Light Fixture Layout Collections

[brem]

Hello,

I'm trying to come up with a plan for lighting a new garage -- 26' x 36' with 10' ceiling. I think I will go with the MaxLite / James 4' T8 combo that Platonic Solid recommends as it seems like a good value.

The garage is basically an open rectangle designed for 3 cars. There is a workbench in one corner, but beyond that I'm basically looking for even light.

I initially thought to just put the lights in a grid so there would be 3 rows and 5 columns as in this attached image. That calculates to 78 lumens/ft^2 which seems like quite a lot. I'd like it bright enough to work out there but it doesn't need to be crazy bright -- or should I go brighter?

I see other design patterns where instead of a simple grid like this, the lights are arranged in other ways, more like several squares instead of rows. Does anyone have an idea of arranging the lights differently would help the light be more even? Thanks.

After looking at all the different layouts I created the below. Would you mind making an recommendations or notes?

Each "blue" bar is a set of two 4' t5 lights that will be hung from the purlins.

The building is a 35x42 insulated metal building with 10' walls and a 4/12 pitch roof. I was thinking of using some Home Depot bought t5's. Open to recommendations.

Thank you in advance for any help you can offer.

Are you sure you want/need T5's? Quality, high ballast factor T8's would be my choice with quality 5000k bulbs. They are less expensive too! T5's tend to glare below 15-20 ft.

Metal building, 35 wide, 10 tall. This would equate to roughly 9.5 high inside at walls and 15.5 at peak, inside... Sounds like T8 or T8 LED application.

My $0.03...

These are the fixtures I bought. I will have 24 of them in 2400 sq/ft. Should be in this week, shipping today. I intentionally went with a fixture with a high (1.18) ballast factor. Lumens were more important than energy consumption!

For the 30x60 lean I just chose 12, T8 Tandem strip lights @ $46 and some change.

T8 Highbay http://www.shineretrofits.com/catalog/product/view/id/1540/s/us-energy-sciences-ohb-043204-ea-h-4-lamp-t8-high-bay-full-aluminum-body-light-fixture-with-high-power-ballast-and-miro4-reflector/

Also chose these highbays over some other choices due to surface mount capable.

Enjoy,

Did you order those lights with or without the acrylic lens? I see that Platonic Solid recommends lens for T5s. I wasn't sure if that held true for all "High Bay" fixtures used below 15'.

 

[nsula_country]

I did not order lenses for these. These were T8 fixtures, surface mounting 16-20' They are more of a "mid-bay" fixture. Shipping today or tomorrow. Yay!

T5 is much more "specular" when looked at directly. This is what causes glare. Hence why they recommend mounting them above 20' high. T8's and T8 LED are more diffused due to the larger diameter lamp and less wattage. T5's are bright as hell! Just not a good fit unless a diffuser is used at lower mounting heights. We have them in our plant at about 25-30' and you don't want to look straight up at them.

[MJockey]

Okay, thanks for the info. When playing with DIALux, it looks like I would need 6 bulb T8 fixtures to get close to the foot candles the 4 bulb T5 fixtures with acrylic lens produce.

I need to work the #s to see if it makes since to use led T8 bulbs or not.

 

[_Stang_]

What would you guys recommend for my new construction attached 3 bay garage? Electrical plan below. I was thinking of an 8' four bulb T8 fixture at each of the 6 ceiling boxes (or two 4' two bulb fixtures end to end at each) with LED T8 bulbs? Garage is 30' wide, 26' deep on the large door side and 22' deep on the other side. 10' ceilings. Also attached is the general idea for layout cabinet / workspace wise.

I wanted to follow up on this thread... It took me awhile but I finally finished wiring it all in this past weekend. I used the recommended fixtures and bulbs as well. Walls and ceiling will come later which will make it even brighter but the light is great! Can't wait to start working on the car!

 

[nsula_country]

TTA89,

Looks great! Seems bright. Are you going to have to remove the lights to put up ceiling?

TTA89,

Yes the lights will need to come down but at least all the wiring is where it needs to be. I'm using the lights a raceway so there are only a few spots where the wiring comes in and out.

I was quoted 5K to do drywall without insulation that needs to be added and I have other priorities first... Like a heater so I can work on the car in the winter. Realistically, the ceiling is a few years off if I'm being honest with myself.

