Neon bulbs work on the principle of voltage-induced ionization, creating a visible glowing plasma. If the applied voltage is high enough, around 60 to 80 V, electrons get knocked off the neutral ...
the introduction of LED lamps is starting to gain ground with its ability to help save fuel costs, and the recent introduction of plasma bulbs offers a unqiue - but still in its infancy - option.
