Rosco's premier range of filters, Roscolux, is manufactured to ensure the longest possible life under hot theatrical lights. Three (3) discrete layers are combined in a tri-extrusion process. By sealing the colored layer between two microscopically thin layers of clear film, dye migration is minimized and effective life is extended. Roscolux is currently the most widely used filter range in the world.

Roscolux gel sheets measure 20" x 24".
