Rosco Fluorescent Lighting Sleeves/Tube Guards are a very 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, every cinematographer.

For T5 Lamps    Over 300 Colors Available    UL94HB Rated Polycarbonate    End Caps Protect From Shattered Glass    Easily Trimmed with Scissors

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

Q: 7. I just bought these tubes for my Nikon D7100. I cannot set the Aperture with these tubes. I'll adjust my camera to F/11 and the aperture remains wide open at F/3.5. You can see the aperture not move while you scroll the aperture adjustment wheel. Could it just be I have a defective set???

A: The aperture does not move when you scroll, it opens or closes only when a photo is taken. You may test this by setting the aperture first to f/22, which should give you a fairly dark image. Then, try setting the aperture to f/5.6, which should produce a much lighter image.
