On kitchen fixtures, I argueably did the house a favour when I put my knee through the ceiling. I'd gone up to do some plumbing job, a badly corroded joint just snapped and somehow I slipped. We had soggy plasteboard coming down in the kitchen. Parents got someone in to replace the whole ceiling in there.

Before, it had 3 downlights and a central light but the chaps doing the ceiling suggested the row of GU10 spots on a bar. It turned out better and as I said before is even better with the LED bulbs in.

Kitchen btw is own room where the lights are turned on and off by sensors. Corridor is the other one. It's quite handy especially as we eat in the living room. There is no need to worry about turning lights on and off when carrying plates.

I also use a sensor in the living room. It's a cheap foscam web cam clone. Seems better at detecting occupancy. It just sends emails to a server that I managed to cobble up in Python. The system uses that as a motion trigger. It's main use has been to shut the lighting down if no ones in for 30 minutes. Pre LED, there were 4 x 60W candle, 3 x 60W table lights and 4 x 35W MR16 spots. It shuts things down to one table light (now 10W) on.
