Scott -
I put the screw in type in the ceiling fixture in the shack, and the 
adjacent kitchen and garage have tube fixtures. I've noticed no RFI. The 
screw-ins (2x60 watt)are dimmer than I'd like, so I'll go to higher 
power next time. They're not lasting 4-7 years though. More like 9 
months. I can't tell any difference in my electric bill either. I think 
it would be in the cents rather than dollar range.
