Can anybody specify how about PWM (flickering and sound (whine)) mentioned in first message

I think he mentioned that on Low and Medium you might encounter a slight visible effect of PWM if you try hard but that you are more likely to hear a very low sound of the vibration. I think that’s pretty good.

Does S2+ have any PWM?

Thank you for answer, my english dont are very good.

About S2+
In here mentioned, that “All Convoy lights with 7135 drivers use 4500Hz PWM” I think that taken from candlepowerforum so S2+ 4500Hz and E2 3900Hz
