    I have a dimmable LED that begins to buzz after about 30 minutes of being on, is this simply because it has warmed up or something wrong?

    Can anyone recommend a solution or a good quality bulb that doesn't buzz?

    Which LED lamp and dimmer are you using?

    does it buzz on full or only when its being dimmed, if when its dimmed does it stop when you turn it up to full

    Only when dimmed and yes turning it up to full stops the buzz

    I'm not really a fan of Luceco LEDs. They aren't very reliable.

    Try something like a Philips or Megaman lamp.

    Thanks I'll do that. That fact it's quiet to begin with suggests the LED is the culprit

    Yes, if kept at the same dimming setting something inside the lamp is getting hot (possibly a coil) and it starts to buzz.

    Where are you getting the neutral from for your switch?

    It comes down from the ceiling rose back to the switch.

    So you have a live, a switched live, a neutral and an earth to the switch?

    Yes I do. I was surprised the neutral was there, my house is a relatively new build.
