Have you done any real testing for RFI NOISE from your controller boards. My experience with LED VOLTAGE REGULATORs is they are prone to produce high Radio Frequency Interference and in my case interferred with my OTA HDTV reception, VHF WX RADIO Interference, and really big time interference to my ham Radio VHF operations...
My way out was to use LED BOARDS that did not include VOLTAGE REGULATORs like the $4.95 LED BOARDS from EBAY CHINA...
Just asking....

I don't have much experience in that area. I did follow the manufacturer's reference design as best I could which they claim minimizes RFI/EMI, including good quality high frequency bypass capacitors on the input and output. The high frequency "switch node" on my circuit board is wrapped by a ground plane, and I'm using a RF shielded inductor.
As sloppy as some of the LED circuit boards I've seen are, I believe your claim of interference. I understand they want to keep costs down, but doesn't the engineer that designed the board have any pride in his craft, I mean, come on!
