High pressure sodium lamp long run (4Y), tubular bulb clear, base E40. Operation with ballast and ignitor. Medium-pressure lamps draw a much greater current than low-pressure lamps, leading to a rapid rise in the mercury vapor pressure. This gives a typical diffuse medium-pressure UV spectrum (see Figure 3).

High Pressure Sodium Vapour Lamps with a polycrystalline translucent aluminum oxide discharge tube enclosed in an ovoid or tubular outer glass envelope. The mercury vapor lamp is a negative resistance device. This means its resistance decreases as the current through the tube increases. So if the lamp is connected directly to a constant-voltage source like the power lines, the current through it will increase until it destroys itself. Therefore it requires a ballast to limit the current through it. (Working avi) Mr.Kantoli S.B. BMP
