The tube light cannot function without a choke. High voltage is required for ionisation of the argon gas in the tube light which is generated by sudden break of the circuit by the starter. The value of high voltage will depend on how fast the contacts within the starter opens. If due to aging the contacts within the starter is not opening as fast as it should then also the tube will not work as the Choke could not generate the required high voltage. Once the tube light comes on the starter will be out of the tube light circuit and if you remove the starter nothing happens to the tube light. Because the current takes shortest path of from filament to the filament through the ionised gas and the starter circuit is bypassed. The function of the choke, once the tube light comes on, will be to limit the surges in the input voltage.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
