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 T12 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: 8. Can I use F16, 22, 32 with these tubes. If not what would be the limit, if any?

A: You mean small apertures? Of course, why not? These are merely extension tubes, meaning they're full of nothing but air... All electrical connections are passed on to your lens. Their purpose is to move your lens away from your sensor, adding a magnification ratio which depends on your lens, focal, and distance to subject. Search the web and you'll find plenty of calculations about the actual magnification ratios you can achieve with your lenses. I do not regret buying these cheap but efficient extension tubes.
