I may be wrong, but I think you can calculate it by:
Watts = Volts x Amps
So:
Amps = Watts / Volts
Thus, if you're running them on a 240 volt circuit, it resolves to:
A = 200 / 240 = 0.83 Amps

If each spotlight is rated at 100 watts, together they would use 200 watts. To convert watts to amps, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V in a household setting, the double 100 watt spotlight would use approximately 1.67 amps.

How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
How many amps does a 65 watt light bulb have at 120 volts?
To calculate the amperage, you can use the formula: Amps = Watts/Volts. For a 65-watt light bulb at 120 volts, the amperage would be 0.54 amps.
How many amps in a 4400 watt output with 120 volts?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many amps do you need for 580 watt 120volt?
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
How many amps do 8 40 watt fluorescent lights take?
Assuming each 40-watt fluorescent light takes around 0.33 amps, 8 lights would take approximately 2.64 amps in total.
How many volts in a watt?
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
How many amps is needed to run a 1450 watt coffee maker?
A 1450 watt coffee maker will use around 13 amps at 110 volts.
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
How many amps do you need for one 1200 watt sub woofer?
you just need one, a general rule of thumb is that the wattage on your amp should be double the wattegae on your sub, hence if you have a 1200 watt sub you'll need a 2400 watt amp
