Govee H601C 6" downlight full color smart bulb

The verdict

A full color 6" downlight bulb. Its white light is dull (CRI 78, Rf 83), it dims down to 47 lm, its warmest white is 2685K, and flicker risk is high.

The flicker is the problem. At full brightness it measured 91% percent flicker. I would keep it out of reading lamps, desks and rooms where anyone is flicker sensitive.
