well obviously the issue is the lights, there can be many reasons why, a dodgy switch, a dodgy connection, a dodgy circuit breaker, the only way is to bite the bullet and get an electrician in, forget the first one you employed, he sounds like a bad one, they are rare, there is no way we can sort this out for you on here without seeing it..
We have a problem in our front bar where a bunch of spotlights aren't working (the bulbs work in other fittings, so it's not dodgy bulbs),
Having said that ...Photos can help/ My first check would be to see what type of fitting or fittings are used. Then also to see how they have been connected .Chances are its a "spur" . If it is and its disconnected . if its a track system etc for pro lighting etc etc . Just buy a new one and have it fitted .Who ever fits it should test it all back to the consumer anyway .well obviously the issue is the lights, there can be many reasons why, a dodgy switch, a dodgy connection, a dodgy circuit breaker, the only way is to bite the bullet and get an electrician in, forget the first one you employed, he sounds like a bad one, they are rare, there is no way we can sort this out for you on here without seeing it.
