My 24'x36' post frame garage is under construction. I'm planning the wiring and lighting. I'd like some opinions on the types of fixtures and bulbs I should use. The garage will not be heated so whatever I use needs to perform well in cold temps.

I will be installing two groups of three way switches (three switches in each group). One group between the two vehicle doors and the other group at the man door which is closer to the rear of the garage. My plan is to have three lighting zones which can be controlled from either location.

I'm considering LED due to lower energy use and good cold weather performance. I was thinking maybe 12 of these and put them into standard 4' fluorescent double bulb fixtures and install two in each zone. These bulbs have 1600 lumens each so twelve of them will yield 19,200 lumen total. Is that enough for 24x36 garage?

What are your opinions on other garage lighting ideas. I'm open to any suggestions.

That's the rough equivalent of a 100 watt incandescent bulb for every 72 square feet. Probably adequate for general lighting but Kurt's right, add some task lighting in there for work tables, etc.

What's the ceiling height?

9.5' to 11' ceiling height. The front third has bottom chord truss and the rear 2/3 has scissor truss. I wanted to gain some extra height for possible 4 post vehicle lift at the back end of the garage. Bottom chord trusses near the front provide some limited storage but also facilitate supporting vehicle door tracks and door openers.

I like the cheap clamp on types for my stationary power tools and one of those gooseneck jobs for my bench.

I went LED in the apt. building; I got 4 times more light for about 1/4 the previous cost. Le Depot de Maison has some really good prices on LED stuff nowadays; I put 7 LED overheads in the boiler room...bright as can be and about $15 each.

Got Light?

Here's one fixture with 2 Phillips T8 LED tubes. The tubes are 14 watts each so 28 watts per fixture. My plan now has 3 rows of 3 for a total of 9 fixtures at 252 watts total. Each row will be individually switched at both the man door and vehicle doors.

I'd put the outer rows on a single switch and the inside row alone on another switch.

With LED, I might even put the center fixture on it's own switch and the remaining ceiling fixtures on another. Gives you sort of a 'night' light.

What are your headers bearing on?

Roof loads carried as follows;

10 trusses total 4' on center including the gable trusses.

The four trusses at inner post positions are bearing directly on the 6x6 laminated Tuff Post which are notched at the top for the bearing spot.

The gable trusses are bearing on the headers which over hang the corner posts. The end gaps are filled with 2x6 and nailed in with 16d to extend the bearing surface for the gable trusses.

The remaining 4 trusses are bearing on the headers and are fastened with 2x6 pieces which are sandwiched between the header gaps.

Two 2x12 stacked as header for vehicle door openings and nailed with 16d including 2x6 nailed to post for additional header bearing. I think the double stacked 2x12's will do good in preventing wind from racking the building.

Nails. Ain't got any weight on them anyway.

I guess John doesn't get termites in his part of the country. No one here has built a shop on dirt in over half a century.

We have Eastern Subterranean here. Unlike you which also have the much more voracious Formosan.

The Tuff Posts have lifetime warranty for the original owner but I'll get my pest control friend to do preventative treatment anyway. http://www.tuff-post.com/
