What is the maximum allowed distance between a luminaire and the wall in a workspace?

In workspace environments, the maximum allowed distance between a luminaire and the wall is set to ensure adequate illumination and avoid any visual discomfort or hazards. According to the National Electrical Code (NEC), specifically referencing Article 410, the preferred distance is typically 12 inches. This distance helps to ensure that light is distributed effectively over the area, providing sufficient brightness for tasks while minimizing shadows that can occur if the luminaire is placed too far from the wall.

Ensuring a proper distance of 12 inches also accounts for the potential need for maintenance or bulb replacement without excessive risk of damaging adjacent structures. Maintaining this distance is vital to achieving optimal lighting conditions in workspaces, thus enhancing safety and productivity.
