You need to run a sub panel then you can wire everything into it. If your ballasts are running on 220v then 30A should be fine as the lights will likely draw about 17A (guestimate) 10 g wiring is good for 30A also. 30A double pole breaker is only 30A not 60A. Double pole breaker adds two 110V lines together to give you 220V but the amperage stays the same. If you plan to run lights from 110V then 30A won't cut it cause the lights alone will draw over 30A.
