High pitch noise Ceiling light


Hi Yeelight. I’bought the Ceiling light 320 and it’s in my bedroom. I can hear silent high pitch sound when it is off from my bed. Also different sound when it is on with low intensity. Since it’s in my bedroom it’s quite annoying. Is it defect or characteristics? Do 450 or 480 have this problem too? I might wanna exchange it :frowning:


Do you have an adjustable light switch or just an on\off switch?


What do u mean? I am using enclosed bluetooth remote control. The light is always under power. My wall switch is standard on off, what has it common to high pitch sound of the light itself? I know that the lamp is under power because conected to wifi even when off, but I want to know if others have this sound too.
