Replacing ballast in old light fitting - advice from those that know please sought!

Hi everyone

Wow, it's been some time since I was here.... it's all changed! I've not been doing a huge amount of electrical work of late, although now. have a conundrum which I can't seem find out the answer to.. so of course I though of you all. Fingers crossed.


I have a client who is VERY attached to an old light fitting. Its a fluorescent. Having replaced both tubes and starters, its still not working (there is power) so I'm thinking to change the ballast. However, all the replacements seem to be HF which don't require starters. Would it work with the starters? Or would I have to rewire the light to by pass them?


No lighting supplier has proved helpful in answering my query but hopefully someone here can help me out.

many thanks

    I was assuming that I could just cut and join together the wires that go 'into' the starter sockets so bypassing them



    Just to be clear - in the old arrangement the starter is usually in series with the two tube end filaments - in the new one all four tube connections need to go back to the new HF  "ballast"(*) - so it's not just a case of shorting out the connections to the starters and replacing the old wound ballast with the new one. Chances are you'll need some extra wire.


    (*) for a twin tube arrangement usually two tube ends share one circuit, so you have 6 wires back to the ballast rather than 8.
