Hi mate, I've merged your topics, I think it makes more sense to have it under lighting than beginner Qs, hope you don't mind. 😊
As for the noise, is it like an electric buzzing sound (as opposed physical from the fan bearings or whatever)?
Sometimes you get that from the type of dimming (PWM) that LEDs use. Not sure if there's a fix to be honest, other than replacing the unit.
