The verdict
A single color B39 bulb. Its white light is good (CRI 90, Rf 89), it dims down to 8.8 lm, its warmest white is 2692K, and flicker risk is high.
The flicker is the problem. At full brightness it measured 18% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