 

[nsula_country]

That is fair, completely understand the situation. Lights first! Keep it up the progress.

One thing I wanted to follow up with regarding T5 bulbs.

I needed 58 of them and I found this place http://www.globalindustrial.com/ that sells them 40 to a box for $110 plus shipping (9 bucks to NH). I ordered 1 box so I could make sure they looked good and all that. Here is the actual item I bought:

http://www.globalindustrial.com/p/e...inear/20949-flourescent-t5-fp54-850-ho-eco-t5

The box came and was wrapped well, no issues. I was actually surprised how small the box was with 40 lights. So I placed a second order for another box a few weeks later. The second box was not wrapped like the first and it looked like Sylvania changed the packaging as their box was different. I opened it up and about 10 of them were broken. Luckily I only needed 18 good ones to finish my lights.

I took some pictures and sent an email off to customer service asking if they could send me 10 replacement or just credit me back for the 10 broken ones.





I received a reply today and it sounds like they are going to send me a new box with 40 bulbs AND credit me back for the entire box of broken ones. How awesome is that?! Will I order again? Hell ya

Good Morning Michael:

So Sorry for the Delay, I noticed you said only 10 were damaged in Shipment but I’ll just issue you a replacement for 40 since that is the minimum Qty I can enter, please be aware you will receive an invoice for this replacement but it Will Not be a Bill, we just send invoices with our replacements, I’ll be sure to also issue you a credit for the bulbs you received damaged, so sorry for this Inconvenience,

Have a Wonderful day!

If you don't mind me asking... what exact fixtures did you order and from who? I have 16ft ceilings and have not found a lighting layout that matches my build as close as yours does... at least for my RV bay anyway. I like your layout. Can you also tell me what kind of canned lighting you used in between the strips and did you have them on the same circuit? I imagine it would be nice to have soft lighting for entertaining since my building is more of a man-cave but when I need the 90fc I can just hit the T5 switch!
Thanks

40x40x16 with loft Re: Light Fixture Layout Collections

Thanks for everyone's perspective and experience on this thread. I am close to framing and this thread has given me so much info, my head is spinning. I have 16ft flat white ceilings except plan to use canned lighting with softer colors in my loft and bathroom and bar that have 8ft ceilings. The work areas are for welding/cars/lift etc. My head is spinning with all of the layouts I have read through and I am having a hard time understanding how to lay the lighting out and how many of which type...

I have watched this thread grow from T5 to modifying fixtures for LED to now not having to modify anything and its pretty confusing for the do-it-yourselfer, but damn it, I'm going to learn this stuff!

I am sure I am making this harder than it has to be; my budget is tightening quickly and I am on the hook for all lighting and electrical cash out of pocket so any advice to save money while keeping bright would be appreciated. Canned lighted areas will have soft colors bottoms of walls brown. Open Bay shop areas white walls and ceilings. Loft is a rec-room area for playing.

Short bay will be 2 post lift, long bay for RV and weld shop in the rear walls. All Floors acid stain rust color. I have seen a couple of builds throw in some canned lighting even on high ceilings on a separate circuit to switch to softer lighting when +80fc is not needed. I like this idea for entertaining, clear out the bays and switch the shop areas to softer lighting and open up the bar...

I tried to use the software... I don't have the skills or patience and my laptop did not like running it for some reason so I stopped and deleted all the files. If a pro has some time to help me figure out T5HO vs. LED and best quality/cost/bang for the buck, that would be greatly helpful. My plans are compressed but basically a 40x40 with a bar and bathroom in the rear 12x24 and loft above it all so the high bays are 40x16x16 rv/weld, and 28x16x16 for the hotrod bay with 2post. I plan on separate bays circuit and keeping the loft, entry, bar, bath and under loft canned lighting on the same circuit.

