Same 23 watt CFL used in each case for current trace.

Normal AC supply versus pure sine wave supply.

Voltage trace = 100 V per div

Current trace =120 mA per div



How did you get the clean AC, Phil? I'm assuming that the blip on the
voltage waveform where the CFL fires is because the supply isn't of a low
enough impedance, so is it from the output of an amplifier, stepped up
through a step-up transformer?

Your mains supply looks rubbish! Are you on the end of a long feed?

Nice pics, by the way.
