Of course
there will be  alternatives to flourescent lights, but
in general, whatever is the cheapest,  is what the
average consumer will buy. What type of noise filter
will we  have to build next ???

Hi Andy,
I don't seem to have any problems at all using the small fluorescent bulbs  
in my home. Even when listening to LF/VLF the small fluorescent lamps are very  
quiet. Of course this is using an outdoor active whip antenna, the receiver 
is  grounded and I use an isolation transformer to power the radio for good 
measure.  The only time the small fluorescent lamps cause any trouble is if I  
place something like a small portable AM radio with ferrite rod antenna within  
2-3 feet of the lamp then I can hear a broad 'sizzling' sound in the radio. I  
don't think those bulbs radiate anything more than a few feet.
 
The more common solid-state lamp dimmers generate far more noise than I  ever 
noticed from the fluorescent lamps. I have to turn the light dimmers OFF to  
get any useful listening on LF/VLF at the home QTH.
