The room is directly above my garage. The dead end of the attic has
some plywood, then it looks like I can see the inside of the siding on
the house (small hole in the plywood lets me see what's next to it).
When you look at the room from the street, you're looking at a dormer
in the center of the "roof" covering the garage. So...the attic ends
where the garage roof begins, and there's open air space between the
edge of the attic and the dormer roof. Essentially, the roof on top of
my ceiling is only covering this room...and there's no "attic" access.
I've had luck finding the joists, and have a good idea of where I'm
going to hang the fixtures now. As for grounding, the 3-wire cable
that I purchased has a ground, neutral and hot. Ditto on the fixture.
Regarding grounding...will ground the fixture ground wire to the box
first, then connect it to my cable ground with wire nuts. This was the
recommendation of the electrical guy I talked to at the hardware store.
The light itself has circular mounting box that the wires are housed
inside (your typical mount for many lights), along with the support
bars that are attached by screws to the electrical box in the ceiling.
The fixture is actually 4 lights that are suspended from a curved rail
that hangs below the mount. Kinda difficult to describe...bought it at
Lowes, but no picture on their web site.
