Phil,
The pyramidal sockets can either go where you describe or lower, at the angle between the worktop surface and the wall; but in fact I'm still undecided between using them and conventional flush mounted sockets; hence the discussion about false walls and hollow-wall mounting boxes.
That makes sense, but my units don't have a pelmet (and would look slightly odd with one fitted, I think.) What about downlighters set into the base of the wall units? Are there any shallow enough? I suppose I could fit false cupboard floors to cover the lights and cabling.
Sorry, that strikes no chord with me at all. I have absolutely no idea what you mean... (g)
