Can you give me any idea of the spread of light from these, as an indication of how far apart to position them.
The spread of light you get from a fitting like this is dependant upon the beam angle of the lamp that you install in it. The typical beam angle for an MR16 lamp is 38º however we often supply soffit kits with 60º wide angle lamps. Using a little bit of Pythagoras you can work out that a 60º lamp mounted at 4 metres is going to cover an area of 6 metres at ground level (if the lamp is powerful enough to reach the ground!). Realistically we would generally suggest placing these fittings every 2-3 metres, especially as they have a frosted diffuser.

What is the exact size of the bezel diameter?
80mm.

I'm looking for a lamp similar to this but with a white surround - and wondered if you know of one? We want a frosted glass, white, IP65, 12v soffit downlight (and I'm having a devil of a job finding one!).
This downlight is available in White - we've just not got around to listing it yet. Call or email us on Monday for details.

Do IP65 12V downlights meet the Code for Sustainable Homes requirements: 'The fitting must be dedicated in that it must be capable of only accepting lamps having a luminous efficacy greater than 40 lumens per circuit Watt'?
Downlights of this size are made with either a GU10 (mains voltage) or MR16 (low voltage) lamp holder suitable for halogen lamps. Halogen lamps have an efficacy of approximately 20 lumens per watt, and whilst a GU10 compact fluorescent lamp with a high enough efficacy could be retrofitted they are not strictly part L compliant because you are not using a dedicated lamp holder. Try taking a look at our High Output IP68 LED as an alternative.

Is IP65 Soffit Downlight - 12v Silver Grey Zone 1 compliant? (bathroom)
Yes. Zone 1 requires an IP rating of 44 minimum, this fitting is in fact IP65 rated.
