Abstract: A fluorescent lighting device includes an arc tube, an exhaust tube extending from the arc tube, and an amalgam. A resistive heater is located adjacent to at least one of the arc tube and the exhaust tube. A power supply circuit is operatively coupled with the resistive heater. When the fluorescent lighting device is switched from an OFF state to an ON state, the power supply circuit temporarily energizes the resistive heater, thereby heating the at least one of the arc tube and the exhaust tube while the resistive heater is energized, and automatically de-energizing the resistive heater after said heating.
