Filament LED bulbs usually flicker at 120Hz (with high duty cycle) and Christmas LEDs at 60Hz (with a short duty cycle). Other LEDs are, indeed, high frequency like you describe and are perceptually effectively constant.
- vidanay 7y agoThe filament in a filament bulb doesn't fully cool down when the voltage crosses to zero, so that smooths them out a lot. Sorry...I just noticed you are talking about filament LED and not old fashioned analog filament bulbs.
