It depends on the led bulb in question (how many watts it is). Since they are 12V DC, the math for a 1 watt bulb sorts out to
amps=watts/volts
amps=1/12
amps=0.083333333333
So, for 12VDC you can take the total number of watts, multiply by 0.083333333 and that'll give you the total amps.
for single phase AC, the formula is pretty much the same except it's amps= watts / (power factor x volts)
