Abstract
A fluorescent lighting device includes a ballast and a tube. An amalgam is located within the tube. A resistive heater is operatively coupled with the ballast, to receive electrical power from the ballast while the fluorescent lighting device is in an OFF state. The resistive heater is mounted near the amalgam to transfer heat to the amalgam while the fluorescent lighting device is in the OFF state.
