Hi.
When I turn on my Yeelight ceiling lights a really annoying high pitch sound is emitted by it. I noticed it before, but now that I installed it in my bathroom which reflects the sound and it drives me crazy…
I am in the Netherlands. 230V.
Can this be fixed?
Hello!
Just want to add that i have the same problem with the ceiling lights. Installed today in my living room and its unusable.
The sound is scaling with brightness. In Moon mode it sounds like a mosquito flying around and in Sun mode its like several hornets in the room.
Btw.: Germany 230V.
Same question: Can it be fixed or broken unit?
Hi, I’d like to know that as well 
Have you somehow fixed the problem?
Hey guys!
First of all it is really sad that they sold us thèse bulbs. As far as i am concerned i am disappointed that i bought such shit things like thèse yeelight RGB bulbs.
To answer your questions: Although I am not a développer at Milights or anything like that I am just a Guy who bought 5 bulbs for my home and realized how awfully stupid i was. No, it probably Can not bé fixed. LED lights Can be dimmed down with two possible ways. First is thé cheapest way which i dont even know thé name. It does dim LED lights and it has a high pitch noise when used. Also it Can change the colour of thé plasma.
The second is analog which is a usual résistance dimmer. It Can not bé used with any kind of LED and it is a little bit more expensive. Although it doesnt have a noise.
So in nutshell we Can not do anything about it because they screwed us over and it has this noise. That’s it.
Btw I have a dégrée as a lighting technician. I work in thé film industry where you Can Guess which type of dimmers we prefer.
Good day to you all!
