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?

  • It used to confuse some as it could be had in either 100W or 125W versions too.

    Every xmas it was not uncommon to purchase fairy lights and wire in series with a flu starter, it gave a happy twinkle xmas effect and just about lasted over xmas. Cheap man`s version. Not that I ever did it of course!!!
