In an earlier comment I remarked that I've never been a fan of downlighters, having grown up in the 1950s to the dim, but welcome glow from a pendant lamp hanging from the ceiling. Downlighters are too harsh. I don't think they are the right kind of light for domestic dwellings. More suitable for shops, or light industrial premises perhaps.
Then while I was having my usual soak in a warm bath I pondered and thought, why couldn't I just fit pendant lights instead? I would disable all but two of the downlighters in the kitchen (where the lights are on more than anywhere else in the house), then convert the two remaining ones, one at each end of the kitchen, to pendants.
I would disconnect the 12V transformers and connect a ceiling rose direct to the brown terminal box. So I wouldn't need much at all. A couple of ceiling roses, bulb sockets and cable (I've got plenty of suitable cable).
The henceforth unused downlighters: They would just be disconnected and the bulbs left in place in case a future owner wanted to revert back to downlighters.
Sounds like a plan?
