We have no dimmers except the on/off dimmers called wall switches. ;-)
Re: LED's. I have three CREE LED bulbs in my ham shack std ceiling light fixture with no RFI. My wife is substituting out incandescent and bad CFL for LED's she found at Home Depot (not CREE - I think they are GE). They also directly install in std light fixtures. They are cylindrical in shape. Also are not bothering the radios.
I have a desk fluorescent and garage has 30w tubes which do not seem to cause RFI. The switching PS for our new Direct-TV satellite receiver throws out bad RFI on 2m. Fortunately, I am usually in front of the TV most of the time it is on. I will have to try clamp-on ferrites at some point.
I have a friend that acquired LED's from Costco and he is plagued with RFI from them (no idea of brand or model). Definitely caveat emptor on converting to LED lighting if you are a ham.

How much is a good old fashioned light switch at the big three, $1.50, two buck if you want a matching switch plate. When we bought our house I replaced six dimmers. Didn't hear a peep from "she who must be obeyed". I have about that many CFL's to swap out for LED's. The garage fluorescents will be a different story. They get to stay as long as they stay radio quiet. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
