Landscape wall lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses. Like many things in life, less can be more—and this is the case when it comes to landscape wall lighting. Your instinct might be to light up everything: every detail, every tree, every nook and every cranny. But besides potentially running up your power bill, this will wash the yard out.
