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.

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: 1. Does front diffusion come with this item? Which front diffusion would work with this umbrella?

A: While this particular umbrella is meant for diffusion on its own, the Westcott Umbrella Diffuser for Parabolic Umbrella would be compatible. https://bhpho.to/3mO1VGH

Q: 2. Using this umbrella, about how wide of a light throw can you get? In short, if I was photographing a group that is 20 feet wide, and I had the umbrella facing the group (with enough wattage) do you think it would light side to side of the group? Specifically outdoors, where there is no bounce from ceilings?

A: These modifiers throw light about 180 degrees according to Wescott's website. They do recommend using multiple lights for large groups. So Mathematically, beam spread calculations say "beam width = angle x .018 x distance". To cover a 20 foot line of people you would need to place the light 6.1728 feet from the line. So yes! I place it directly behind me centered in the group, slightly above & tilted slightly down just over 6 feet away from the group.

Q: 3. I'm making a large 5'x10' DIY softbox. Is this applicable for that use? How many stops does it decrease the light?
