hi all

fitted 4 halogen downlighters in the bathroom a while back. They are
the design with 2 wire clips, whereby the act of pushing the
downlighter into place grips the clips, and swivels them to spring
against the ceiling to hold them in.

3 are fine, but one, for some reason has the plasterboard cumbling a
bit. This has enlarged the hole slightly and reduced the grip the
light has.

Anyone know of a way to reinforce the hole in the plasterboard to
prevent further damage and ensure the light stays in place ? I'm
imagining something made of metal which can be fed round the hole and
curved into place ....

*If* you can get to the other side of the hole, you could fit a piece
of some sort of heat resistant material such as formica above the
hole, with a fresh hole cut into that.
