I have a couple of fluorescent light fittings in the house, each containing two fairly standard tubes and two 120 volt starters. I know the starters need to be 120 volt ones because I discovered a few years ago that 240 volt ones won't start the lights.
I think I need some new starters again, but every electrical & lighting shop I've tried so far doesn't have them, and a quick WWW search only shows them in the USA (where they are obviously useful).
Are double-tube fittings wired this way obsolete now?
