Hi all, I am in the early stages of planning my new garage. If all goes well, I'll get what you see below.
Here's the thing, I know nothing about lighting layouts, the talk of Lumens confuses my mechanical brain to no end. I need help finding out if what I have planned is overkill (no such thing right?) or if I am on the right track.

Garage will be attached to house and used for normal vehicle maintenance, small RC hobby work and man cave beer drinkin gathering point. It will be roughly 36'x35'.

The picture is busy I know but you can see what I have planned for lights, storage, work areas etc, looking to use (32) 4' Florescent, 2 bulb fixtures. Let me know what you think.

Thanks a bunch.

No upper cabinets over those work benches ? If so you might want to adjust your layout and or add some under cabinet lights

Also the row of lights in your No. 2 car bay directly over the vehicle won't be of too much use inside the vehicle or under the hood. you might want to think about switching them independently or eliminating them all together

And ya - it looks like you got a LOT of light for the Sq. Footage

Work areas like the over the work benches 80-100 candles, but the car bays could/should be 60/75 candles and switched 50/50 independently for each bay

You can always use task lighting when under the hood or car itself

Hi all, I am in the early stages of planning my new garage. If all goes well, I'll get what you see below.
Here's the thing, I know nothing about lighting layouts, the talk of Lumens confuses my mechanical brain to no end.

If you want a better understanding, start reading:

http://en.wikipedia.org/wiki/Lumen_(unit)

I need help finding out if what I have planned is overkill (no such thing right?) or if I am on the right track.

The short answer is, you're at least bordering on "overkill"; but IF you set up the switching appropriately (and maybe tweak the layout a bit), you won't be ridiculously over the top.

Garage will be attached to house and used for normal vehicle maintenance, small RC hobby work and man cave beer drinkin gathering point. It will be roughly 36'x35'.

Part of the problem is, each of those three things (at least ideally) requires a vastly different lighting strategy from the other two. For general vehicle maintenance, your general lighting in the vehicle areas is paramount, followed closely by appropriate task lighting for those pesky areas like under the hood and under the car. The RC car/plane/whatever work is almost completely dependent on the task lighting at your workbench. And the "Man Cave / Beer Drinking" part generally wants very subdued lighting, particularly if there is a TV involved.

The picture is busy I know but you can see what I have planned for lights, storage, work areas etc,

It's also almost completely unlabeled; so I can only guess at what some of the items are.

looking to use (32) 4' Florescent, 2 bulb fixtures.

Based on the raw square footage (which I guesstimated at about 1,137.5), that would work out to about 157.5 source lumens/ft.^2. That's more than a little on the high side. But you WILL lose some of that down at working height; and as JoeFin noted, at least some of it is being almost completely wasted due to placement issues anyway.

It also looks like you're trying to make (some of) the general lighting do double-duty as task lighting (for example, the four fixtures which appear to be located directly over the workbenches in the upper-right corner. That's almost always a bad idea. First, there's the upper-cabinet (or shelf) problem that Joe mentioned, by the time you get the lights moved far enough from the wall to do a decent job of illuminating those cabinets or shelves, you're now working in your own shadow with respect to the benches themselves. Second, you don't necessarily want to have to run a ton of general lighting just to light up your workbench, especially when you're only fiddling with RC stuff or similar.

Let me know what you think.

I think you need to better define exactly what you're going to be doing in each specific area of the garage, then let the lighting design follow from that. For example, you're showing what appears to be a 16'-wide overhead door serving the right-hand side of the space; yet only one vehicle is parked there. Is this REALLY how you plan to use the space? If so, Joe is right: That center strip of fixtures is a near-complete waste. And either way, at least some of that strip AND the ones on each side of it will be blocked by the overhead door when open. That latter problem also applies in the other bay. Which of these areas is REALLY going to be the primary vehicle workspace? That's where to concentrate the lighting; areas which are simply car-parking spaces can get by with much less.

Also, given all the things you're showing (compressor, welder, drill press, lots of lights, and presumably a whole bunch of other things you didn't detail), you ARE going to want a sub-panel. While it's not strictly required in an attached garage, installing one will make everything else easier.

As long as this is still in the planning stages, let me throw out a few thoughts not directly related to lighting...

You're also showing motorcycles and a slop sink in the upper-left quadrant. Normally, these two things don't go together all that well (most bike owners want to keep them as pristine as possible; adjacent to the parts-washing area isn't very conducive to that). Also, how are you getting the bikes in and out of there? Snaking them all the way from the front door(s), playing "Dodge-'Em" with whatever lies between on the way? If that's really where you want to store the bikes, an exterior access door right there (it needn't be a "full size" overhead door; a center-opening pair of 30-inch service doors will do nicely) will make life easier in the future.

Per your profile, you're in Wisconsin. So presumably, you ARE planning on some sort of heat for that space. Given that, I'll ring the bell again for:

A. - Insulating the **** out of the slab (at least 4-6 inches of high-R-factor polyisocyanurate foam under the slab AND all around it to form a thermal break with the footers).

