I just had my service panel upgraded and now I plan on redoing the
lighting in my garage. I have a 26' x 21' garage and I plan on
installing 9 t-8 lighting fixtures (3 rows x 3 deep)(see configuration
below). The question I have is: does it matter how I run the wiring
to each fixture? I am thinking of running the wiring in an 'S'
pattern to each fixture. Or, does it make more sense to run 3
separate T's coming off of the main line? I also thought about running
two separate circuits for the lights. This way I could increase or
decrease the lighting as needed. Which makes the most sense?
