Pressure doesn't really matter. The ionized gas a lightning bolt passes 
through is at quite a high pressure for a short period of time. And the 
sun is just a big ball of plasma with portions at an extremely high 
pressure.

Different temperatures and voltage potentials. The ball contains a 
mixture of gasses, some only ionize and glow at the central electrode.
