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.
However a grid of pot lights is not all you need for a balanced light scheme. Notice that this space also includes a pendant sconces and art lamps (more on those later) as well as a full wall of windows. Including at least three layers of light from different categories and in different locations eliminates strong shadows and adds a sense of sparkle that allows all the other furnishings to look their best.
Bright idea for unexpected lighting: Look for opportunities to install light fixtures in alcoves tray ceilings and wall niches to trace interesting lines. Notice the hidden lights in the ceiling alcove above the cylindrical fireplace mantel here.
