Can I use 2.5mm cable for lighting, or do I have to use 1.0mm or 1.5mm ???

yes but its harder to work with inside ceiling roes and more expensive. Why not just get 1.5 mm??

There are not many occasions where you would want to use 2.5mm cable for lighting. As Gees has already said, you'll find it really hard to terminate into most domestic lighting accessories. The only time I've used 2.5mm for lighting is to minimise volt drop or due to the collective load of fittings (large external fittings) or because some snotty consultant wants to cover his a**e by massively oversizing every cable on the project

Actually, I just ordered the wrong cable... just wondered if I could make do.

It's not for use in ceiling roses either, it's in a commercial building, just fluorescents...

Thank for confirming what I was secretly thinking (yeh right!).

Flourescent lights usually have a large choc block in them for connection puroposes so you may be ok.

Thing is if you install them in a commercial premises it's in a commercial building you could be liable to prossecution if anything goes wrong (hopefully it wont) and as you are not a qualified electrician you will not be insured

just a thought

Choc block - you mean those plastic things that come in various lengths, to connect cables together? Yeh, there is one in each light.

This premises currently has 6 lights in there, and the light switch downstairs turns them all on/off.

Since we are partitioning the upstairs into 3 rooms (and a bo.. sorry, toilet), I am going to reposition 2 lights into each room. 2 rooms will have an independant switch, whilst the other two (and an additional third in the toilet) will be switched from the original switch downstairs.

If you fancy telling me how to connect it all up, I'm all ears, but I have got a pretty good idea anyway

Cheers!

seeing as you will be adding new independant switches you will (probably) have to rewire all of it, since if you don't the origonal switch will still turn every thing off
