too bad the CREE stuff tested poorly, i believe it is even American made ..
Maybe they got some of their RF devices in the bulbs by mistake??.

Subject: [RFI] Low RFI 60w CFL bulb
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.
