8 ft. Switch start fluorescent batten fitting.

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?

  • If anyone wishes to keep an 8 foot fluorescent light fitting working, then it is worth fitting an electronic starter in lace of the more commonly used glow starter. 

    Only a short term measure as AFAIK the lamps are no longer manufactured, and remaining stocks are becoming hugely expensive.
