LED lights with a meter, about how much W?
Different LED light bands are different, which need to be calculated according to their current and voltage, so as to calculate the power.
Power is the measure of the transmission rate of energy. In a DC circuit, it is the product of the voltage V and the current A; it is much more complicated in the AC system. Whether they are high voltage or low voltage LED light belts, they convert AC to DC to work.
Each manufacturer because the chip is not the same, will cause the LED lamp working voltage and current is not the same. Therefore, the same band of rice LED lights on the market, their power will vary.
