Attached are some pictures of the lighting setup in my new garage.

The system uses GE RR7 low voltage control relays. These are latching type relays, activated by a short pulse to an ON or OFF coil. They then mechanically stay in the ON or OFF position.

The control box is designed to keep the high and low voltages separated. There will be light switches at each door.

Right now, the main panel only has a 125 amp breaker to the transfer switch and sub panel, along with the government mandated GFCI outlet right by the panel.

The sub panel is connected through the transfer switch. It only has outlets and lights now.

The lights are temporarily wired directly to the breakers, but the control circuits will be connected next week.

The lights are thirty five fixtures, each with four 4-foot lamps of 32 watts. The lights are on three zones. The total light wattage is 4480.

The fourth switch is for outside lights over the man doors, generator, and large doors.

Pictures with the lights off and on will be in the next post.

I used low voltage controls so that I could use Allen Bradley lighted mushroom buttons as my light switches. Gives an industrial look.

Holy **** that's a huge garage!

The lights are all std voltage though right. So the have to be wired to the control center no matter what. Then low voltage wire can go from control panel to wall switches. Just asking as it doesn't seem like a big savings but I like the idea. Just trying to learn more. Maybe I'll search some more rather than bothering everyone with seemingly simple questions. Thanks for the info though. Love the forum so far.
