I may be wrong (I was once before, in 1996)
, but I think the question may have been misunderstood. I think Juicybag has a new light fitting, which she wants to screw onto the wall, and get power to. What she doesnt want to do is have it 'hard wired' into the lighting circuit. What she basically wants to do is 'stick a plug top on it', and plug it into an existing wall socket.
If this is the original question, then
presuming it is a 240volt light (that is the supply to the light is 240, it doesnt matter what lamp is fitted),
and the light is fed by a suitable flex, then the answer, AFAIK, is yes, you can just stick a plug on it (with the correct size fuse).
Being a wall light, it almost certainly IS 240 volt, as its pretty much impossible, or at least impratical, to have a wall light with a 12 volt supply. However, the fact that it has 2 wires, the same colour, in what looks like bell wire makes it sound as though it is 12volt (is it a foreign light i.e from Ikea?). Whether it is 12 or 240, the cable feeding the light does sound a little suspect, so without seeing it, I would say you
should definatley NOT stick a plug top on it.
If I've misunderstood
, then just look the other way, and pretend I'm not here
