I was going to say anywhere, but looked at Homebase and realised they tend to do 1 spot then jump to 3 or more.
There are 6 or 7 of varying styles at B&Q, a few at Debenhams and John Lewis, plus any lighting shop local to you should have catologues you can pick through.
I have quite a few multi-spotlight setups currently and I am going to swap them out when I next decorate (more on that below). I just dont like the unevenness of the light they shed across a room. Maybe down the stairs (would it be shining straight in your eyes though!) and in a hallway would be alright.
Regarding decorating I have big news too, my planning permission went through
My neigrabroadours are FUMING though and had no hesitation in telling me so!
Oh, and you're place is looking good!
