LED ceiling light dimmable with existing switch

[CopperBolt]

I’m looking for either a flush flat round style light, about 30cm across
Or 3 led crossed over strips style lamp, something not too deep overall and that is dimmable with my rotary dimmer switch already in place.
About £50.

Googling either gives me ones which have 3 presets for brightness or aren’t dimmable.
There must be something out there though.
Black or brushed nickel/chrome finish ideally.

Thanks all.
