if you want to measure true wattage, the best way is to heat something and
measure the heat - it seems to me that a KW lamp in series with the low
voltage side of the 60 HZ transformer would be a good and inexpensive device -
then measure the brightness of the lamp - that will have a (nonlinear but well
known) relationship to power, and can be part of your ballast anyway. If
there is too much drop, use a lower voltage bulb - a car headlamp bulb with
both fillaments in series is a 30 amp device - and an incadescent bulb is
approx constant current within it's normal operating voltage range (because as
you apply more volts, the filament resistance goes up due to increasing heat.

A brief comment on this idea from John....

I think the comparison can only truly be made if k is the same for
each system. A true power meter which takes the phase angles into
account should do the trick shouldn't it?
