VOLTARC UV-LUX GPH357T5L-S400 Low Pressure Mercury Germicidal Lamp
Lampe germicide à vapeur de mercure basse pression
Entkeimungslampe, Niederdruck-Quecksilberdampf-Lampe

The peak output of this lamp is at 254 nm (UV-C) for use in water purification and sterilization systems.

GPH lamps incorporate a switch that initially connects a combination filament–cathode at each end of the lamp to preheat them and requires four electrical connections. This allows the use of compact ballasts that are relatively inexpensive. When the arc is struck the filaments are disconnected. There is a slight delay before the lamps start.
