ABSTRACT:
A method according to one embodiment may include supplying power to plurality of External Electrode Fluorescent Lamps (EEFLs). The method of this embodiment may also include generating signals proportional to the voltage of each EEFL. The method of this embodiment may also include generating a feedback signal indicative of the state of one or more of the plurality of EEFLs based on, at least in part, the value of at least one signal proportional to the voltage of each EEFL. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
