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.

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
