Abstract
An improved lighting fixture includes a light reflecting and/or light transmitting member for reflecting or transmitting visible light. A light transmitting film is disposed adjacent the light reflecting or transmitting member. The light transmitting film is formed of a glutarimide acrylic copolymer. The glutarimide acrylic copolymer film provides protection to the light reflecting and/or transmitting member from damaging effects of ultraviolet radiation and is substantially resistant to ultraviolet radiation.
