    Hello,

    recently I purchased 4 pack of shelly vintage smart bulbs model A60 and I have problem with strobe effect when dimming.

    Everything works fine when bulb is somewhere around 85%-100% of brightness, but when I start dimming brightness lower strobe effect starts to appear.

    This is very noticeable when you move your hand or bulb and you start to see this strobe effect.

    I tried with all 4 bulbs on different places, and same thing happens. Also I have updated all bulbs to most recent firmware, but there is no change

    Did someone experience same problem with this bulbs?

    Thank you in advance!

    Same problem for me.

    What is the PWM frequency of the Shelly Vintage bulbs? I am specifically curious about the "ST64" and the "G125" because the light they emit makes movements of objects lit by it seem "jittery". It seems like the Frequency is too low, so that smooth motion gets split up into many still images, almost like being lit by a stroboscope.
