Robert,

Well.. Yes and no. If you are near the limit of the service capacity for
the circuit you're using, adding PFC's will allow you to increase the
effective power being used by your system significantly (30 - 40%)
without popping the mains breaker. Also, a large (10's or 100's of uF)
cap sitting across the line is an excellent pulse snarfer for helping to
absorb high frequency/high amplitude nasties that can arise from
kickbacks and voltage transients stemming from the inductive ballast.
This will work for either neons or pole-pig applications. Voltage rating
of the caps sould be at least 3-4X the RMS voltage on the line.

PFC'in in Illinois...
