I'll save the pros the time of asking their first question: How do you plan to use the garage? Usable light levels for parking and storage are completely different than for other uses.

Multipurpose really.
I will mainly work on my project car in the garage on one side, the other side will be for wood working, some very light (very light meaning probably hardly ever) welding as needed.

Please don't take my advice as gospel, because I'm not a pro, but I think 4 lights will not be enough, unless you plan to add a lot of task lighting wherever you will be working. Otherwise there will be uneven light levels and shadows.
The lighting layout collections sticky might be helpful.
Cory
Ill add more! just want to do it once and be done, figured id ask the pros!
I have a 24x24 garage and I'm planning to put 9 fixtures with 18 bulbs and should have 68 lumens per sq ft should be plenty for me

Forgive me but I'm not the brightest. Read some of these posts on this thread and I'm confused. If I bought these lights (fixture and lamps) from Bees, do they need some kind of alteration or can they just be installed and done. Thanks.

UpNorthEric - Just install and done. The linked housing is prewired for the linked lamps.

Would the diva lights in the first post be appropriate for a 12' ceiling or should I be looking for something else?

ShadowRuleZ - 12 ft is a tough height. Too low for high bay, too high for standard output. I don't know how big your space is, but I'll use 24 x 40 as an example.
24 x 40 x 12 would take Qty.36 2-lamp 4400 Lumen total fixture output strip lights to achieve 87 Lm @ 30" workplane. You would certainly have no shadows, but that's a lot of fixtures to install. Cost $32 x 36 = $1,152 plus installation.
Qty.15 of the Diva Light 8500 Lumen low bay fixtures (linked) or similar output fixture yields 95 Lm @ 30" workplane. No shadow issues. Cost $100 x 15 = $1500 plus installation.
I'm only picking the Diva Light brand based on best deal on Bees website.

in spring of '16 i installed 44 of the highest output James/Diva tubes.
i haven't come back here since until today and noticed that the first page has been updated with a bulb that is the same specs except it's not dual mode (which is fine since i have strips w/o ballasts) but i noticed the beam angle is now 230* vs. the 120* that i have.
i am running these in dual tube strips and went overboard with placement and i know that has a lot to do with this...but, i am curious if anyone in here has been thrilled with the 230* beam models over the 120*?

Dur - I went and bought a large quantity of the the two items listed on the first post here and they just arrived.
In the boxes I see got metal frames with some clips, and some LED flourescent light bulbs. Dont LEDs take ballasts like regular flourescents? I dont see those in here

no ballasts needed. just wires in the fixtures that connect to your power source and on the other end, the bulb tombstones. that's it. easy.
That's basically it. Of course following proper practices to assure it's up to code and all that.
Consider splitting into two banks of lights and using 2 switches. Or 3.
Green wire goes to ground. That would be the bare copper wire in your romex.

These Diva lights work for a 13' ceiling? Shop is 36' x 30' x 13'
Final question - The garage ceiling is built from trusses with a mixture of 16 and 24 centers.
What is the best method to flush mount these units to the drywall ceiling? Would prefer to not be framing out 2x4 and junction box mounts for each - that'll take me months of weekends to get it done, can you buy two mounts similar to what you would do with a electrical box that flip out and press fit against the drywall? These units without ballasts don't seem too heavy to me

You're thinking way too hard. Not too heavy is an understatement - I'd guess about 3 lbs.. The fixture enclosure is nothing but a metal box with a couple wires it. Use a stud finder to locate studs - mark with pencil - hold open housing where you want it - screw to studs from anywhere in the housing (you don't have to use the holes provided). 2 screws should do it (1 each stud). The sheetmetal housing is likely thin enough to use sheetrock screws without drilling a hole, or you could use self drilling TEK screws. Just don't over-torque.

oldno3fan - It depends what you're doing in there. Since 6 fixtures = 24ft that's a bit tight for a 25ft garage.
3 rows of 5 fixtures mounted 9ft high = 85fc @ 30" workplane
2 rows of 5 fixtures (2ft from each wall) = 54fc ...

