Anyone Try These For Triac Dimmer RFI?

[W2VW]

Avoiding using dimmers around the house due to the amount of crud the lamp power feeds are radiating.

Garden variety triac dimmers and incandescent bulb loads from 60 to 600 watts.

One online solution suggests these:

They are fairly pricey if they are just a coil on a core.

I'd like something that would fit within existing wall switch J-boxes which is most likely too much to ask.

Anybody work with these?

Dave,

No, I have not worked with these.

My guess is that you can do a better job urself.
For starters, shielded wire going TO the coil thingie would be my first reaction. Assuming it is external.
Maybe some clip-on ferrites would do well, that and pulling the front plate of the dimmer
and coating that with conductive paint, grounding that too...

Common mode "Corcom" boxes might be best/better - but where to fit them?

Royal PIA, imo.

The chokes keep the buzzing RF noises from being conducted far from the dimmer so that the 'antenna' is short. There is no need to pay a lot of money for that, as a toroid with a bunch of turns works. Picture shows one on a dual 20A dimmer but the idea is the same, that the coil is close to the device.
