   A dimmable ballast is very similar to a rapid start ballast, except that the autotransformer is connected to a dimmer. A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the ...

   A quick-start ballast eliminates the need for a starter switch, a common source of lamp failures.

   Once the tube strikes, the impinging main discharge keeps the cathodes hot, permitting continued electron emission without the need for the filaments to continue to be heated. The starter switch does not switch on again because the resistance in the tube drops and the voltage across the starter is insufficient to start a glow discharge again. [2]
