I have been reading up on LED bulbs and it seems power factor correction (PFC) is quite needed in most designs.
My goal is to achieve a PF greater than 0.9. I am considering using an LED Driver with built-in PFC like Fairchild's FLS0116. From the datasheet of FLS0116 (and attached photo), it's easy to see that the IC ensures that the LED current follows the shape of the input voltage waveform as closely as possible - including where the voltage crosses zero.
My question is: because the LED current is zero every 10ms, will there be any visible flicker?
