I believe the reason the red and blue leds were so hollow on this bulb was because only the square LEDs were trying to carry those light waves.

The outer circle's silk screen says c1...c10 and w1...w10 , which I believe is both for whites (cold white 1 ... cold white 10, and warm white 1 .... warm white 10).

I'm looking ways to salvage and make us of that #ESP8685 module.

The light PCB looks okay, so I'll save it as a spare or will tinker over it.

There is ESP8685 (C05M ?) MCU inside of the smart bulb, and you can see the swollen capacitor at right side below it.
