I have a flickering LED downlight in the kitchen. It's not the PSU, I've
run it from a bench supply and it still flickers. It has a three
position switch to change the colour temperature and the LED comprises a
17x20mm white board with two multiple chip LEDS, a central warm white and
an outer ring of daylight. Te switch selects either or both. Only the
warm white flickers, but this is the one we use. It's not the switch, I
tried swapping the wires and there's no electronics in there.

This is a 30V 10W device, I could easily fix it if I could source the LED
module, but I can's find a source - any ideas?

I don't want to replace the whole unit as there are others which it
matches and I don't think the same model is available.

I have found that LEDS like to flicker

None of my Philips Hues do.

Any or all of my kitchen ones will interact with each other even though
they are on different dimmers.

None of my Philips Hues do.

When I had a desk light plugged into my bench and I was using a belt
sander on an adjacent socket the LED would sometimes flicker when the belt
sander was switched off.

None of my Philips Hues do.

The LEDS in my office here sometimes flicker on voltage surges too

None of my Philips Hues do.

Perhaps an RF choke in series?

LED technology is still work in progress

Not with the best of them.
