Led Christmas Lights

Certain LED lighting uses a capacitor to avoid the stroboscopic effect given the speed of this lighting.
Does the light slowly dim or stay on all the time?

the sensation it was a flash: when I pressed the strong light switch (ripping up a condo?)

Renaud67: your switch is behind the transformer? (ie in the order: wall socket-transformer-switch-LED)

If so, it is your transformer which emptied its capacitor in the LED when you pressed the button.

Besides, if you can, put the switch before the transformer: it will prevent it from consuming when you turn off the light.

Surely a capacitor discharge.

An interesting thing is that on a string of 200 lights, I have a voltage return of plus or minus 50 millivolts in full daylight, we know that a diode can give the solar panel effect.
For the purposes of the test, I am going to check in the dark tonight if I have the same result, because here it is 10 am.
It can be a magnetic effect in the wire.

I confirm later.
