"Can anybody tell me of the relative advantages/disadvantages of going
low voltage or mains voltage for this lighting?"

One of our rooms have a light fitting using 4 mains powered GU10 bulbs
and I can guarantee a bulb will blow every 3 or 4 months. Surprisingly
the bulbs that have lasted the longest so far are the cheap twin packs I
got from Poundland! If I fitted another one I'd pay extra go for a
transformer low voltage type.
