[RFI] Low RFI 60w CFL bulb

[Chris L. Parker]

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.
