Electronic and magnetic ballasts
Lamps with electronic ballasts do not require a separate ignition system, as it is integrated in the ballast. In the case of fluorescent lamps with magnetic ballasts, a starter is used for ignition.
High-pressure lamps
High-pressure mercury lamps ignite at mains voltage, whereas high-pressure sodium lamps and metal-halide lamps can only be ignited with the help of a suitable igniter.
Igniters
A distinction can be made between superimposed pulse igniters, in which the ignition voltage is generated in an integrated high-voltage transformer, and impulsers, which deliver impulses to the ballast to generate the high voltage required. Superimposed pulse igniters are subject to a maximum permissible distance between the lamp and the igniter (e.g. 1.5 m).
