Being aware of LED flicker and having been to places with both 50 Hz and 60 Hz AC, the places with 50 Hz are definitely worse. Extremely easy to perceive. Plus, it can be difficult to take photos under this light. Also, most of the "Edison-style" LED bulbs on the market use really cheap drivers. This is especially true outside the U.S. where you can get an LED "filament" with integrated half-wave rectifier. Thankfully UL is not allowing this crap in the U.S., but Edison-style LEDs here still (mostly) use very cheap driver topology. I'm on a mission to make lighting healthy. That's why I launched Bedtime Bulb: https://bedtimebulb.com/ https://bedtimebulb.com/ We have the lowest flicker of any bulb I have ever seen, even less than those claiming to be "flicker-free."
