Well, I bought a big unibit to bore holes in the fixture to run the pvc (see other thread). It's going well, just to slow for my liking.
I'm also switching them over from the house panel to the garage panel, so that's going to take some time, and I also have to remove the existing lights.
My plan is to put up all new lights I can, just leave a long length of romex on the last one I can do, and put a plug on it for now so I can plug it into an outlet. (Yeah yeah, I know, but it's only temporary so I can see while I remove the old lights/wiring/switch box and install the new stuff.)
Then I'll get it wired from the breaker to the switches, install the rest of the lights, and just be down to killing power for a few minutes to pigtail the rest together.
I'm running two switches, two lights on one for basic stuff when you're just grabbing tools etc., for the house, and seven lights on the other. All 9 lights will be on one breaker to save room, they only draw .8 amp each, so even with 14 gauge and 15 amp breaker, I'm well in spec.
After that I need to run a new outlet for the garage door opener, and I'll be 100% free of the house panel.
