A current-limit ballast for use in a fluorescent lamp is disclosed to include a bridge rectifier circuit, a filter circuit, a high-frequency pulse transformer, a choke, and a current-limit circuit electrically coupled to the filter circuit and the high-frequency pulse transformer and formed of a silicon controlled rectifier and a current-limit resistor to limit the range of the current to charge capacitors of the filter circuit for enabling the high-frequency pulse transformer to produce a high-frequency oscillation signal to trigger the silicon controlled rectifier.
