High flickerAmazon Basics 11aSB-A800ST-Q1-WZN A19 tunable white smart bulb
The verdict
A tunable white A19 bulb. Its white light is excellent (CRI 92, Rf 91), it dims down to 15 lm, its warmest white is 2124K, and flicker risk is high.
The flicker is the problem. At full brightness it measured 38% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
