Unlike sodium lamps there is also radiation in voltages are also nominal. For mercury and metal halide the ultra violet region. This invisible radiation can be lamps the lamp voltage remains about the same through converted into useful visible light by coating the inside of life. However because of manufacturing tolerances there the outer lamp envelope with a phosphor material. will be a variation for individual lamps.
