Poorly made LEDs actually flicker at 120Hz on 60Hz mains, see my other comment. And it's more like a pet peeve, only below 60 Hz is actually headache-inducing. Unless it's specific circumstances (I couldn't stand a cheap 120Hz PWM RGB strip close to a gaming monitor because I'd see annoying "rainbows" as my eyes dash across the screen). More details in my other comments.
Very interesting! My pet peeve is glare and LEDS produce an ungodly amount of glare and I absolutely hated them in car headlights. I've never heard of anyone irritated by hz that high before. The more you know. Thanks for clarifying.
Glare? That's not a physical property of LED light but an effect of overly bright headlights enabled by LED and laser technology.
Except my eyes do a kind of color aberration where I see different wavelengths in slightly different spots when squinting, and the peak of blue that most white LEDs' spectra have makes for a clearly visible fringe. I wouldn't really call that "glare" though.
