There are three types of fluorescent circuits: rapid start, instant start and preheat. The preheat circuit was used when fluorescent lamp first came available. This technology is very little used today, except for low-wattage magnetic ballast applications such as compact fluorescents. A separate starting switch, called a starter, is used to aid in forming the arc. The filament needs some time to reach proper temperature so the lamp does not strike for a few seconds.  1, fiche 1, Anglais, - preheat%20circuit
