Light Fixture Layout Collections

[Platonic Solid]

Don't know about cell phone, but FM radio could be an issue. Fixture in #33 uses residential ballast. It's not a tandem and I have no idea if/where you can find a tandem version.

I called Cooper lighting and they suggested this as the residential version of the same fixture

Thanks for the info provided thus far Platonic. Would it be worth checking out my garage? It's a small space with some fixed shelving that makes the space feel even smaller. I'd like to optimize light around the vehicle space and provide plenty of light to the work area on the left. Is the attached graphic I made enough information? I do have task lighting installed under the cabinets over the workbench.

I already bought a bunch of Lithonia 205CKL 4' x 4 bulb fixtures but have not yet installed them.

Thanks,

Steve

Sounds reasonable, though I prefer the higher efficiency of the wider SSF housinig for T8 lamps. This post shows the difference in output between the SNF and SSF.

baneonrt, I have several layouts in cue. I would do something along the lines of the layouts in posts: #10, 11, 14, 15, 33 & 34, using either F32T8 bare 2 lamp strip lights or 2 lamp wrap version of the fixtures you purchased. How many 4 lamp wraps did you buy?

I purchased 8 quite some time ago. I saw this thread and thought the purpose was to provide custom lighting distribution based on specific garage layouts. I figured the cabinets on the walls of my garage would have a bigger impact so posted my setup. You're not charging for this service so if you think one of the previously posted layouts is fine then that's fine with me.

Plus it was an excuse to play with sketchup some more

I recently purchased a new home with a 21'5" w x 25' d x 10'3" h garage. I do all my own maintenance, auto detailing, and wood working. Light is very important to me, so rather than play the guessing game myself I thought I would ask for yalls help. Here is what I was thinking but I am completely open to changing it!
View media item 52063 I am open to any fixture type however usuable lumen output and energy efficiency are paramount.

Platonic,
For those with standard rectangular shape garages, is there any generic T8 strip spacings based on different ceiling heights? I assume that the spacing of lights on an 8' ceiling would differ from that of a 10'? It appears 11.5' spacing is typical on your designs in this thread for 8' ceilings. What would you recommend for a 10' ceiling? I know you have a lot of layouts in queue and I don't expect you to do a design on mine, but below is my dimensions and lighting layout. Based on this thread I will add 4' strips on the ends to form rectangles, but am wondering if my 6' spacings are too close?

No hard and fast rules for garages. You can get by without the fixtures on the ends that you mentioned if you run them full length as shown in isoplot below. I used 12 8ft Tandem Lithonia TC232 for this plot ($56 @ HD). If possible, which it appears to be in your case, you want the fixtures between the cars and between the car and exterior walls.

 

[Platonic Solid]

Falcon67, do you have a question?

 

[Doc986]

Need help with my residential garage. We're at the stage in the build where the electrician and builder are requesting my preferences for garage lighting. I don't anticipate doing anything but the most basic work - oil changes, tire rotations, etc. So, I don't need shop-quality light coverage but I do like nice, even lighting.

Thanks in advance!

Are those Lithonia TC232 narrow or standard width? I looked both at Menards and Lowes and they only have narrow 8' tandems, so this would be golden if HD has the standard with 8' tandems!

Also, how are the ballast in these?

 

[Platonic Solid]

Though Lithonia's C Series General-Purpose Strip spec sheet doesn't detail lamp spacing, it does confirm standard (not-narrow) 4.375" housing width. Sorry, no idea on what ballast is in there. You'll have to pop open a box to find out.

 

[buening]

I found another TC232 from Home Depot that is cheaper than the one you linked to. You know more about this stuff than I, can you tell what the difference is between the TC 232 120 1/4 GESB and the TC232 MV?

Only difference is the fixed 120V vs 120 thru 277V variable supply voltage ballast.