Thanks for any additional advice you can give

Hello Platonic Solid I have been around for a few years looking around getting ideas for my project. I'm currently in the middle of finishing the sanding of my calls and ceiling to get ready for paint. Looking to get some help with lighting. I'm from canada so not sure if that makes a different on type of lighting being used. So I enjoy working on my car and the garage has become the focus of this summers project and long over due as i have been in the house for over 5 years. The garage is 18'4" wide and 19'8" in length. There is 2 O/H garage doors 8'X 7'. There is a door in the right corner of the back wall going into the house and there will be a shelf unit/work bench that will run the width of the back wall and come out about 2 feet in total across and a height of just over 11' to be able to store wheels and other things as tool box and etc. The
ceiling is parted into 2 sections. Front section is about 7 feet in length and has a height of just over 12 feet. The back section of the garage is just about a foot taller then the front. So when you look at it, there is a upside down step. I'm planing on
putting a 4 post lift on the left side bay when looking in from street to use for both car storage and working on car. I currently have the standard
garage one bulb light plus the garage opener on the right bay when looking in from the street. I need some help in making sure i have the right amount
of light that wont leave me in the dark when working on my cars. The walls and ceiling will be painted white but not sure if high gloss or or semi gloss with a small boarder around. I'm going to be placing a sub panel to allow for more outlets as well. Thanks any help will be great.

Hi Revamp,

I used the Lithonia 8 foot fixtures from Home Depot. It should be these fixtures - http://www.homedepot.com/p/Lithonia...ture-TZR-2-54T5HO-MVOLT-1-4-GEB10PS/202516724

For the cans, I just picked up a box of IC rated 6" cans and put LED replacement light bulbs. I think this is the box - http://www.homedepot.com/p/Commerci...rtight-Housing-6-Pack-CAT7ICATA-6PK/202256649

I wired my T5s into 3 switches and I put them onto 3 different circuits. I didn't really need to do that but I had the space in the panel, so why not? That way if I blow a breaker I'm not in the dark. The cans are on two switches on two circuits, the circuits were installed before I bought the place. I turned the "hanging light bulbs" into cans and added a few extra. They work well if you need to run in and grab something or whatever but they are useless if you want to work out there.

 

[PALYDIN11]

Hello. I have a 28 x 32 (2 bay) garage with 10' ceilings. I will have a work bench but mainly work on cars and motorcycles. One vehicle is a Ford Raptor. I will probably go with drywall painted white. Do you have a lighting setup that will work for me? Thanks.

 

[owdlvr]

Currently working on my plans for the new shop, I don't get possession until mid-August, and won't move in until October, but I do need to plan and budget on finishing the shop. It's currently a bare shell. Inside ceiling is sloped, 2x4's on 16" centres. I'll be insulating between the rafters and covering with paneling (likely OSB). For lighting, I've found a scrap dealer who's just pulled 4ft and 8ft T8 housings out of an office building and warehouse. At $10/unit, I'm probably going to go ahead with these to try and keep my initial build costs down.

Garage dimensions (inside dimensions):

Inside Dimensions (and potentially approximate)

Interior Ceiling Heights:

My initial guess on how I'll setup the shop:

The lighting probably looks really odd...but I've sort of based it on my current shop, which has low (8ft) ceilings, setup with three 4ft fluorescent T8 lamps above each car. With the air-cooled Volkswagens (engine is in the back), the best upgrade I did was to place one of those lights right above the entrance door. With the garage closed, I have light that shines right inside the engine bay. With the door open, the lights are blocked but natural light takes over.

For this new shop setup, I've done the diagram with two 4ft lights in each position, as I occasionally wish I had a little more light. My thought is to setup the lighting so half is on one switch, and the other half is on a second switch. Bay one (on the left) is setup so that I have future lighting over where I think I’ll put my lathe and also more light for painting / finishing.

Thoughts on how I should tweak and or change this?

 

[Utahcarguy]

Hi there. I could use some help with my garage. You'll see the lift and workbench area, which will have higher ceiling clearance and the rest of the space will be 10' ceilings.

The cool part about this garage (besides the size!), is that the three cars parked next to each other will be the "fun" cars and can been seen through the one-way glass in my speakeasy lounge!

I'd like some lighting and layout suggestions for the garage as well as a cool way to illuminate the 3 cars on their own. Thoughts?View media item 62036View media item 62037

Thanks, I think. What kind of details would you like? The lift will be on the far side of the garage and storage above the rest of the garage. This is our first home build, so feedback is helpful!

 

[cobratom]

Platonic Solid,
Wow. First and foremost. Great Resource! I thought I was just going to go based on an electricians suggestions until I saw this thread. Completely has me rethinking my approach/plan.

