No different than going to Audio Shop and you see 4" 1,000 watt
speakers. There is a BIG difference between RMS Power and Peek Power,
but people only things with bigger numbers written on them.

typically fairly small, often current is leading by a few degrees.
the main reason for the low power factor (if you must analyse them in
the frequency domain), is all the harmonics.
