Bart -

When you make the test I suggest that you keep the input wattage just below
the point where streamers would occur. Raise the variac voltage to say three
different input wattages below the sparking point and record the lamp
wattages. This would give us three points on a curve of input vs output
watts. This would also give us three efficiencies which should be close
together. We will then have a start for discussions regarding the test.

Thank you and good luck with your tests.

Agree. The thermogun will read the surface temp of the bulb. Air currents
won't be a problem. Their
easy to calibrate as well (boiling water as temp source). I may have one
floating around at work. I
would need to measure my existing coil. John, after the reading the test
procedure I now "get" what
your doing here with the bulb measurment. This is a standard form of
comparison measurement. I'll use
volt/amp concentric readings. I've got variacs and all that jazz so I don't
see anything upfront that
would hold prevent me from making the measurement.
