Recessed spots - hole too big!

My wholesalers would sell the fitting without lamp and transformer for about £3.

If there were 4 lights to change for slightly larger ones I would not mess about trying to make the holes smaller even if I had to pay a little more than £3 per light.

Cut a hole 200mm diameter. Cut new plaster board same diameter to fit hole. Cut new hole in centre of new insert with tank cutter for MR16. Fit a coup le of wooden battens say 8-12mm thick 20 mm wide 250mm long screw them into the ceiling with plasterboard screws black coloured into the enlarged whol e so it misses the new MR16 hole. Fit new plasterboard screw into battens. Fill gaps and screw head recesses. The springs for the MR16 fitting should fit between battens.

Nice one perry... you do realise you are answering a question posted over two years ago?

Could be worse. There's some other arsenugget suddenly replied to a 15yo query...

Sometimes it does take that long to get jobs done :)
