It is absolutely amazing all the B/S to relight a 2 car garage, quasi
whore house (stippled ceiling), maybe workshop.

Close to 100 posts, most totally crap.

IES recommendations for a machine shop/wood shop call for 100 foot
candles maintained.

Using 2 lamp fixtures, approximately 19 fixtures are required for 100
FC maintained.

Given the geometry of the room and fixtures, 19 fixtures would be
difficult to maccomplish.

16 fixtures gives a good fit and still provides 71-72 FC maintained.

Run 1 x 4 x 24 ft furring strips equally spaced on 5 ft centers,


Sign posted at a whore house: "Furring strips--Extra!". --anon.


At 24' each, they may cost me a few bucks too. I have to add them to the
material list. Getting them attached to the stippled ceiling without
breaking it ought to be a careful procedure too. I read about using
8-penny nails, but I like my chances better using screws. Should
probably leave 1/8"-1/4" between boards to allow for expansion, no?
That maybe not look so cool if they are staggered between ceiling joists
(as advised).

Still having fun. I plan to attach string between nails, scrape
stipple, nail up the boards, and then wonder whether I should have
dimensioned the 1by4's! The ceiling is, however, rather more suspect in
that category...

nailing or screwing thru drywall into ceiling joists. (4 runs)

Prime and paint when finished to match whore house ceiling.

(Since these furring strips are 30" from the side wall, they will miss
the overhead garage door tracks by at least 12" on each side.)

Mount 4 fixtures directly to furring strips with screws on 5 ft
centers leaving 2-1/2 space at beginning and end of runs and 12"
between for the 3/4" EMT.

Install 1 ft lengths of 3/4 EMT (Thin Wall Conduit) between fixtures.

Pull 12-3 /W/ ground THHN (Blk, Red, White, Green) for each run (L1,
L2, N, G).

Stagger fixture wiring as follows:

Row 1: L1, L2, L1, L2
Row 2: L2, L1, L2, L1
Row 3: L1, L2, L1, L2
Row 4: L2, L1, L2, L1

The above uses two (2), 1P-20A c'bkrs and provides two levels of
lighting, 50%& 100%.

At this point, two (2) wall switches can be added so the c'bkrs do not
have to be cycled.

Don't sweat covering fixtures with the garage door.

At most, two (2) fixtures get covered, but you still get some diffused
light from them.

Enough bull **** already.

Spend a few bucks, you can't take it with you.

Time for the next job.
