I'm not absolutely sure it was being used as an earth but I wired the new light up and it seems to work fine. The dimmer switch however does make a faint buzzing noise which makes me a bit nurvous so I may get someone in to have a look at it.

Thanks all. It turns out the second black was the earth with a black sleeve placed over it.

I am installing a new downlight and would like to connect to an existing cable which previously connected to a wall light via a dimmer switch. The transformer on my new light has a live and neutral connection but the existing cable has a live red wire plus 2 neutral? black wires. I'm not sure...
