G'day,

When creating light bulb plasma globes, you always should choose the
higher wattage bulbs (~60W +) as they are filled with nitrogen(?).  The
lower wattage bulbs are supposedly only a vacuum, and I did not get any
success with these.  If you connect a light bulb to a NST unmodified (I
used a 12/30), and connect one HV terminal to the filament, and the
other one is connected to the outside of the globe, you will get a VERY
intense plasma, which will heat up the bulb rapidly.  So the below
comment would make sense.

Is the light bulb interior a vacuum or does it contain a non oxidizing
gas
like nitrogen?  Seems like if it contained a gas, this would help in
conduction of heat to the glass container.
