How to align the voltage for LED lights?

I hung a garland, but it flickers, it’s unpleasant to my eyes. How to balance the voltage? It is connected directly to the 220V network, no more buttons and electronics.

It's hard to think ...))) January 1 ...))))
But aren't they really 25? Indeed, the garland itself is a half-wave rectifier without a filter ...

that is not, these are not flickering. It seems Italian. The cable is thick, the insulation is good, it doesn’t look like a tie. Just white LEDs, no effects.

Holiday greetings!

So this is probably Ketai bulbs (low voltage). So they should flicker, it’s New Year’s ... decoration for.

Not 25, but 50. And it will be - yes, 100.

Just a rectifier with a filter cannot be, it will be 310 V. We need to measure how many milliamps a garland consumes when powered in the usual way, on the basis of this, calculate the resistance and power of the limiting resistor. So that the current through the garland becomes the same as before completion, then the voltage on it will also become the same automatically.

At the input of the garland, a diode bridge must be installed, observing the polarity, then the LEDs will flash with a frequency of 100 Hz. This, for the eyes, is not noticeable.In your case, the LEDs flash at half frequency (25 Hz).
