Not so fast, that depends on what load you are running. If you still have all of your original incandescent lights you'll have a big load. Just 12 of them (6 double fixtures) on at one time is 18 amps, and over 15 feet of 10 gauge wire that's a 5.6% voltage drop - which is too much. Even if you only run 6 bulbs, if you add on a fan and/or water pump you'll be back into high-amp territory.
