No wonder you can't see anything in there. How big is the space?
You're seeking aesthetically pleasing LED fixtures with good light output, thus budget comes into play. Are you seeking the lowest cost option? (no point in me suggesting a $150 fixture if $50 per fixture is the limit).

The 2 bay is 22' deep and 23' wide. The single bay is 20' deep and 13' wide at the door. The two are open to each other but offset. The opening is 14' so it pretty much flows as one space.
I haven't given budget any consideration. I guess I would be looking for value but off the top of my head I would certainly want to keep it under $1000.

Off the top of my head:
Fluorescent wrap fixtures would run you at least $750.
LED wrap (fluorescent enclosures with retrofit LED bulbs) might be possible at $1,000.

At closer look, I have no recommendation other than increase your budget or give up on LED.
$1350 for LED wrap or $1100 open tube LED.

2000xpsd 31 x 47 x 11' - half w/vaulted ceiling 4/12 pitch 16' peak
Layout originally created for 2000xpsd's thread: Lighting design from RAB
Click first isoplot image for PDF with fixture schedule. I had to mix F32T8 and F54T5HO strip lights due to the vaulted ceiling height. Though the fixture schedule shows Qty.8 F54T5HO 4ft fixtures, it is intended that it be Qty.4 - 8ft (92 inches actually) tandem fixtures, but I don't have any tandem F54T5HO IES strip light files.
All images linked to more info or larger views.
Fixtures: (everything underlined is linked)
Qty. 17
Lithonia TC 2 32 120 1/4 GESB available at HD for $45 ea. (or equivalent)
Plus
Qty. 4
Lithonia TZR 2 54T5HO MVOLT 1/4 GEB10PS
or Cooper Metalux 8TSSF-254-UNV-EBT1 or 8TSNF-254-UNV-EBT1.
HD's $70 price tag for the Lithonia is hard to beat. Might want to open one and see what brand ballast is in there before buying 37 of them. I see HD sells what appears to be the exact same fixture without the "R" designation (I assume that means residential), thus TZ 2 54T5HO MVOLT 1/4 GEB10PS for $100.
Suggested Lamps:
Qty. 68
Sylvania 22026 (5000K)
5000K Fluorescent T8 Fo32/850/Xp/Eco3 available at globalindustrial.com for $2.93 each.
Might want to try a local retailer since these are only sold in cases of 30.
Plus
Qty. 16
Sylvania 20949 F54T5HO 5000K $4.68 ea.
Reference linked spec sheet for accurate estimated lamp life = 40-45,000 hrs.
Might want to find something similar from a local supplier since you only need 16 and these are sold by the 40 bulb case.

Thanks. What LED wrap fixture would you recommend? At least that would give me a starting point.
OP

Empty wrap enclosure (edited to unknown) due to excessive shipping charges.
LED Lamps @ $12.99 ea. (must be purchased in 30 piece qty.s) here:
http://www.shineretrofits.com/james...luminum-housing-internal-driver-100-277v.html
Thus $47.90 per 2 lamp 1 wrap housing fixture = 5280 total lamp lumens, minus ~10% reduction for wrap lens = 4750 total lumens out of fixture.
Note: Even in a wrap style fixture, you'll want to stay with the frosted LED lamp.

Great thread!
Amazing work you've done Platonic Solid!
Hopefully you'll still be around for advice and maybe help with the software after I close on my new place and figure out my layout for my shop.

Excellent; thanks. I assume with a wrap enclosure you would order the clear LEDs and not the frosted?
OP

No, clear will look terrible, even in a wrap (unless you really miss the psychedelic 60's). Stay with frosted lens. The only possible exception is if the wrap has a milky white lens (which the one I linked to doesn't).

I don't know what shineretrofits.com normally charges for shipping, but right now through the end of Oct. they have free shipping. Their product pictures aren't always accurate, so pay attention to the description - not the picture - and/or confirm the housing part number at the manufacturers website. Anyway here's a link with a few strip light housing options:

roadrunner255 - Yes, but how fast you recoup depends what your comparing it to, annual hrs of operation and electric rates in your area.
2 LAMP F32T8 FLUOR = 57w
2 LAMP 4ft LED = 44w
13W savings = 0.013kW
Annual Hrs of operation = 2000
0.013kW x 2000 hrs = 26kWh x 0.1158 = $3.01 savings per year per fixture in Texas
0.013kW x 2000 hrs = 26kWh x 0.2040 = $5.30 savings per year per fixture in Connecticut

Platronic,
I was hoping you had time for just one more. I was researching this thread hoping to come up with something close or similar. I am attaching two drawings. As you can tell I am no artist.
What I have is a 30' X 48' pole barn some 50 years old. I have turned it from a horse barn to my shop.
The big bay is 17'6" X 47' with 12' X 11'6" doors at each end The walls are 10"6 on one side going up to an open loft at 16'6". Walls and ceiling are sheet rock in white. The loft area is just cold storage and other than stealing light it has no light needs. It has my lift at one end and the other I plan on using the space for auto-body and wood projects.
The small bay, 11'3" X 27'6" with 9' ceilings and 9' X 8'garage door, is my motorcycle area with a bike lift. It is painted in a very light grey on sheet rock walls and ceiling. It shouldn't matter but this room has 2 picture windows into the other two bays.
Finally the last bay is my welding area. 11'3" X 19' with the same 9' ceilings and walls but in white on sheet rock with one wall open to the auto- body area.
Please ask me any questions and Thank you for the help.
Redhogz.

