Flickering on Paulmann URail Spot Circle?

Connect the Paulmann, for example, to a UPS so that you have a clean voltage. If it still flickers, the problem is with Paulmann. If not, it's your electrical system.

Huhh, but not everyone necessarily has a UPS at home. In any case, as Rick already said, narrow down the error further. Does it flicker everywhere? Maybe try it at friends' houses. Does it flicker all the time or only at certain times?

Wrote yes, for example. There are also other possibilities of a voltage source with a smoothed signal.

Isn't it a design flaw anyway if the LED flickers even in the brightest mode? One would think the PWM is off in the brightest mode.