Hi

trying to figure out best/cheapest layour for the 40x40 second phase. This is a block garage with 2 20x40 bays seperated by an 8ft wall. The side wall height is 14'8" with a 4:12 pitch to a 21 ft peak. I have the opportunity to by some 400 watt high-bay lights for $65 or I can do florescent layouts, maybe buying half at a time and running all of the wire. what are your thoughts on florescent or high bay.

 

[rsnip988]

Thanks for all of the great info and awesome schematics! This thread has answered most of my lighting questions without me even having to ask any!

This is a great thread. I've read through a lot of it, but I don't think I've seen a setup that matches my garage. I'd welcome suggestions for lighting in mine. It is a 2 car tandem, although I actually can squeeze in 3 cars. Anyway, it currently has two 4' 2bulb wrap fixtures with 4100k bulbs.

I use the garage for auto maintenance and detailing. Whenever I'm detailing, I found myself using a freestanding light in order to have sufficient light on the sides of the vehicle. Oh, and I typically park the vehicle in which the work is being performed in the center of the garage, usually under the one 4' fixture.

I'm open to T8 and T5HO, but I'm pretty sure T8 with 5000k bulbs are gonna be the ticket. I'm not sure of placement, size, or number of units, though. The circuit is a 15A.

Finally, I have a cabinet and rolling toolbox that takes up half of the room on the left wall between the two doors. I don't have a workbench, so I'm really just looking for ideas to generally light the garage while giving me ample light for detailing.

Here is the layout with dimensions. I've marked the two fixtures as well as the placement of the garage door opener.

Any help is greatly appreciated!!

Thank you!!

 

[Platonic Solid]

CaveRacing, you left out a critical detail . . . ceiling height (and is it flat).

Indeed I did! The ceiling height is 10' and yes, it is flat.

Thank you!

I’ve decided to stop doing lighting layouts. It takes too much of my time and I have too many other projects I want/need to do. I have a few layouts that I’ve done for members that still need to be posted. Anyone that I’ve promised layouts to will still get them. When the rest are posted, there should be enough variety here to satisfy the majority.

For the “how many fixtures do I need” question: You can use Visual-3d and set the 30” workplane to 90fc.

To take it to the next level and make layouts as seen in this thread, install and learn Dialux evo. It’s serious software and it’s free.

If you experience issues with Dialux evo 5.0, try DIALux 4.12.0.1. It’s less prone to crashing and does much faster calculations. I built a respectably fast PC and some evo layouts take 15 minutes to calculate. I expect some of the Dialux evo issues will be resolved when they release version 5.1.

I was wondering when this would happen. It's so time consuming. You've been more than generous in doing this for people. The layouts that you've done so far are sufficient for a large percentage of garage designs. People can just adapt these layouts to their dimensions and they'll be fine.
Good job.

I just want to say thank you. I have been planning lighting for my 22x23x9 2 car garage. I am going to use your recommendations for the 28x24x8 setup.

Again thank you so much!

Can I get some help? Every time I look into lighting I feel like I'm further away from knowing what to do.

Shop specs-
40'x60'x14' walls. Flat ceiling. Walls will be OSB, not painted. Used for auto work, gunsmithing and metal fabrication.

 

[Platonic Solid]

Fixture and bulb cost = $1/sq ft painted, $1.60/sq ft unpainted OSB
= $2,400 painted, $3,840 unpainted OSB.

Is ceiling unpainted OSB too?

 

[mtechgunman]

Haven't planned that far yet, open to options.

 

[Platonic Solid]

Too many variables. You'll have to make some decisions and a floor plan before I can help you. For the preliminary stage your at, the layouts in this thread should suffice.

 

[djre4orm]

Platonic, thanks for posting the software! After a pretty steep learning curve, I am working on my layout. Any pointers welcome

Re: gtae07 Suggested Fixture Layout 28' x 24' x 8'

Alternate Lighting Layout suggestion:

​

Fixture Recommendation:

Lithonia SB232 $32.97 on Amazon.

Wraps (lensed fixtures) are recommended for 8ft ceiling height.
At that price the ballast is probably a budget model that will die within a few years, but by then you'll have a choice of upgrading to a higher quality fluorescent ballast or installing ballast bypass LED retrofits.

