Abstract:
1. The lighting method, comprising: providing a voltage to a lamp, the lamp comprising fluorescent lamps; determining a current across the lamp; providing an output based on the current across the lamp; providing an output based on a light setting, wherein the light setting may indicate a desired light level of the lamp; determining a difference between the current across the lamp and the desired light level of the lamp; determining whether a fault or hazard condition exists based on the difference between the current across the lamp and the desired light level; controlling, when a fault or hazard condition is determined, the current across the lamp to go to a safe level or to be cut off; and controlling, when no fault or hazard condition is determined, a voltage frequency applied to the lamp based on the determined difference between the current across the lamp and the desired current level.
