They are also called "Rough Service" bulbs. For years I thought that that was "rough surface" from the bulb's coating. No RFI from them AFAICT. At home I use a remote-controlled light dimmer for a table lamp. It's a double threat - the remote Part 15 and the dimmer electronics. After ruining one with an LED I RTFM that said "incandescent only". I then found a similar dimmer at a specialty lighting store that was certified for LEDs. It was also necessary to get a dimmable LED - not all are. I tried it out at the store to make sure that it would work together. The upshot is that I cannot detect any RFI even though the lamp is in the next room. Of course, with the high HF noise level here, it may just be masked. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ 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]
