I hate those light bulbs. They blink at I think 120hz? Idk maybe that saves energy as half the time the light isn’t on. And maybe most people can’t tell.
As an object moves in sunlight it looks smooth to your eyes, but under a blinking light you only see the motion during moments that get lit up. This is much more obvious for faster motion.
I’m not 100% certain but I think this sort of lighting triggers bad headaches for me. I get bad headaches some times, and I’ve always been pretty sure the lighting was why but I’ve only recently started confirming with my phone that all those places where I get headaches use blinking overhead lights for the entire room. More and more places around me have adopted it and it’s awful. I have tons of clips in my phone now of random locations in slow motion, many of which have these lights. I can’t walk through a store that’s using them for very long.

It is because the LED drive/power supply electronics is too cheap to have enough capacitance to maintain the LED powered while the alternating voltage is crossing zero. I used to get headache from flickering CFL lights in store when I was a kid. Those days only the worst LEDs make me uncomfortable. Some LED bulb will flicker with a really sharp cutoff, they are the worst. Many will flicker, but not down to zero light. This does make a difference.
