Rosco, founded in 1910, is still best known for the products it originally manufactured: filters for entertainment lighting.
The company now offers products in more than a dozen categories. These include gobos (or patterns), correction filters for film lighting, fog and haze machines, dance floors, scenic paint and backdrops for theatre and film/video.
Rosco also has innovated a number of lighting equipment products, including rotators, projectors, intelligent mirrors and LitePad, a remarkable LED-based fixture.
The company has been honored with four awards from the Academy of Motion Picture Arts and Sciences (the "Oscars"). The awards were for Rosco's Cinegel range of lighting filters and the CalColor range of lighting filters. Other awards were won for the company's backdrops and fog machines.
