Abstract
The present invention discloses a control module that provides improved control over the ignition of a fluorescent lamp. In one aspect, the control module determines whether the lamp is lit and, when the lamp is not lit, determines whether the power supply line voltage is insufficient to sustain the lamp in a lit state after ignition. When the power supply line voltage is determined to be insufficient, the control module waits until the power supply line voltage rises to a sufficient level before igniting the lamp.
