As an avid shortwave listener and .....
...an amateur radio operator who frequently operates on high frequency (3-30 MHz), I won't use CFLs because of the tremendous electromagnetic interference they cause. I also turn off all dimmer switches in my house also.
I have subsituted LED based lamps for incandescents in some cases. They don't provide that much light, however, power consumption is very low and as long as the internal supply is not a switching power supply, no EMI (electromagnetic interference) is generated.
My wealthy neighbors over 100 yards away from my house use high pressure mercury lamps for "security" around their house ... UGH. I watch the noise floor on my receivers go up by at least 20 dB when those lights go on because of the ballasts in the lamps.
