IP65 light fitting in bathroom zone 2?

Farmboy:

Electrical equipment in zone 2 in a bathroom must be rated at minimum IPX4 (excluding shaver units...), so, can an IP65 (circular bulkhead style) light fitting be used in zone 2? Mention was made elsewhere that IP ratings are not cumulative, suggesting that e.g IP65 would not be suitable in a minimum IPX4 area.

Did we really have any serious problems years ago with a bare 60 Watt filament bulb fitted in a bathroom ceiling "Home Office" skirted batten holder.


Fires, shock, explosion or world society meltdown?


Z

Arguably not. I was just interested by the non cumulative aspect of IP ratings, suggesting a fitting may not be suitable as first thought. I was aware of the separation of figures, etc, as AJ points out, but would've thought that a higher water index would have assured adequacy in a location, when exceeding a locations minimum requirements, but apparently not in all cases.
