Mercury vapor lights operate at an internal pressure of around one atmosphere and require special fixtures, as well as an electrical ballast. They also require a warm-up period of four to seven minutes to reach full light output. Mercury vapor lamps are becoming obsolete due to the higher efficiency and better … Meer weergeven A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger Meer weergeven The mercury in the tube is a liquid at normal temperatures. It needs to be vaporized and ionized before the lamp can produce its … Meer weergeven Low-pressure mercury-vapor lamps usually have a quartz bulb in order to allow the transmission of short wavelength light.
