Abstract

Certain embodiments of the invention may include light fixtures, retrofit and conx ersion apparatuses for recycling, condensing and diffusing light According to an example embodiment, a method is prcmded for converting a light fixture into a light recycling, diffusion and condensing apparatus The method includes arranging one or more optical films into a film stack, wherein the film stack is characterized by at least one lenticular lens surface and one di ffusion surface The method includes suspending the optical film stack adjacent to an aperture associated w ith the light fixture. The method can also include inserting one or more reflection films or surfaces between one or more lamps associated with Lhe light fixture and an existing reflector or back surface associated with the light fixture, wherein the one or more reflection films or surfaces ha\ e a reflectivity of over 90%.
