Question:

How is the rated current of the LED street lamp holder?

How is the rated current of the LED street lamp holder?

Answer:

For example, the rated power of the lamp is 220W, the rated input voltage is 220V, and the power factor is 0.9Then the rated input current is 220W/220V/0.9=1.11A
The rated power of the lamp cap is divided by the input voltage and then divided by the power factor.
