A plasma is by definition a mix of free electrons and charged atoms.  Some of the electrons have to be removed from atoms to give a plasma its electrically conducting properties.

Sorry your revised question is not really understandable try to rephrase it and give some more detail.

People generally do. Do you think saying that helped?

Anyway, they don't give much light because they are not fed with much power. They are not designed to give much light.

It is still producing a plasma, but it looks like most of the discharge is coming from certain "hot spots" on the central electrode.

Could some oxygen have entered the globe, and oxidized part of the central electrode?
The plasma would then preferentially pass through certain weaker points in the oxide layer.

That looks more like a disco light with a bulb in it rather than a plasma ball.    The light you see on your camera is because the camera is much more sensitive to light than our eyes. The reason it is not super bright is because of dispersion to the volume of space, it disperses at the speed of light.
