Why would a manufacture print false information on an LED light? The brightness of a light is measured in lumens. That number is printed on an LED to tell you that the LED bulb will give you the same brightness as a 60W incandescent bulb.īut that raises a question. ![]() That example sounds perfectly reasonable, but it doesn’t tell you everything.Ī 60W LED bulb doesn’t use 60W. The example above shows you the number of amps that a 60W bulb uses. However, you cannot trust the wattage printed on an LED lamp because it isn’t accurate. To calculate the amperage of an LED light, you have to first determine the wattage of the LED lamp. The brightness of an LED light is fascinating, especially when you compare it to the brightness of an incandescent lamp. They are also far more efficient.Ī 10W LED light can deliver the same brightness as a 60W incandescent bulb. LED lights use less power than incandescent bulbs, but they are just as bright. That is to say if you know the voltage and wattage, you can calculate the amperage. If you have two of these values, you can easily calculate the third. Many European countries prefer 220-250V power supplies. Homes in the US utilize 120V power supplies. Your home’s electrical service is measured in volts. You can turn a circuit breaker’s amp rating into watts, but it is easier to use amps because the rating printed on a circuit breaker is presented in amps. The amperage is also vital for people that need to select a circuit of appropriate size for their home. Therefore, to identify the correct size breaker for a circuit, you must determine the amperage of all the devices using that circuit. The amperage matters because circuits are rated in amps. The amperage shows you the volume of current a power source can provide. Every bulb you buy has a rating presented in watts. ![]() The wattage tells you the amount of power a device uses. But how much power do they actually use? How Many Amps Does A LED Light Use?īut how to calculate these figure? The resource took into account the wattage, amperage, and voltage: LED lights are supposed to be more efficient than their incandescent counterparts.
