Ok now you had better figure out an accurate load for that same cable at 12 volts, or you are going to get yourself into a heap of trouble fast in our realm.

Again in general, a 12 gauge copper wire is allowed to carry 20 amps. The formula for converting to watts would be 120 volts X 20 amps = 2400 watts x .8 = 1920 watts. The .8 multiplier is a derating factor that applies to a circuit that we would expect to run more than 3 hours which would certainly apply to lighting.

Right you are. So at 12 volts it would come to 192 watts of lighting.
