Of course, flourescent bulbs create RFI.

They are still relatively harmless compared to other sources though -
move away some 2 meters or so, and their effect is largely gone
(certainly when using a magnetic antenna). My parents' plasma TV
radiates quite heavily, not like the previous CRT would have been much
better - enough to make 20m unusable in any case, and that in quite a
distance. My network equipment (particularly switches) isn't that
well-behaved either, while the computer itself doesn't emit that much
actually. Thankfully dimmers have never been an issue.

BTW, we haven't been using large incandescent lightbulbs for years,
except for door lighting where they still make sense as no warmup is
needed and operating time is generally small. Otherwise a 20 watt
compact fluorescent gives a decent brightness here. Oh, and flicker
these things do not, but my cheapo desk lamp with a 20 watt conventional
fluorescent and apparently a primitive starter does (which annoys both
me and the camera's autofocus). As someone with lousy vision I'm usually
not opposed to a bit more light, which with conventional lightbulbs
could quickly mean wasting hundreds of watts just on lighting, and
that's a bit much. (Even my computer barely tops 100W, monitor
included.)

Something that does not seem to be present yet are compact fluorescents
with high CRI (color rending index), meaning a more uniform coverage of
the visible spectrum. Quite a pity.
