The function of the filament at both ends of the flourescent tube is to ionize the gas inside by heating for producing the light. Once the gas is ionised then the filaments have no role to play. The choke and the starter as just means to produce the high voltage spark due to the inductance property of the choke, which later on just reduces the AC voltage for the tubelight to around 90 volts which is enough to stay ignited.

There is no such thing as a Generator. All power generating devices are Alternator since both generate alternating current since this is the only way electrical power can be generated. In "generators" the alternating current is converted into DC inside the housing of the "generator" in order to give out DC Do you agree? If not please educate me. How else is DC generated if not like above?
