Mercury vapor ballasts are usually rated by an ANSI code. The most common ANSI codes for mercury vapor ballasts are: H46, H43, H36, H42, H39, H37, H33, H36. Standard mercury vapors are known for their grayish white color and long life of operation.
Ballasts for lighting applications are simply transformers to provide the right voltage and current mix to the gases inside the light bulb. They are commonly used in commercial applications for street lighting, wall packs and floodlights, fluorescent strip lights and recessed troffers.
