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.
Painting with light is another way to add surprise. Here colored LED lighting with toe kick lights underneath the island and cabinets creates dramatic appeal.
Adding lights to stair risers is beneficial since it can be hazardous negotiating stairs especially at night. Staircases are often enclosed so light them from the sides or embed lights in the risers as a design element.
