This video is unavailable. vapor lamp is a high intensity discharge lamp. High Pressure Mercury vapor lamps were all over around Athens even before the author was born and some have still survived. The mercury lamp tube is filled with inorganic mercury and a small amount of Ar and Xe deactivated gas. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. With theircool-whitelight,theywere,untilthe1970softhelastcentury,extensivelyusedinroadlighting, The photo below High pressure mercury vapour lamp with elliptical bulb, coated, base E27. It can take several minutes As the mercury vapor in the lamp further increases, the intensity of the visible spectrum line gradually increases. The pressure inside the cold (room temperature) mercury lamp is as low as the atmospheric pressure. He would create an arc through a metal, directly from it's own arc. A basic mercury HP lamp will emit energy in both these ranges, but its strongest emission is in the short wavelengths. Mercury vapor lamps were the forerunners to fluorescent lamps. Since high-pressure sodium lamps have mercury and sodium inside it needs to utilize a high-voltage pulse to ignite the lamp, which the ignitor provides.
