hi,

I want to install recessed halogen lights in the bathroom, and I gather
I need to use IP rated lamps in this location.

Packaging in B&Q suggest there are 3 zones in the bathroom, but does not
mention IP ratings, so are these correct?:
- zone 1: directly above bath or shower (IP65?)
- zone 2: within 0.6m laterally of shower or bath, or 0.6m any direction
other wet areas (IP44?)
- zone 3: other areas (IP20?)

They only seem to sell zone 3 fittings. I picked up a jcc lighting
catalogue from a local electrical trade shop, they have some of all 3
ratings though the IP44s look a bit ugly, with a thick glass dome:

The IP65 looks like it might be nicer:

The room is 2.4m by 3.7m. I was thinking of 6 lamps, maybe 35W each: 1
over shower & 2 over bath (IP65?), one would be within .6m of the shower
(IP44?) and 2 near sink & loo (IP20?)

Does this seem OK?

I also thought I saw somewhere that IP65s should be 30mA RCD protected.
True? If so, would it be OK to put an RCD in the upstairs lighting
circuit outside the bathroom - it's the last room in the circuit, and a
shaver socket is the only other connection. Other option would be using
protected slot in fusebox for whole circuit, but I gather lighting
circuits aren't usually protected.

thanks.

also, what should be done above the lamps? do they need a cut out in the
loft insulation do prevent overheating?
