natural - lightening, the auroraman made - neon and florescent lights
by making light
In a cobweb, near florescent/bright lights, and on your food!
A florescent tube is still a mercury vapour device and needs the mercury to vaporise to have the tube conduct to emit visible light.
For PLASMA tv and lights
Yes. The cells in a plasma TV contain a mixture of gases that are typically found in neon lights. When a current is passed through the cell, it ionizes the gas, turning it into a partially ionized plasma. This plasma differs from the plasma found in the Sun, stars, and interplanetary, which is typically fully ionized, and hotter.
A Plasma must contain many ions and electrons.
Many things contain plasma mostly things in the sky.

The sun, arc welding, "black lights" (looking fro fluorescence). [inside florescent lights - but its blocked by the surface of the bulbs.)

it depend on how it starts most of them do have plasma
