A lot of cheaper ones do half-wave rectification on the mains voltage, so they flicker at 60hz (or 50hz). Slightly "better" ones will do full-wave rectification

A lot of cheaper ones do half-wave rectification on the mains voltage, so they flicker at 60hz (or 50hz). Slightly "better" ones will do full-wave rectification but no smoothing, so they flicker at 120hz (or 100hz).
A crap ton of decorative "Edison-style" bulbs have this cheap or non-existant circuitry in them. Buying from Amazon is a huge gamble. I have slow-mo video of disappointing lights.
The quality bulbs will power the LEDs from a smooth DC voltage and not flicker.
- saiya-jin 4y agoExactly this - in age of most decent phones having no issue recording 1000fps videos, just record one with your lights. Heck even 240fps is enough. Suddenly those nice lights may not seem so nice anymore. I wouldn't be surprised if this has some quiet smallish long term negative effect on our brains and eyes. In same vein as 24fps-is-enough-for-everybody was a lie
