I have some metallux 6 bulb fixtures to install in new garage.

I was told to hang one foot below ceiling which will be drywall.

I understand to suspend lights with chain and hooks

What is the best way to concealing the wiring going into fixture?

Should I mount ceiling boxes? Or just drop romex thru drywall?

I have 6 fixtures, I am running 2 circuits.
In circuit will be the 2 bulb ballasts in all 6
The other circuit will be the 4 bulb ballasts

So there will be a few wires.

Any advice is appreciated. The ceiling is wide open now and rough in inspection is coming up in a few days.

I drywalled, but even if I didn't I'd do the same; Get the depth adjustable new work boxes, and attach them where you want the lights. If you insulate and drywall, they are all set. If not, they still properly contain the wiring. I did leave a bit of slack in each wire in/out of the box so I could adjust the depth without any snagging or pulling of wires.

I also didn't hang my LED fixtures from chains - I just used an S hook directly on the mounting point. Just enough space between the ceiling and fixture to hold the extra wire.

There will be insulation and drywall.
My question is what to do with the wire 12" between ceiling and light fixture.

Put a box on the ceiling then flex to the light or sleeve the wire in some flexible conduit if you don't want to have a box on the ceiling.

If a fixture is chain mounted, the wire will need to be stranded.

Thank you! I learn something almost every time I visit GJ. Timely info, since I will hopefully be starting on the lighting for my garage soon.

Thanks Norcal. I had wondered about the flex issue and asked the electricians at our building how they hung lights. They run MC along one chain and apparently that passes inspection. It's probably not a big deal but I was planning to run black cord (SOOW?) to the ones I will install soon.

Unless the MC cable is stranded, it's not code compliant to use it for chain mounted fixtures.
