Flourescent tube lights in Gymnasium

[1shortcircuit]

A friend of mine has asked me to pop over and see why one of his fluorescent units is not working in the changing rooms.

The only information I have at the moment is that it's a double strip light unit and he's tried swapping them over with known working replacements and still no light.

There is no starter visible externally.

Am I correct in thinking that it's likely cause could be that the transformer has failed? Obviously I will check all terminations when I am there but my initial thought is that it is this as the unit has been in use for approx 18 months and now both tubes are no longer working?

Assistance very much appreciated.

Regards

1shortcircuit, hi mate.
The picture of the reception area shows a four pin lamp holder and the next picture shows a two pin lamp.
I will be corrected when I say this but, I am sure these pl lamps need to be matching, ie two pin lamp/two pin lampholder and four pin lamp/four pin lampholder.
If you are already aware, then my appologies.

I hadn't spotted this so Thank You for pointing this out. I am only familiar with domestic premises so this is the first time I have come across these types of units.

Thanks again, I will look at this more closely. If someone else is able to advise on the compatibility then it would be much appreciated. I guess I'll be checking the other units as well now
