Get good quality lights -- they go a long way.

If you are using halogen lights, remember: They heat up easily, so it is important to have an acrylic cover that diffuses the light.

If you want ambience lighting, tall floor lamps are an interesting option, since there is a wide range to choose from.

You could also have a reading lamp near the bedside.
