You misunderstood. 2 out of 4 light that I have is having issues.
Sometimes they cannot be turn on. Sometimes they can be turn on but turns off by itself after a few seconds or after 30 minutes. Totally unpredictable and unreliable.
No dimmer, no deformation of docker, no issues with wires because when I put the other lights that I have at their positions, there was no problem at all.
The 2 problematic lights are:
Yeelight Moon model: YLXD05YL

Yeelight Ceiling Light model: YLXD01YL