AND...

B. - At least lay in the PEX tubing for a future in-floor hydronic heating system, when you pour the slab. If the budget can't support the whole system right away, just let the tubes run wild (and a little long) near the area where the manifold will later be installed (tape up the open ends to keep them clean if it's going to be awhile). There is absolutely no question but that in-floor hydronic is THE best way to heat a garage/shop; and while it is relatively cheap to do these things now, it's near-prohibitively expensive to do them later.

Which brings us to...

Between the heating system, the compressor, the electrical sub-panel, etc., you probably ought to set up a small-ish dedicated "Mechanical Room" somewhere within that space. This will not only help keep things neater & cleaner in general, it will help control the racket from the compressor. If you use framed construction (as opposed to block or other forms of masonry) to build this room, DO insulate the walls between the mechanical room and the garage proper (for noise as well as thermal considerations)

Thanks the responses guys.
I’ll try and answer some of the questions, and better explain what the space will be used for.

JoeFin,
The “vision” is to have some combination of shelves/overhead cabinets. I have removed those lights in question, not sure what I was thinking when I put them there, thanks for mentioning that issue.

I have removed the center row of lights in theNo.2 bay as well. I also adjusted the layout of those remaining to address the door hiding them issue.

Thank you again.

2ManyProjects,
WOW, some great stuff, much I never thought about or missed on completely.

Let me try and clarify what the space will be used for.
The vehicles will be parked as you see them, wife on the left, single stall and myself on the double stall side.
The main work/maintenance area will be the right double stall area. This will be used for vehicle maintenance, washing and detailing vehicles, small welding projects and most other “dirty” work needed to be completed.

The left stall will be parking only for the most part.

The area where the cycles are parked will eventually be a photo area for RC projects and future game area, IE pool, darts, etc. The cycles are actually scooters, parking there and getting them out will not be an issue and they stay out of the way there.

The work bench area will be for bench projects, mostly RC (soldering, brazing, assembly and some welding) this will also be the Bar/Game TV area with stools and a TV in the upper corner. I have removed the lighting from here. I do have some hanging bar lights that will go up over the “bar” section, the rest of the lights will be under cabinet and/or task lighting.

I do apologize for the first picture. I am attaching another cleaned up and labeled version. I do hope this helps.

I still have some questions on light placement and zones.
The side walls will be 3’ from the garage doors, is this enough space to hang the lights as seen below?
What would you suggest on zones and do you see any “dead” spots?

Thanks again to the both of you for taking the time to try and help, I will be reading up on the link provide and hope to better my knowledge a bit.

Red, that looks like a great garage/workspace, and you're getting the right answers from 2Many, so I don't have anything to reall add. But I'd like to know what CAD rogram yo are using for your garage layout. Is it something cheap (free?), simple to learn, or are you an experienced CADesigner? I have a friend that is getting ready to build a 40x42 in early 2014, and this kind of program could help him immensly.

Good luck on your project.

JoeFin,
The “vision” is to have some combination of shelves/overhead cabinets. I have removed those lights in question, not sure what I was thinking when I put them there, thanks for mentioning that issue.

Unfortunately, you now appear to have gone too far in the other direction, and have left that workbench/bar area COMPLETELY devoid of general area lighting. Even if you are presuming LOTS of task lighting, you still need SOME general area illumination.

I have removed the center row of lights in theNo.2 bay as well. I also adjusted the layout of those remaining to address the door hiding them issue.

That's an improvement; but this time, you need to take it a bit further. The right-hand run of four fixtures will be at least half-blocked when the door is up. And since (per your later comments), this is the primary vehicle maintenance area, that's not good. You're really tight on space between that edge of the door and the wall; so your placement is at least somewhat understandable; but it's still far from ideal. I would suggest moving them out to JUST past the edge of the door (which would put them about 2.0-2.5 feet off the wall). Have you yet determined your ceiling height? In general, higher is better (at least up to a point); and if you have more than 8.5-9 feet to play with, it is probably worth specifying to whomever installs your overhead doors that you want the tracks to run extra high (so the door is held within 0.5'-1.0' of the ceiling when open), which will in turn make dropping the lights to just below door-track level (so they can throw some light into the area "covered" by the door) more feasible.

I would also put at least a couple fixtures running "crossways" near the "rear" of the main maintenance bay, to better illuminate the "business end" of the vehicle you're working on (and especially to throw some light into the open engine compartment).

2ManyProjects,
WOW, some great stuff, much I never thought about or missed on completely.

You're welcome. Better to raise those issues now, than after you've already carved some things into granite (or concrete, as the case may be :rolleyes:).

Let me try and clarify what the space will be used for.
The vehicles will be parked as you see them, wife on the left, single stall and myself on the double stall side.
The main work/maintenance area will be the right double stall area. This will be used for vehicle maintenance, washing and detailing vehicles, small welding projects and most other “dirty” work needed to be completed.

