Mercury lamps

Mercury vapor lamps (HQL) are often used as light sources for street and factory lighting because of the low investment costs. They need a ballast but not an igniter. Because of their low efficiency, mercury vapor lamps consume much more electrical energy than metal halide lamps or high-pressure sodium lamps for example to achieve a certain quantity of light.
