It is a "catch 22". If you buy led's that do not have a "buck" voltage controller RFI is lower. However, they burn out. damik.
Currently the "best lumen for the amp-hour" is tubular fluorescent. Coincidentally they are also the "best bang for the buck". I can't speak to RFI and such fixtures.
I don't know about the RFI but I do have concerns about putting a compact fluorescent in my travel trailer. I am concerned with the vibration and shock from traveling causing a failure and the bulb breaking. Every last one of these things contains mercury. Not very much but enough for the manufacturers to recommend that you evacuate the house/RV and use haz-mat procedures to find and clean up the debris. As I understand it, you don't need very much exposure to mercury to cause significant problems.
This is not something that I am interested in!
