You can also eliminate flicker by not using PWM, and instead using a high switching frequency DC power supply with a clean stable output current. Obviously it

Obviously it costs more, but I wish manufacturers would just do it.
- davrosthedalek 1y agoConceptually, that's not far away from PWM + filter, except maybe for the closed loop.
- Saris 1y agoYeah that's true, LEDs do need a closed loop for current regulation in a high efficiency setup, so might as well use it for dimming too.
