Steamproof downlights

["Peter Church" <yahoo@xxxxxxxxxxxxxxxx>]

I've been having recurrent problems with one of the 12v downlights
installed in a 'floating' shelf beside the cooker in our kitchen -
the bulb often flickers and blows repeatedly.  The fitting is a
Screwfix cabinet downlight and I've replaced the fitting and the
problem resumes.  Another light on the same circuit has no problem
so I can rule out the transformer (Aurora btw...)

Other than the wiring, the only thing different between the two
lights is that the dodgy one sits above the kettle - and I can
imagine how that could cause corrosion on hot contacts of the
capsule bulb.

Does anyone have any experience of a similar problem, or better has
anyone got a similar situation and not got the problem and can
suggest a better fitting.

I'm thinking of resorting to an IP rated fitting (not sure where
steam comes in the IPxx ladder...), but as the small depth is an
issue might have to resort to some expensive marine fittings.

Any thoughts

TIA Pete
