8 ft. Switch start fluorescent batten fitting.

Zoomup

I came across one of these yesterday. It has failed. I suspected the series capacitor had gone open circuit. The choke winding was continuous and the tube looked o.k. The fitting was removed and a new one fitted.

So, having forgotten the theory, how does the circuit work with an 8 ft. tube and a choke and series capacitor? What is the principle of operation?

    We had an 8 foot flu lamp in part of my old works twas my first job. I remember sometimes the tube would be reluctant to strike especially in winter. I also know that we suffered from low mains there we had a transformer as part if the test set up  supposed to give us 500 volts for 240 in sometimes could only manage about 495 ish even on the 220 tap on the primary. Any how one day this light wasn't going to come on it had been about 10 minutes already so I stood under it and said come on tube today would be nice then flash flash it lit my boss laughed his head off after that 5hey called me flu lamp girl Lol
