CFLs lead in phase due to an either real or effective capacitor in the
ballast, as I understand it. Therefore, you want to include an
inductor in the circuit to bring in back in phase and the power factor
back up to 1. Most CFLs produced today have a 0.5-0.6 PF.
Keith, you're an EE, aren't you? You should know power factors and
phasors better than I do. Physicists are dirty hacks compared to EEs
when talking about this stuff. :) Most of my info comes from an EE who
works in designing lighting systems.
