I changed over to LED last year with mostly great results EXCEPT for nav station LED with lots of RFI messing up radio reception. A great blog that I follow from a sistership in the South Pacific (cruise of the ladybug) mentioned Alpenglow. I just installed the dimming fixture and joy the RF is gone. Their website says many dimming fixtures use off/on circuitry to lower the light level but they use linear circuitry, all I know is that it works.
