I am sensitive to low refresh rates - back in the crt days I would visibly notice low refresh monitors and it would give me headaches. Some (low cost?) led bulbs give me the same effect- I can see the rapid flicker. Some hotel rooms are notorious for this.

I have led bulbs everywhere (new build, recessed lights). Thankfully they don’t have the flicker effect I’ve seen on other bulbs. And I’ve found that I actually prefer the more “daylight” bulbs in certain areas such as kitchens. The cans do have adjustable color temperature (a physical switch) so it’s not too bad if I decide I’d like a warmer light down the road.
