> Nah, LED lighting generally uses at least 200 Hz at a minimum.

Eh, they use what they can get away with. Nobody is out there policing flicker rates. Especially when you add a dimmer into the mix, there's a lot of room between good and bad, and when you're at the hardware store buying bulbs, there's not much to indicate which bulbs are terrible.

Lots of people don't seem to notice, so the terrible ones don't get returned often enough to get unstocked, and anyway, when you come back for more in 6 months, everything is different even if it has the same sku.

Not only flickering, but lots of other information about internationally available brands, including cheap Chinese stuff: CRI, real power use, etc.

Actually, Energy Star and California's Title 24 have flicker standards. They may not go as far as some people like, but you can look for these certifications to know that a bulb at least meets a certain minimum standard.
