[RFI] POE home lighting experiences?

[John Langdon]

I was more worried about PWM controllers and harmonics, even with a conventional power supply. I guess I'll have to demand to listen to an installation to see if it generates RFI or not.

A decade plus or so ago in a house we no longer live in, we had it installed.  I requested use of ONLY a "real transformer".  What did the installer use?  An "electronic transformer".  This is nothing but yet another SMPS with no decoupling what-so-ever.  It killed all of HF, the AM BCB, and upwards of 2-Meters.  Just say NO........

Long story, but I forced them to remove the "electronic transformer" and install a real hunk of iron and copper.  Of course, the RFI ceased.
