The ceiling is 9' 2". The garage/shop's only purpose in life is for working on and storing the car. Nothing goes in there unless it's car related.
I have a dedicated panel in the shop, it's not a branch. LED lighting sounds interesting, I'm going to do some research on that. I keep the shop heated in the winter, but only just about freezing.
As for budget, I'm pretty open. Since I'm only finishing off the walls and adding lights to a 24x24 garage, it's not a huge project.
Thanks for the links, guys. I'm going to go check them out.
