I had the same problem with 450 Ceiling Light, but I solved it.
The main cause of the noise was the brown capacitor marked with a red circle.
The part was in contact with the blue part marked with a yellow circle, which amplified the noise.
Tilt the brown capacitor in the opposite direction so that the two parts are not in contact.
Symptoms have been alleviated to the point that it does not hinder the use now.
