This technique creates smooth, even illumination of selected objects or large wall areas. It can create visual interest and possibly provide area lighting through reflection. Changing the light fixture spacing will create different effects. Similar to grazing, creating an even illumination.
This technique is very efficient because it highlights the wall and then reflects a soft, glare-free ambient glow onto the surrounding area. If this effect is used on a wall adjacent to walkways or driveways, it can eliminate the need for traditional path lighting.
