just because somebody decides to geek out about LED bulbs, does't mean all those stats that are theoretically measurable actually make a difference. the 4-for-$10 A19 LED bulbs from amazon or ikea are flicker free to my eyes. i've bought some fancy bulbs with big metal heatsink bases, supposed "high CRI" ratings, equivalently high price tags. to my eyes, i can't see the difference. the super-cheap bulbs from one of those amazon marketplace sellers with a randomly generated name are flickery, but just going up to anything other than the absolute bare minimum of quality is good enough. "what the peasants get to use" is because that's actually probably good enough for what us peasants need. if you want to geek out about super high-end LEDs, you're not going to find that in consumer-grade products and that's probably fine.

> are flicker free to my eyes Very rarely will bulbs visibly flicker in my experience. What happens instead is after several hours I'll start to get headaches and feel fatigue without knowing exactly where it's coming from. Since I replaced my Hue bulbs (which flicker, and I proved it by just using my smartphone camera even) I've felt so much better at home

  I second the A19 and other bulbs from Ikea. I live right next to an Ikea and it turns out their bulbs are pretty good. Even the housing feels better than Phillips or others. I used to have an expensive Phillips light alarm and it flickered like no other. Especially if you lower the dimming you'll tend to see more flickering or just notice an "ick" feeling with crappier bulbs.

  >which flicker, and I proved it by just using my smartphone camera even all bulbs have some flicker, and the fact that it resonates with your phone screen's refresh rate or your camera sensor's sample rate doesn't really mean anything.

    No, if you spend money on a good LED and get a photodiode hooked up to an oscilloscope, you can quantify the flicker. The good LEDs will have absolutely zero.