Platonic- The tool you posted is awesome. I've got decisions on my 60x40x14- I'll be doing a "bright white" painted metal siding on the ceiling and walls of the shop. A couple questions:
-What should I assume for reflection? 80%?
-I've got 30 4' two lamp T8 fixtures. I plan to do the first 40' of the shop with these T8 fixtures and use LED lamps for these Should be about .
-The rear 20' of the shop is going to be the most used. There will be mill and lathe work here, so ample light is desired.
What are your thoughts on these fixtures? I was thinking of doing 6 of these fixtures in the last 20' of the shop, hung 36" from the ceiling. That would give me 103 FC in that area. Is this too aggressive? This jumps all the way to 118 FC if I use a 90% reflection value.

mtechgunman - You say "bright white painted metal on ceilings and walls". I don't know if you're painting it or purchasing pre-finished, but if you have a sheen option go for flat white ceiling and satin white walls. The flat white will provide diffused reflectance = scattering light in all directions as opposed to gloss finish which yields specular reflectance = mirrors light in one direction.
Suggest using the standard default reflectance is 70 - 50 - 20 (Ceiling - Walls - Floor).
Let's assume you're ceiling and walls start out as 90% reflectance. It won't take long before general use dirt builds up on them making it 80%. A few years down the road it'll be more like 70%. Though your walls may be 70% down the road, you'll likely have stuff up against them at various locations which will quickly knock them down to 50% overall. You could set the top 7ft of the walls at 70% if they'll be mostly bare.
I can't comment on construction quality since I've never had one of the Lithonia IBH12L fixtures in my hands. It is an appropriate lumen output for your 14' ceiling height, but a bit too much from that small apperture to drop them down to 10ft.
The Spacing Criteria (SC) for this fixture is 1.25 (approx.) which means for optimum performance (to get even illumination) math: Mounting height - workplane height x 1.25 (SC) = ideal fixture spacing.
If you exceed this spacing your light distribution quickly becomes uneven.
In your example the math: 10' - 2.5' x 1.25(SC) = 9.375 (fixture spacing). You'd need 8 fixtures at 10ft mounting height to achieve even illumination in your 40 x 20 space. This would be excessively bright even illumination.
Move the fixtures up to 13' and the math: 13' - 2.5' x 1.25 = 13.125 (fixture spacing), now you only need 6 fixtures and your illumination is more even. I actually like the look of 8 fixtures at 13ft best of all.

Ah, ok! Makes sense on the SC. I've learned a ton! Thanks! I'll check into the sheen, but I believe they are a satin finish.

2 wiring diagram options.
Option 1 uses more connectors.
Option 2 uses some wire connection holes from lampholders.
Strip all wires between 3/8" to 1/2".
All wire connections should have slack.
A few extra inches of wire is good.
Coiling lots of extra wire into the fixture is bad = more RFI.

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.

Achieved similar results with:
Same layout as above except eliminate center row and use 4 rows of 4 with HBF 1.16 ballasts. This would cost more and be a special order.
Also similar results with 5 rows of 9 - 4ft 2lamp LED retrofits, thus 45 fixtures 90 James Lamps.
Also played with US Energy Sciences FSL-043208 4 Lamp T8 8 Ft 8' Channel Strip Slimline Light Fixture with Low Profile Reflector, but their IES file for the white reflector is suspect so actual results are inconclusive. Could possibly get away with 4 rows of 4 with this white reflector without HBF ballasts. The specular and Miro4 reflectors are not a good option as they focus the light too much (good for warehouse isles and tall narrow spaces).
T12 is obsolete. Not worth the effort.

shellback,
What are you planning on doing in the garage? Just parking cars and unloading groceries or are you planning on doing precision woodworking?
Same dimensions but ceilings 9.6" doing restoration ...no budgetary restraints. Looking for best quality options. Thanks
Would love to get a lighting layout plan of my garage!
Layout is a little funky, as there was an addition added to the garage (back half).
I also included the locations of the attic stairs and garage door openers. Ceiling height is 8', walls and ceilings are drywall painted white.
Overall dimension of the garage is 21.6' wide x 42.2' deep.
Edit: If it matters,
Front Bay: 21.6' wide, 22.5' deep
Rear Bay: 21.6' wide, 19.5' deep
Thanks!
Kevin

Great info on this site. I am hoping you can help me on my lighting for my new project which is a 30'x30'x12 shop with an attached 30'x70'x10 garage/showroom which has no obstructions in the space. Walls are 6" thick so the resulting space is a foot smaller. White painted drywall ceiling & walls all around.
The shop is used for wrenching on cars and has a lift. Lots of light required here. I've attached a layout.
The garage is used for storing cars. Lighting needs here are not intensive so I hope to use ceiling mounted prism lens enclosed florescents. Currently planning on 2 rows of 10 - 4' fixtures. Either 2 bulb or 4 bulb T8's. Please advise on this config.
Thanks for all you do for us. Steve

Even though I've had to mostly stop doing lighting layouts, I couldn't resist the unique design INTMD8 came up with. He chose the Lithonia ZL1N for the main shop area. Though he has different plans for the 8ft ceiling portion, I stuck some 8ft fluorescents in there to keep the lighting reasonably even. The trusses will act as large louvers to reduce glare from the ZL1N fixtures.
Here's his build thread "36x47 workshop" and below post from the Light Fixture thread:

I have vaulted ceilings in the area I want to use these. 15ft peak and 8ft at the side walls. All white, and white floor. 8ft between the trusses, I was going to surface mount them centered on the ceiling between the trusses, mounted end to end from peak to wall.
Thanks.

DIALUX Isoplot PDF (linked) Note the floor reflectance has been set to 40 rather than the standard 20.
Here's a link to a simple PDF with fixture location dimensions at ceiling pitch.

60 fc under the car at 30" worplane is impressive. The car undercarriage surface has 30fc.
