A reflector configuration where the reflector surfaces intersect a beam of beam light from least two sides, and are oriented at an angle intersecting the cross section of the propagating beam. The reflectors are further characterized as allowing passage of unreflected portions of the beam to be successively re-directed by other reflectors along the propagating path, where the total lumens reflected and redirected is substantially the same over a given beam propagation distance.