Light fixtures on low ceilings make longer shadows, thus placement becomes more critical.
Lumen output can be controlled via lamp selection:
The Sylvania OCTRON 800 XP XL ECOLOGIC3 Lamp spec sheet is a good example of the different lumen outputs available.

I am wondering why you recommend wraps for the 8ft ceiling height...Was gonna go with 6 8ft 4 tube open fixtures in my 24 x 24 with 8 ft ceiling now you got me re thinking it....

thanks in advance

Dan

 

[Platonic Solid]

Wistrick - Exposed lamps at 8ft or less are more prone to breakage.

 

[buening]

Platonic, do you have any information on the ballasts used on the Lithonia lamps at Home Depot, specifically the 518-902 standard vs 247-790 High Output?

http://www.homedepot.com/p/Lithonia...rip-Light-TUNS-2-32-MVOLT-1-4-GEBHL/202193181

http://www.homedepot.com/p/Lithonia...TC-2-32-120-1-4-GESB/100192753?keyword=518902

I assume the difference is only in the ballast and has a higher ballast factor, but can't seem to find any specs on how much of a difference there is between the two. I believe they used Accupro ballast in the past, but I could be wrong

 

[Platonic Solid]

buening - you'll have to open them and look at the ballast. The ballast spec P/N of the fixtures sold at HD don't match Lithonia's spec sheets. There's nothing there indicating either fixture is "High Output" (assumed to mean High Ballast Factor).
The 120V spec of the TC fixture could be a residential ballast - thus FCC Class B EMI and RFI rated = less potential interference with TV and radio than commercial universal voltage electronic Class A.
Here are the spec sheets:
TC 2 32 120 1/4 GESB
TUNS 2 32 MVOLT 1/4 GEBHL

You have to understand that almost every single Home Depot product listing is completely incorrect. It's like they dont understand lighting at all and are too lazy to try to figure it out and put the correct info out there for people to use. I guess it comes from the fact that they dont think that their customers will understand it anyway, so they just dumb it down as far as possible.
With the limited, and incorrect, info they provide and from looking at the Lithonia site, it appears that this fixture has a "high lumen" (not HO) ballast, but you should open it and look to be sure.
A "HL" ballast typically has a ballast factor of 1.18 -ish. You can approximate how many lumens will come out of a lamp by multiplying it's rated lumens by 1.18. This still wont factor in how many of those lumens will come out of the fixture, as some of them get lost up in there.
All those extra lumens come at some expense. This fixture does NOT consume 128 watts as the Home Depot site insinuates. It uses 148 watts due to the higher BF.
Never take the specs on the HD site seriously.

[buening]

Thanks guys! I was just trying to weigh whether I get the cheaper one and replace ballasts with better ones or just get the "HO" version to save me some trouble, but wasn't sure if the "HO" version was worth a ****. I'll pop one open next time I'm there and see what it says. Thanks for the info

24x24, 10' flat ceiling.

Planning to use 4 rows of (3) 4' 4 bulb t8 troffer lights to keep a flat ceiling with my 16x9 being tucked up as high as possible. 2 ceiling fans will also be hung down. Lights spaced out evenly and cupboards will also have light strips under them.

What's your thoughts?

PhantomEB, with that limited info, I'd say all's good except switch from 4 lamp to 3 lamp fixtures.

Thanks. I have 2 of the 12 as they were given to me free, never installed. Will see if my local shop has the 3 lamp. Sorry I couldn't give pics as it's not being built til tomorrow.

Now I getting close to making the lighting stage.... Why the 3 over the 4?

One fixture is bent so doesn't look right so doubt I leave the other 4 bulb up there if the other 11 are 3s....

 

[Platonic Solid]

PhantomEB 24x24x10:

12 recessed 4-lamp troffers = 147 Fc at workplane
12 recessed 3-lamp troffers = 112 Fc at workplane
12 recessed 2-lamp troffers = 76 Fc at workplane
