My shop is 32' X 60' w/10 48" 4 tube fluorescents. A few years ago I replaced all the ballasts w/electronic ones, 1 of the electronic ballasts replaces 2 of the old ones.
The electronic ballasts power T8 lamps instead of the old T12s. Each fixture now uses about 85% less power than previously.
8 of the fixtures are spread out on the ceiling and I put individual switches on them so I only turn on as many as needed for the area I'm working in.
The other 2 fixtures are over the welding/work bench w/their own switch.
