The Real Job of a Pathway Light

A landscape pathway light is not a decorative trinket that happens to shine. It is a piece of site furniture with a specific job: to illuminate a horizontal plane so that a person can see where they are stepping and where they are going. It should reveal changes in elevation, surface texture, and any obstruction that might cause a fall. It should not blind the person walking toward it. In practice, this means the lens, reflector, and lamp must be designed to put light on the ground in a controlled pattern, not to scatter it in all directions.

Consider a typical front walk made of four-inch-thick concrete pavers. The distance between the joints is small, but in the dark, a two-inch difference in elevation is enough to turn an ankle. A properly placed path light at 18 to 24 inches in height, with a beam angle of 30 to 45 degrees, will throw a soft pool of light that overlaps with the next fixture, creating a continuous band of illumination. The eyes then take in the whole plane, not just a bright spot near the fixture. This is the fundamental concept you are designing for: not individual pools of light, but a continuous, even corridor of visibility.

The term "pathway lighting" is often used loosely to describe anything that looks like a small post with a lamp. But the category includes a wide range of fixture types:
