I use incandescents at my home because the alternatives are very RF-noisy. GE's incandescents are (were?) among the worst for life. Thankfully there are American companies making quality incandescents right here at home now.

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.

LED bulbs with FCC part 15 certification should be RF-quiet.[1] If we're going to have anti-China tariffs, a useful thing to do would be to require FCC and UL approval. Power supplies would cost a little more but would not catch fire, and few things would blither all over the RF spectrum.

  exactly ... chinese electronics are cheap but of very low quality and yet very RF noisy ... I have burned through several such power adapters ... total junk

In the winter in cold climates, incandescents are fine anyway. They're 100% efficient because the "waste" heat is still being utilized, particularly if the building is heated electrically anyway.
