High flickerDiscontinuedIKEA Tradfri 205.187.37 A19 tunable white smart bulb
The verdict
A tunable white A19 bulb, now discontinued. Its white light is good (CRI 88, Rf 90), it dims down to 26 lm, its warmest white is 2254K, and flicker risk is high.
The flicker is the problem. At full brightness it measured 26% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
