Mercury vapor lamps have mercury in them, which has a clear arc tube, which you can see the electrodes and the starting electrode. The arc tube itself is made out of quarts. Mercury vapor lamps need to be on a mercury vapor ballast/transformer, in ANSI of "H" with the number next to it, like for example: "H39" means 175 watt mercury vapor.
