I use fairy lights that are in her room over her curtains that have white balls around them (that sounds weird!) and they give off a nice soft light for changing her nappy, but I find that to feed her I turn on the light in the next room and almost shut the door and thats enough light for her to feed. Its surprising how little light you need.
A BB friend has Candelas (google candela lights) they are portable and recharge on a base, look great and you can definately use them post baby/nursery! They are expensive but look fantastic!

ETA- I also have one of those sensor lights in the plug in the hallway that comes on at night, great for not falling over with baby in a sleep deprived state in the middle of the night!!
