What is this Mijia bulb?

Yeelight LED Bulb (Color)
#1

Hi Guys, Looking to instal the latest & greatest RGB bulbs in my house just now, I presumed the latest model was the 1s.
But now I have came across this very very strange Mijia branded bulb that goes higher, to 900 lumens.
Does anyone have info on this? Very very odd.
Thanks
