Gary,

I think a photo sensor of some type would be better suited to this.  The
thermocouple would work, but it will not be able to react to changes very
quickly, like adjusting the voltage on the variac.

This makes me think, do we even care about what the bulbs are doing? Why not
just measure the actual power coming from the wall? The power coming from
the wall is proportional to the power going out of the NST.  Any increase on
the output side will show up on the input side.  The Kill-a-watt would be
perfect for this task, and provides those quantitative measurements you
seek.
