IP65 light fitting in bathroom zone 2?

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.

    If it says MINIMUM IPX4 then any classification above that is fine.


    The wording of the reg is subtly (but I think significantly) different - "...have at least the following degrees of protection ... zones 1 and 2: IPX4" - i.e. the minimum is on the requirement rather than the numbering.  As above we can't presume that an IPX7 or IPx8 will also satisfy IPX4 - so IP X4, X5 or X6 would be OK, but IP X7 or X8 might not be.
