Why is the power of the LED lamp more than the nominal?
This is what haunts. There is a light bulb with an operating current of 0.055 A, an operating voltage of 220 V AC, as I understand it, current, and it consumes 6 watts. So if you consider the power according to the formula p = iv, then the power consumption is 12 watts. And in document 7 it is written. Is this normal at all? Will the lamp burn brighter or something else? Please explain how it works.

In addition to active power, LED lamps have a reactive, that is, a working current - includes both the active and reactive components. If we neglect the reactive power (its small percentage in lamps) and calculate the power, then 0.055 A * 220 = 12 W. There are two options - either the error of the device and in reality the current is less, or the power is underestimated, which most likely is in fact. Typically, manufacturers of LED and fluorescent lamps specifically write deliberately less power - the "marketing move", supposedly a lamp that is very economical to buy better.
If we assume that the current consumption increases in proportion to the mains voltage, and these 0.055 A are indicated for the highest voltage of 264 V, then the lamp consumes 7 W at 180 V. That is, the power is indicated for the lowest mains voltage, and the current consumption for the highest. Everything fits together 🙂
Finally: if there is the simplest capacitive current limiter, then 80% of the consumed energy is reactive, which is lost, and only 20% is converted into light. Accordingly, if there was a different type of power supply, the lamp could give 3 times more light 🙂
