Hi Ron -- I'm surprised you see that with 110v.  Might want to chase around
with both AC and DC meter and check your grounds.  Anything at all that
moves the LED panel ground positive to the thermocouple output by more than
a millivolt or two will light the light.  As you've seen, any significant
DC load on that circuit will do it.

Whatever's happening on the AC side, I'd expect that the LED is actually
flickering at line frequency when it's lit for that reason.  You can check
by flicking your eyes from side to side while looking at the LED, (or by
putting an AC meter on the LED -- most digital AC meters reject DC).
