Just imagine the warm, yellow-green hue reminiscent of traditional gas lighting fixtures. That's the unique color effect you get with the Roscolux Gaslight Green, 20x24" Color Effects Lighting Filter. This filter is perfect for adding a touch of nostalgia to period pieces like La Boheme, or for simulating the natural reflections you'd see in fields and meadows. With a light transmission rate of 76%, it offers a balanced blend of color and clarity.The Roscolux range, also known as "Supergel" in international markets, is Rosco's premier line of filters. It's not just popular; it's the most widely used filter range globally, thanks to its innovative manufacturing process. This process involves a unique tri-extrusion technique that seals the colored layer between two ultra-thin layers of clear film. This design minimizes dye migration, extending the filter's effective lifespan under the demanding conditions of hot theatrical lights.The Roscolux Gaslight Green filter is made from two types of plastic. Over 65% of the filter is crafted from co-extruded polycarbonate plastic, while the rest is deep dyed polyester. This is a significant upgrade from ordinary color filters, which are typically made by surface coating clear polyester plastic film. With the Roscolux filter, the color isn't just painted on the surface. Instead, it's integrated into the material, making it resistant to heat and physical abrasion. This means less fading and scratching, and more longevity.
