An exemplary directional light homogenizer includes a one-piece, hollow hexagonal cross-section tube. The tube has an internal highly light reflective surface. The tube defines a first end configured to receive a non-homogenous light from a light source and a second end configured to output homogenized light. At least one curved section is disposed between the first end and the second end, and the curved section has a curvature greater than zero degrees and less than one hundred eighty degrees. An output section of the tube is straight, has a finite length, and terminates at the second end.
