The kitchen, like the bathroom, is a place where lighting brightness and functionality are more important than appearance. Still, kitchen lights can be attractive too. Much depends on the fixture.
Kitchen lights need to be bright but cool, so fluorescents light bulbs are ideal, but kitchen spotlights also serve important purposes. They shine bright lights on food being prepared and let the cook see what's what. Lean toward the functional, but look for looks as well—it's an important room.
