There's burgeoning movement called "PWM sensitive"[1] that's opposed to (cheap) LED lights.

The frequencies that they claim affect them are disputable but the flickering in some cheap LED lights is real. Badly/cheaply designed electronics can have flicker as bad as 50 Hz if they use half bridge diode rectification only (e.g. that time I was passing through Geneva airport and the Christmas lights flickered in my peripheral vision)

yep, i had one led stripe with a controller with a flickering that was kinda invisible to the eye, but very noticeable on camera.