Wow, what a thread. After three nights of reading I’ve finally made it all the way through the thread. First off, thanks to all, particularly Platonic Solid who have contributed their time, knowledge and expertise to illuminating this subject. (Sorry, couldn’t resist.) It was interesting to see the transition from the start of the thread until now in reference LED’s versus the other options. At this point it seems that the time for LED has finally come, especially for new construction which is my situation.
That said, I’m currently in the process of looking for lighting for a 30’ x 46’ wood shop that I am currently having built. A small office, bathroom and dust collection room will consume up about 8’ on one end with a loft above them. So, the effective space that I’m really concerned about lighting will be 30’ x 38 or 1140 square feet. The walls will be 12’ high with a peak of about 19.5’. The slab has been poured and framing started today in between the gushing downpours of rain we had. Currently, my builder has allowed for 16 fixtures in four rows of four. He has suggested holding down costs by using the cheap porcelain fixture which takes a screw in bulb and then using LED flood lights. Based upon my research thus far I haven't found any floods that would provide enough lumens.
I’ve read, and re-read the updated version of the first post and, because some of this is still beyond my own understanding I’m looking for suggestions. I’d like the shop to be well lit.
So, thus far, I’ve come to the following conclusions:
Get as close as I can afford to 100 lumens per square foot.
Frosted lamps seems to be a wise decision as far as glare is concerned.
LED seems to be more cost efficient all things considered, including the cost of electricity itself.
CRI of about 85.
Does anyone have any suggestions?

what would numbers be with two rows of 6 and one row in middle with 5
I have downloaded DIALux evo, and have been trying to set up my building in it, but there's obviously a learning curve (!).
So, until I get it figured out, here's my question: would it be OK to go with the DIVA strips in the first post of this thread throughout, or would it be better to use them in the outer sloped sections and use something like their LED high bays (http://www.beeslighting.com/product-p/dv-hb13lmv50k.htm) for the 16' section? There will be white painted ceilings and walls throughout. This will be a woodworking and metalworking shop. I currently use a lot of task lighting and would like to not have to do that nearly as often in the new shop.
(It looks like the images have been resized. The dimensions across the top of the drawing are 13', 24', 13'. The side is 44'.)
(Left to right the dimensions read, 9', 13'4", and 16'.)
Thank you for any suggestions!

Assuming Center row is mounted around 12ft at peak and side rows are at 9ft (2ft from walls):
6-5-6 = 91fc
5-6-5 = 86fc
6-6-6 = 97fc
The other fixture you linked to has the same lumen output so you can expect the same results.
thanks bud i truely appreciate it

OneOfEm - You could use the 4400 lumen LED strip lights throughout, but it would take alot of them: 8 rows of 8 (64, 2-lamp strips) = 88fc @ 30" workplane.
2 rows of 8, 2-lamp strip lights in each lean-to section
3 rows of 4 of the 13700 lumen Diva Lite (linked) or similar in the 16ft section
yield = 103 lm @ 30" workplane

I really appreciate the feedback Platonic. I was looking at the layout you did for Paladin306 in the other thread (30'x46') and I've got a smaller space at 24'x46' (2x6 framed so interior is more like 23'x45') which is close to your 24x40 example above. If you used the higher output 13700 lights you suggested to Paladin306, could you get away with a 2 row / 5 column instead of a 3 row / 5 column like I think you're suggesting in the quote above with the 8500 lights? Just like everyone else, trying to save a few bucks if it makes sense.

Wow!!!
Platonic Solid you've went and done it again. Thank you very much. Looks like the who Beeslighting website is down tonight but it's probably just a glitch and will hopefully get fixed this weekend. If you ever come down to Oklahoma please look me up for the steak*** of your choice.I hate to show my ignorance but, can you refer me to something that explains the 100 / 90 / numbers? Is that a reference to the lumens at that particular spot? (The rest of it is exquisitely explanatory and, again I greatly appreciate it.)

Apparently Beeslighting updated their site so now I'll have to go back and update all the links. I did fix the link in your layout post.
Exactly right. Here is a link to a good explanation of footcandle: Illuminance Explained
Here's one of many charts that come up when you google "recommended interior fc levels": This one happens to be from Hubbell lighting (linked), but they're pretty much all the same as the info comes from the IES.

The Diva Lite retrofit tube appears to have gone up in price from prior $8.49 to now $9.88 ea.

I'm already pushing the limits by putting 13,700 lumens at 14ft on Paladin306's layout. Do you have a flat ceiling or is it open to the roof pitch? If open, what is the pitch and will trusses interfere with higher fixture mounting? Posting a picture of the space always makes this more interesting.

Since Beeslighting increased the Diva Lite lamp from $8.49 ea. to $9.88 ea. I could use some help from the group in researching best value.
Here are some for consideration:
18W James tube(linked) 2250 Lm @ $8.54 ea. (must buy case of 30) = $256.20 (shipping cost unknown)
Spec sheet (linked) shows 2 options: plastic 320° beam angle (better for low ceilings and wrapped fixtures) and Aluminum 120° beam angle (better for higher ceilings). No part number distinction between the 2 options.
22W LumeGen tube (linked) 2640 Lm @ $6.99 ea., no qty. limitation, currently free shipping on orders over $25.

Are there any 8' fixtures for 4 LED bulbs? Like this but 8' and reasonably priced.