The left stall will be parking only for the most part.

In which case, you really don't need all that much light in the left-hand parking bay. The "spill-over" from the row of four fixtures between the two bays will provide at least most of what you'll need in this area. But if you still want to brighten up that side a bit (and particularly for illuminating any wall-hung storage there), two fixtures where you're currently showing three should be more than adequate.

The area where the cycles are parked will eventually be a photo area for RC projects and future game area, IE pool, darts, etc. The cycles are actually scooters, parking there and getting them out will not be an issue and they stay out of the way there.

Fair enough. But note that if/when that pool table goes in, your lighting needs will change yet again. In the meantime, if all you're REALLY using that space for is storage, then either two twin-tube fixtures, or perhaps 4-6 single-tube fixtures (so that they can be laid out to more evenly cover the cabinets & shelving) will likely be sufficient. HOWEVER... Fluorescent lights will NOT make any photographic work you do there easier -- far from it, in fact (fluorescent ***** at rendering color; and matching photo-flash to it, such as for fill-flash applications, is next to impossible). If you're semi-serious about making that area into a mini photo studio, I would suggest some high-CRI halogens with tightly controlled color temperatures, maybe in track-light form, so you can easily adjust the aiming as needed at any given moment. But then, for REALLY serious photo shoots, you will near-certainly avoid be using ANY of the room's ambient lights anyway, in favor of a set of photo floods or strobes.

The work bench area will be for bench projects, mostly RC (soldering, brazing, assembly and some welding) this will also be the Bar/Game TV area with stools and a TV in the upper corner. I have removed the lighting from here.

Yeah; but as mentioned above, you need to put SOME of it back

I do have some hanging bar lights that will go up over the “bar” section, the rest of the lights will be under cabinet and/or task lighting.

I'd have to see those "hanging bar lights" to make any real judgement about them. But I strongly suspect that these would provide mostly the sort of subdued, warm "downlighting" which might be suitable for when the area is indeed being used as a bar, and for TV viewing. If so, then you'll still want at least one or two fluorescent fixtures on the ceiling for when you're actually trying to work there (and to cover the "No Man's Land" between the workbench area itself, and the scooter-storage/pool-hall/photo-studio area).

I do apologize for the first picture. I am attaching another cleaned up and labeled version. I do hope this helps.

It's a definite improvement.

I still have some questions on light placement and zones.
The side walls will be 3’ from the garage doors, is this enough space to hang the lights as seen below?

Yes.

As a general rule, assuming "typical" wall storage & similar, you want the lights at least 1.5 feet off the wall, if at all possible; 2-2.5 feet is generally better; 3-4 feet is about max., unless the ceiling (and thus the fixture-mounting height) is exceptionally high. In all cases, this assumes that you're NOT moving them so far away from the walls as to let them be blocked by overhead doors and such.

What would you suggest on zones and do you see any “dead” spots?

I've already mentioned the "No-Man's Land" near the doorway to the house.

Normally, in a space of about this size or smaller, I would not get too hung up on (or even seriously suggest) "Zoning", per se. However, in this particular case, there are such clearly demarcated separate areas for various activities, that a zone-based approach to both the lighting layout itself AND the switching is clearly called for. Which brings us to...

Given all you've got going on in there, and the complexity of all the different activity-defined lighting permutations, I would suggest that you strongly consider going with Insteon for the switching & control system. This will not only make it easier to maintain flexibility; it also "future proofs" you to a certain degree, since at least most of the "switch" assignments would be only "virtual" in nature (and could thus be changed on-the-fly if desired). Plus, you're showing at least three entry-point locations where you would want switching control (i.e., adjacent to the two service doors and on the short "jog wall" between the two overhead doors); which means implementing conventional "3-Way"/"4-Way" switching for everything would be relatively complex & expensive. With Insteon, a single keypad (two at the most) in each of those locations can take care of everything; and the wiring becomes much simpler.

And finally, I'll again beat the drum for working a smallish dedicated "Mechanical Room" into the plan, for all the reasons already explained.

I had thought I went too far the other way. I've made more changes as you'll see below.

Ceiling will be 9' so I will look into the mounting you have suggested.

I think I have everything moved/added as suggested. The layout looks much better to me now.

I also should have mentioned, the lighting in the future game/photo area is not shown. I do know this will be a very different type and style and that eill be addresses at a different time. I will be adding outlets now so the area is ready when needed.

I will look into the Insteon for switching, this sounds like a better option than what I had planned.
My initial thought was to have a single switch by the service door and center overhead doors which would turn on enough for walking through to house and a bigger switch panel by house door controlling all lights.


As for the mechanical room, not going to happen. The limited times I use my small compressor and the small electrical panel if needed will not require it.


Here is the updated plan, again, thank you very much for your help, it is greatly appreciated !!
