An orientation specific luminaire is coupled to lensed optics configured to illuminate vertical and horizontal surfaces within elongated spaces at predetermined light intensity levels, where needed, and with predetermined uniformity ratios within a surface and between surfaces. The orientation specific luminaire includes an orientation mounting hub, the orientation of which is user settable such that the lensed optics emit light from the luminaire's light sources to illuminate vertical and horizontal surfaces within elongated spaces at predetermined light intensity levels.
