Once the old ballast type have started up into a good bulb you will
probably not hear much noise from a fluorescent but the newer high

How about the new Xenon (flourescent-type) fixtures - we're getting ready to
put these under cabinets in a new kitchen. Anybody have experience with
interference from them?

I would need more information from you on the model. I would get a
report on the fixture before I bought it. Basically it comes down to how
the current for the bulb is regulated in the amount of EMI generated.
Some RFI is generated by the bulb plasma when conditions are not good
for the bulb. You might want to just buy one unit and test it with a
radio. The problem is that things may change as the fixture ages. The
unit unit might not be a problem until later in its life.
