Ballasts for low pressure sodium vapour lamps
The choice between conventional and modern technology also extends into the realm of low pressure sodium vapour lamp operation: electromagnetic copper/iron ballasts require an external igniter. Electronic ballasts, on the other hand, act both as igniter and as capacitor. Compared to electromagnetic ballasts, they consume over 35 percent less power and are also smaller and lighter.
