How many amps in a string of Christmas lights?

Answer 1

It depends on which lights get used. A 100-count string of incandescent mini lights runs at 40 watts, while a 70 count of 5mm Wide Angle LEDs is approximately 4.8 watts total. In fact, because incandescent wattage is 80-90% more than LED wattage, the cost to power an incandescent can be up to 90x greater than powering an LED.

Calculate Amps by dividing total wattage by 120 volts (US household outlets carry 120 volts)

So about .33 for incandescent and about 4 for LED.
