The T5 x 60" RoscoSleeve #3152 Urban Vapor from Rosco is used to produce a specific visual effect for stage and photographic pursuits. The sleeve is made from a polycarbonate and the filter is placed inside. The combination produces a creative effect that has a wide variety of uses. The sleeve comes with two end caps that hold the lamp in place even if the glass shatters. The filter not only adds the color effect but serves to prevent any shattered glass from falling should the tube break. A built-in UV filter is included to help prevent the filter from fading prematurely.
