you will need 15 amp breakers for each of the 1000W HIDs. ohm's law states I=V/R or current = voltage divided by resistance.

120V/1000W= 12amps

15A breakers are designed to let you put a 12A load on them. so 2 for the lights, and another for the a/c and another accessory perhaps, but check the power consumption of the a/c. and then another circuit for the rest of your accessories.

so you will need to get those 20 extra amps.
