Hello Michael,

I built one of these a few months ago using the exact same
circuit you describe below.  Its a little neat gem, fun to
experiement with.

Same here,  for a time, I was certain not to run it too long
since it was in a small plastic box.  I have .750" heat
sinks on it.  Left it on by accident for about 15 mintutes
once and everyting is still fine.  I plan to add a small CPU
fan to it if I use it much more.

I have experimented with several lights to build a plasma
globe  I thing there might be too much current for a regular
light bulb.  I have cracked the glass more than one.  So
just be careful.

I haven't noticed.

There's my nickles worth.
