 8 t-8 fixtures that each burn 1 amp. 8 amps in my cheap power area costs about 10 cents per hour. It's not much.

Don't go looking for metal hydride, I'm pretty sure they're called metal halide.

Well I got everything wired up this weekend!

IBZ 632 WD Hi Bay

Philips 281634 - F32T8/TL750/ALTO - 32 Watt - T8 - 36,000 Hours - 2,700 Lumens - 5000K

Won't know till I start working but I think it's plenty of light and good light, time will tell...

what beautiful tall ceilings

I like your mule! I always wanted one. Not sure what I'd do with it, but they are cool.

Tall ceilings were a function of my truck 1971 AM General M818 and the 12' tall door I needed to drive it in, hence the 14' height
The mule is great! Lots of fun and the cool factor is huge
