A fiber optic luminaire is arranged to couple light energy from a light source (20) along its length. The fiber optic luminaire (10) includes a plurality of light redirecting structures (14) distributed along its length; the light redirecting structures are arranged to uniformly distribute by reflection light energy from the fiber optic luminaire. The light redirecting structures (14) are preferably non-scattering structures, including structures such as microprisms, microfacets, microgrooves and micrometers. The fiber optic luminaire may be configured to a variety of shapes and to provide customized light distribution patterns.
