High flickerDiscontinuedIKEA Tradfri 204.391.94 A19 full color smart bulb
The verdict
A full color A19 bulb, now discontinued. Its white light is fair (CRI 84, Rf 88), it dims down to 10 lm, its warmest white is 1850K, and flicker risk is high.
The flicker is the problem. At full brightness it measured 65% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
