You want something that creates an abomination of a waveform in the mains? Here, use of fluorescent lights is almost universal. Not just CFL's, those are relatively quiet. Also 2' tubes, 4' tubes, and those 'bent' lamps are used extensively in kitchen and bedroom lights. Millions of fluorescent lamps all operating at the same time creates RFI to the tune of S7 to 20dB over S9, depending upon time of day and meter band.
