Berore checking out the wiring regs I had bought a light to go above
my mirror in the bathroom.

It's not 600mm away from the bath though - maybe 300mm so I think I
can have mains but must me IP4.

I've looked for another nice light but cannot see any - is there
anyway to use an energy efficient light bulb in this light and keep it
where it is?

I guess I could use a 12v halogen bulb and holder and an SELV - there
is plenty of room behind the glass to fit other bulbs etc but that's
not very efficient - also a nice effect of the light is that some
light shines out the sides which would not happen with a halogen since
it is directional.

The reg's seem a bit daft in that this light isnt' really far away
from the main bathroom light (it's a bit higher) and it woud be close
to a shaver socket as well (though there is no provision for a
seperated HV light) ho hum.
