The verdict
A single color A19 bulb. Its white light is good (CRI 89, Rf 90), it dims down to 18 lm, its warmest white is 2708K, and flicker risk is high.
The flicker is the problem. At full brightness it measured 20% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
