Learn how to calculate the amperage of LED lights using wattage and voltage, and how to compare them with incandescent bulbs. Find out the amps of different LED lights, such as 100W, 60W, 40W, and more.
4 Αυγ 2015 · How Many Amps Does a 100-Watt Light Bulb Draw? At 120 volts, the most common household current in the United States, a 100-watt light bulb draws 0.83 amps. To calculate the amperage of a light bulb, one must divide the number of watts by the volts powering the circuit.
A 100-watt light bulb at 120 volts will draw 0.83 amps of current. Convert Volts to Amps using Resistance Ohm’s Law provides an alternate formula to find volts if amps and the electrical resistance are known.
Amp draw is a simple mathematical calculation. Divide the total number of watts by the system's volts. For example, a 100-watt bulb in a 12-volt system will draw 8.3 amps. For systems with multiple lights, you would add up the wattage of each light and divide that by the system's volts.
The number of amps that an LED light draws depends on the wattage of the bulb and the voltage of your home’s electrical system. On average, 9W and 15W LED light bulbs will use 0.075A and 0.125A, respectively.
