Again as with other topics, my experience is only one mans experience,
making it anecdotal but I have, or rather had CFLs in all the house
lights. I did no checking other than my normal 160 through 440
operation. I heard no interference, or detected any increase in noise
floors. Going to the screw in LED replacements was the same. I made no
special search for specific manufacturers, or brands.
The only interference I've found was from a computer to my HT setting
"on" the computer breaking the squelch with an S2 signal (hash). A foot
away and it could not be heard even with the squelch open.

Hello Group,
A quick post regarding my RFI experience with CFL bulbs.
I recently bought 3 brands of CFL bulbs at the local big-box DIY store for a
nightstand lamp.
I placed my SW portable on the nightstand (about 1.5 feet from bulb) and
listened on 454 KHz, 4, 7, 14, and 21 MHz for RFI.
I heard significant RFI from the Philips EnergySaver Silicone Coating 14w =60w
featuring TuffGuard protection, soft white, shatter resistant, 790 lumens, 2
pack.
I heard significant RFI from the Cree 4Flow, 60w, 2700K, soft white, dimmable,
815 lumens, single pack.
I heard nil RFI from the GE energy smart, Bright from the Start, 60w uses 15w,
800 lumens, soft white, 2 pack.
Thus, I recommend the GE energy smart, Bright from the Start CFL bulb for RFI
sensitive applications. As always, YMMV.
Hope this helps.
