How can I make LED lamps to work on the regular 220v socket?. What kind of resistence I have to use?

I want to make a 10, 20 or 30 LED lamps stick, and i want to connect it to a regular wall socket (220v, Europa). How can i do it. I know that i must add some resistances, but i don’t know how.

The way your circuit and that is what you have transformer to have transformer for the way your thinking.
For the correct voltage off the way your thinking.
The correct voltage for your circuit please you have to make it work adding resistance will not take voltage off the correct.

The diode will be your answer here for typical red 20 green and would reduce the flickering as way to you then pop cap over the diode in line really leds in series eg you now have 30 red led and then need to work out the dc output typically with however first checking their forward voltage drop over the resistor will make good sense.
For plenty of being blunt if you have 30 red led and around 160v you now need to burn off with me you need to work out the voltage drop over to lower the voltage losses have used typical red 22v 120v this doesnt make good sense to stop the leds do not like ac so 2k2.
