NOTICE!!! Manufacturer has started using unsupported non-ESP8266 chips recently and this device might not be compatible anymore. Check seller descriptions or contact them before buying!
If your bulb does not match the pictures below, check if you have the newer v3 version of the bulb.
As of October 2020,
tuya-convert no longer works on this bulb due to a manufacturer firmware update.
Opened up the bulb to see if serial flashing was an option, but could not solder wires without destroying the fixture.
If you find a way to serial flash without removing the PCB board, please update this page.
Note there are two diffusers. The outer one should pop off after a few rotations, but the inner one may be glued on. A flat-head screwdriver will help remove the inner one.
