Integrated fluorescent ceiling light goes dark after about 20 seconds

Hi

Does the above indicate that the unit needs to be replaced?

Perhaps, check that all the fittings are secure.

If it doesn`t light up, when switched on..... or keeps "trying" but never quite makes it.... or maybe sometimes it does.... fault is usually the little starter cartridge

Going "dark"  after being switched on... sounds like the tube needs replacing.... ( a new starter for the new tube at same time would be good idea ) .

Yep I know nothing about DIY.

It could be the bulb is on the way out, or a dodgy starter. For what they cost I would replace both. Does the bulb switch on straight away, or does it take some time flickering beforehand? If so, then both may need replacing.

Can't see it being a wiring problem, otherwise it wouldn't work at all.

@Alex 

Can you post up a picture of the light fitting?

It might give us a better idea.

Thank you all.

I disconnected the power wires from the light and connected a  simple bulb socket to check the wiring and that worked fine. So the original is now in the bin.
