[CQ-Contest] QRN from CFL's ?

We've been replacing every lamp in the house that gets more than 
occasional use with compact fluorescent lights and I notice no 
change in the general noise level - in spite of a wire antenna 
that runs directly over the roof and an R5 vertical mounted to 
the eves in about the middle of the house. 

The most recent additions have been 120 watt (equivalent) reflector 
floods.  All of the table and desk lamps are now 60 and 100 watt 
equivalent lamps.  I've been using the generic (low cost) lamps 
from Home Depot, etc. and not concentrating on "brand" names like 
Phillips, etc.
