I have a house / shack full of CFL lamps, with absolutely no noise from them. Our homes can be infested with noise generators, from touch-lamps to washer / drier units, but CFL's are most likely -not- sources. In some circles CFL's and their supposed problems have risen to urban legend level. (;-) 73! Ken - K0PP http://timyurl.com/7lm3m5
