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).

You won't need furring strips, Bill. Fixtures will screw directly
through the drywall ceiling into the joists. That's one of the reasons
I suggested that you run them that direction.


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...

Yeah, and don't forget to sand them to 4000 grit. sigh
