Distribution and sale of discharge lamps with neon technology, metal halide and sodium vapor. Fluorescent discharge lamps, metal halides and sodium vapors use different internal elements, but they share the same as for the ignition phase, in fact to turn on they need an electric discharge of some low current Kv. All the discharge lamps need to turn on an electronic or electromechanical ballast (less efficient), this will generate the necessary discharge when the source is turned on. Neon gases are inserted in fluorescent neon lamps, in metal halides, iodide gas in this case, and inert lamps mixed with sodium are placed in sodium lamps. To achieve maximum brightness, these bulbs require a heating time of> 20 seconds, which is why they are not suitable for installation in places where several ignition cycles are required over a short period of time.
