LEDs still have PWM flicker and buzzing problems. This is unpleasant, inhibits focus, and makes them inadequate for me in all cases. Perhaps the fancy "smart bulbs" aren't as bad, but I don't have $125 for a single light bulb. I also don't want to fiddle around with my lighting and by multiple $125 bulbs until one works. I just want to put in a bulb and be done. The only lighting which has successfully done that for me has been incandescent or halogen.

If you see flicker, then you bought an LED lamp with a wrong kind of driver. You can dim LEDs to zero without any visible flicker if the circuit is designed properly

Smart bulbs often aren't any better than cheap ones. But there are people doing high quality ones (high CRI, and no flicker). These ones for example: https://store.waveformlighting.com/collections/a19-bulbs/products/centric-home-full-spectrum-flicker-free-a19-10w-led-bulb https://store.waveformlighting.com/collections/a19-bulbs/pro... There are cheaper ones that are good too, but I can't remember the name.

You must be getting the absolute worse brand of LED lamp to have PWM flicker or using a crap dimer (or alternatively, have vision way beyond 60fps) I have none of those problems with LED lamps that certainly didn't cost $125 (more like between 5x and 10x cheaper) and none of them buzz

  > You must be getting the absolute worse brand of LED lamp to have PWM flicker or using a crap dimer Related: is there any good source of reviews for LED bulbs that go into flicker (I seem to notice 120Hz flicker) and CRI? My local hardware store stocks a relatively paltry selection of bulbs (all built to cost), and I'm reluctant to experiment with the medium-size orders necessary to make shipping worthwhile.

Not all use PWM.
