Hello,

We had a conservatory installed about six years ago, and one of the
12V halogen spots has worked itself loose from one of the metal
aluminium ridge struts. The strut itself is about 6cm thick, and the
diameter of the spot that recesses into the strut is about 2.5cm.The
spot uses a narrow G4 2-pin halogen bulb. It is held in place in the
strut by two spring-loaded clips that clip behind the strut, and one
of these clips has broken off, with the result the spot hangs lop-
sided, held in place by the other clip.

I haven't been able to find a supplier for these spots. Can anyone
help?

If possible I would prefer to use a Gu5.3 halogen spot holder and
bulb, but none of these is narrow enough to fit in the available
space. The hole in the strut that takes the current spot is about 3cm.

Can anyone recommend anything?

Many thanks,
Paul
