ABSTRACT OF THE DISCLOSURE A light fixture including a louver assembled from blades formed of thin metal strips. The blades each have separate parabolic lower sidewalls and upper sidewalls. The parabolic upper sidewalls terminate in edge strips which overlap to close the blades when the blades are nested to form the louver. Nesting of the blades forces the sidewalls together against a resilient bias, the bias tending to rigidify the louver after assembly.
