making fluorescent lights for houses

Fluorescent lamps work by creating a low-pressure mercury vapor plasma; electrons in the plasma produce ultraviolet light that excites a phosphor coating to emit visible light. Observing aurora or solar flares is studying natural plasma, and making telescopes is not a use of plasma.
