Abstract: A triangular extrusion is disclosed which reflects a significant portion of the light into the plant canopy. By the geometry of a triangular extrusion with reflective sides, only a small portion of the light is absorbed and most of the light is reflected into the canopy. An example shade and shadow minimizing extrusion luminaire for a plant canopy includes a reflector and a housing. The housing has two triangular shape ends The triangular shape is defined by angles selected to redirect light impinging on a face of the triangular shape ends of the housing, in both a downward and horizontal direction into the plant canopy without blocking or sacrificing the light.
