A floor lamp nestled against a window is a smart substitute for daylight so that when the sun goes down an ambient glow will pour in from a similar direction to balance the central light overhead.
Wall washers either installed on the wall or aimed down from the ceiling are used mostly to highlight decorative features such as an art piece or a textured finish like a brick wall. However the psychological effect created by lighting the walls can make the whole room feel much brighter.
Track lighting got a bit of a bad reputation in the 1990s but when used properly it is still functional and beautiful especially for the kitchen. Pot lights aimed straight down will add general illumination but not necessarily hit the counter. An angled ceiling light on a track can put task lighting exactly where you need it. Undercabinet lighting can also achieve a similar effect. Combining both will make task lighting in the kitchen look effortless.
