I've had one of those replacement fluorescents on 24/7 for years and
never a peep. It's in the basement directly under my shack. I think
it's a 15 watt with the light of a 40 or 50 watt regular bulb.
I do have a couple of shop lights, (4 foot) which are terrible noise
makers until I changed the tubes. My next door neighbor has one also
and when it's on it puts out S-9 noise. I bought a MFJ 1026 which
takes it out completely. The NB does the job too but distorts the
audio of the station I'm trying to copy. The dimmer lights are
awful, I had one and I not only received noise from it I caused it to
turn on when transmitting. I partly cured it with a RF choke and a
resistor, but not completely. It's unplugged and not in use anymore.