I assume T5HO are what the current recommendation is for a high ceiling, can you suggest how to distribute them?

My total shop is 50 deep by 60 wide however a mezzanine with a office will be built on the North West side of the building leaving a space of 48 wide x 50 deep. Interior height is 17'6" to the trusses.

Thank you very much!

 

[nsula_country]

cobratom,

First, is this stick built?

High bays are recommended with that height. I am currently wiring and hanging high bay T8 fixtures in my 40x60 of comparable height.

I'm installing 4 rows (40' wall) of 6 (60' wall) suspended on 18" of jack chain. Still working on 1st bay, but they are bright. 5000k bulbs. Should end up with about 80 FC at work height (2.5') without shadows.

When I update my build, I'll include lighting info and maybe a spacing layout.

Using this spacing you would need 5 rows of 6, if using High Bay Fluorescent/LED.

Good luck,

CT

 

[cobratom]

Yes. Stick build. Every height I have seen Platonic Solid recommend above 15' seems to feature t5HO

 

[nsula_country]

T5HO and T8 High Ballest Factor 1.15+ are used above 15'. These fixtures have 4-8 lamps, some 30'-40' high.

Research T5 vs T8 before you purchase 30 fixtures (using my spacing). The pros and cons of each are interesting. Both are valid options. One cost less, uses less energy and produces almost as much light.

Re: 40x40x16 with loft Re: Light Fixture Layout Collections

Any chance I can get some PRO help on this layout? My electrical guy recommended the Lithonia 2ftx2ft High Bay LED's that Home Depot sells http://www.homedepot.com/p/Lithonia-Lighting-2-ft-White-LED-High-Bay-Light-IBH-11L-MV/203812710 for $159 each. I don't understand how I would lay these out to reduce shadows and space them out enough to make them economical and not buy too many due to the price.

For the loft area (8ft ceiling), and ceiling under the loft (8ft ceiling), I am thinking of using these luminaires http://www.homedepot.com/p/Halo-5-i...ight-with-80-CRI-3000K-SLD606830WHR/204732243 Reason is they mount right into J-boxes with no fixtures. I have them laid out every 4 feet in the loft, under the loft, in the kitchen/bar, one in the bathroom.

I really appreciate your opinions on the right type of lighting between the High Bay LED's, T8, and T5HO

I did just figure out that the Home Depot IBH-11L is way less efficient than the IBH-12L that Bee's lighting has for just $30 more, and still cheaper than HD's regular price. http://www.beeslighting.com/product-p/ibh-12l-mvolt.htm

I am wondering if I hung these down at 15 feet and put one on each side of the RV bay, one in the back where the welding are is at the back of the RV bay, and one in the front of the lift bay near where the loft begins/front of the kitchen/bar, that would give light everywhere except the right side of the lift bay along the loft. The ceiling under the loft will have canned lighting anyway so I think I can get all the light necessary with 4 of the IBH-12L's from Bees...

But... what do I know.

Compare the HD spec sheet showing 85 lum per watt vs. the Lithonia model IBH-12 110 lum per watt and the diva light models 115 lum per watt. The Diva Light seems to be the biggest bang for my $$$.

I will add that I have not been able to find any discussions on High Bay LED lighting in the threads for 16ft ceilings. Great amount of information below 14ft though.

Let me know if you find any good information. I was going to use strip lighting and James bulbs, but no data on mounting them at 16foot and everything else I find talks about T5HO being too bright.

 

[kkosh]

I would love help on laying out lighting for this. I will have 3 car lifts installed and 12 foot ceilings. No windows in the garage. Should I do LED? thanks so much.

 

[texcattleman]

First post EVER, so go easy

Hello Platonic Solid,

We are breaking ground on a 36 x 60 workshop/ranch shop next week. Im struggling with the lighting plan (effectiveness of the lighting around the 3- 12x12 roll up doors, and so on...

It's pretty much wide open inside except for the long wall with only windows (3 30x30), that is reserved for work benches/tool chest, welding table, etc...

