This 3' long Rosco #3203 3/4 Blue CTB Fluorescent Lighting Sleeve/Tube Guard is a reliable and cost-effective system for easy control of tough lighting scenarios, especially under fluorescents. In addition to the financial benefits of the sleeves, they protect against the potential disaster of glass shattering by containing the lamp within the end caps.
Rosco sleeves are constructed of a solid polycarbonate tube within which is held the specific filter. The choice of filters and combination of filters is endless; there are complete Roscolux, Cinegel, or E-Colour color filter lines, something for every venue, every photographer, and every cinematographer.
Not suitable for use with HO (High Output) or VHO (Very High Output) lamps due to excessive heat generated at the electrodes. This includes T5 and T8 lamps.
Available in sizes for T12, T8, and T5 fluorescent lamps
The T8 and T5 sizes contain a UV filter that minimizes fading
All standard sizes (2, 4, 5, and 8') are easily trimmed to accommodate any size lamp
