Interesting. Are you trying to reduce rf noise because it interferes with something? How do you measure the RF noise? I have several high quality Bluetooth devices and keep getting occasionally spotty service. I'm thinking it is rf interference.
I listen to short wave radio, and my radio itself is an excellent RFI detector. I just wandered around the house with it holding it up to things until I identified the problem. The only things really emitting lots of RF were LED and CFI bulbs, and a couple cheap power supplies for Netgear info-appliances.
There are LED bulb requirements in California, and people have mocked them, but as I understand it they are supposed to help address this issue, as well as color quality and audible noise issues.
In other words, California says no to cheap shitty bulbs.
I’ve heard garage door openers can be very sensitive.
Incandescents make the plastic go yellow, so people have searched long and hard for a light that doesn’t heat up but still lets you open and close your door.