The end gables will have 1-12x12 roll up, and 1- 30x70 man door each. with 2 30x30 windows. The opposite long wall will have 1-12x12 roll up (centered) and 1 man door (30x70), and 2-30 x 30 windows as well. Outside lighting is preferred to be large commercial type dusk till dawn security lights, with farm style porch lights near man doors. There will be a gutter system in place as well as a 2ft. soffit on the long sides, and a 1ft. soffit on the gabled ends.

I added 4 screenshots

 

[GunRunner]

Platonic Solid,

First off, I think this is a great thing that you are doing for the members here and probably can't be thanked enough. I am in the process of my 30X40 build which will have flat ceilings with an apartment upstairs. The will ceiling height will be right at 11' but not less and more likely 11' 2" in the rear and 11' 7" at the door measuring from the floor. I'm still in the air about what fixtures I want to go with but I'm pretty sure I want to go LED and probably 5000K color. Would you be willing to look at my plans and help me with a lighting layout and a recommendation on a good fixture to use? I saw you did a layout for fdkss and was wondering if his layout would be something that I could use since his is 30X40 with 12' walls. Thanks again for all you time and help.

Also, the garage door is 18X9 and I plan on using a jackshaft style opener so it leaves the ceiling open as much. In the single photo labeled 8504-4, I put on there where I anticipate the 2 post lift to go but that won't go in right away. I also marked where I anticipate the workbench to go but I'm also toying with the idea of it going on the back wall in front of the lift.

 

[jonwrong]

I think I have seen enough posts about suggest light layouts to know about what I should do. Can anyone weigh in on flush mounting lights on a ceiling with a 2.5 inch per foot slope? I think the chains are ugly and would prefer to just flush mount.

My ceiling is vaulted from rear to front, so I would be mounting the lights in line with the slop along the perimeter of a lift in the middle.

 

[nsula_country]

jonwrong.

My ceiling is 3/12 pitch. I was going to surface mount, but instead bought a roll of jack chain. Lights are on 6" or 18" chains depending on where they are in the shop. When you use chains then you have to add in a junction box, cord grips, so cord, ect... for a hardwire application.

[evoluzione]

Platonic Solid; thanks for this great thread. Just read through most of it. Great contribution to this forum!

I am at a point where I have finalized my garage layout. It's a bit quirky, but it's what I have so it will have to do!

Any tips?

thank you!

Edit: Forgot to mention height; 12ft roughly

 

[TooMuchHair]

Does anybody know where Platonic Solid is? I haven't seen anything from him in quite awhile.

 

[SiGmA_X]

Do we have another expert who weighs in now that Platonic Solid has gone AWOL? I could use some input on layout for LED's in a standard 21x21ft 2 car with 13ft ceilings and some glulam beams that hang down 8-12".

Would hanging the lamps under the beams be a wise idea so they're all at the same level, plus closer to the work surfaces? Potentially 3 rows lengthwise ~2ft out from the outside walls (so the leftside benches are well lit - right is 2ft of storage so less important) and in the center of the garage, with another light or two perpendicular over the workbench at the front of the garage?

 

[Wileel]

After reading all of the outstanding info on this thread, I'm looking for a little help. I would like to play around with the visual 3d tools but there is an over whelming amount of lights to choose from. Does anyone know the best match for the Max light fixtures and matching 5k bulbs listed in the "best lights thread"

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 linked to this bulb on a prior layout at $3.80 ea. from 1000bulbs dot com, but that may have been an error on their part as they now don't carry it at all.

Well, I finally got power turned on today. All I can say is wow. I couldn't be happier with the results of your recommendation for lighting. It is exactly what I hoped for. Now shadows. Even light everywhere. No glare. Words can't describe how happy I am right now.

The only change I made was where the office will go. Not sure when I'll get that done, so I put two fixtures where you said to put the singles. Which is what I figured you'd say to do if the office wasn't there.

Each bay is on it's own switch, so I don't have to run everything all the time.

I ended up getting the bulbs from Global Industrial for $2.75 a pop.

Does anybody know where Platonic Solid is? I haven't seen anything from him in quite awhile.

Well, ****. I didn't even look at the end of this thread before posting my last.

I hope he drops back in, the man is a wealth of knowledge. It's been over a year since he did the recommendation for me.

Hopefully my finished pic will help show the end results of what his recommendation was for a shop of 80'x50'
