Best Practices for Site Preparation and Installation of In-Grade Fixtures

摘要

Some projects demand that designers find a way to distribute light upward from the ground in highly trafficked outdoor areas. Recessed in-grade luminaires are the solution for uplighting features of an architectural structure or landscape, without creating a tripping hazard or maintenance obstacle in the area of intrigue. The in-grade luminaires are recessed into the ground and installed flush with the walking surface, enabling passersby to admire the sculpture, column, or canopy of trees and move safely through the space. Achieving the desired illumination goals with these luminaires requires many of the typical considerations that are made when selecting any luminaire, interior or exterior, such as reviewing the light distribution pattern and evaluating the energy needs and lamp life of the fixture. These recessed in-grade fixtures also require attention to details that are less typical in the sphere of lighting fixture specification, namely, the type of soil available on a project and the drainage it can provide.
