How did you survive office buildings, airports, department stores etc. prior to leds? I am by no means sensitive to flicker, but fluorescent tubes which were used in pretty much every office building/large department store, before leds became common, used to flicker like crazy in comparison. And there was always at least one which was broken and flickered on and off very slowly (including the characteristic sound).

Strangely tho there is something about PWM flicker, especially the kind that is deep cycle (basically 100% on then 100% off) that are super bad for me. I can look at an old CRT fine because it’s not completely on and off as it does it’s scanlines. But PWM is like flicking a light switch rapidly and it gives me the worst headaches.
