1. A plant growth lighting fixture comprising:
a lighting fixture main body having a light exit surface;
a light source held on the lighting fixture main body; and
a reflective-type circularly polarizing film that selectively reflects circularly polarized light having a particular rotational direction in a particular wavelength range,
wherein the reflective-type circularly polarizing film is releasably affixed to the light exit surface of the lighting fixture main body,
wherein the reflective-type circularly polarizing film has a circularly polarized light reflecting layer that selectively reflects circularly polarized light having a particular rotational direction in a particular wavelength range, an adhesive layer for releasable affixation to the light exit surface of the lighting fixture main body, and a support, and
wherein the circularly polarized light reflecting layer is disposed on one surface of the support, and the adhesive layer is disposed on a surface of the circularly polarized light reflecting layer.
