Patterns, or gobos, are widely used by designers in theatre, film, photography and television to create atmosphere, project scenery, and generally enhance the visual impact of their lighting.

Conceived by some of the world's leading lighting designers, the Rosco range presently includes hundreds of standard steel gobo designs.

To insure design integrity the patterns are etched using a precise double-sided process on stainless steel. The result is durable, high quality patterns which will withstand the extreme heat at the gate of ellipsoidal spotlights.

Rosco steel gobos are round to allow for rotation in the gate when aligning the projected image.

The standard "B" size is suitable for most fixtures with a 6" lens when used with a Rosco Pattern Holder or the holders of other manufacturers.

Trimming of patterns, where necessary, can be easily accomplished with a pair of scissors.

Related Questions and Answers

Q: 1. Can I use this in Elinchrom 250 heads?

A: Yes, it will fit in the 250 heads.

Q: 2. Does the paper accept the lead from a mechanical pencil? If you rub the page do the pencil marks smudge? Do you have to use a number 2 pencil? I want to be sure I can read the text (not too light) and when writing, not smudge the page from my wrist resting on the paper. Thank you!!!

A: Hi Julianne, Any pencil will work on Rite in the Rain paper. Pencil lead acts the same on our all weather paper as it would on normal paper. I hope that helps!

Q: 3. Is there a CRI rating available for these lamps?

A: Unfortunately, Impact does not specify the CRI rating for this lamp.

Q: 4. Does anyone know the CRI of this? Looking for 93 or so. I've Alzo bulbs in other unit and trying to match.

A: The best bet for matching a CFL is to use the same brand. https://bhpho.to/2GNqn8L

Q: 7. What size is this orange notebook? (The Overview and Specs are greyed out...)

A: The size is, 6.875" x 8.5" x .375".

Q: 8. What is the length and tungsten equivalent wattage?

A: The bulb is approximately 11 inches long. Fluorescent lights just like LED lights are not rated in watts but in lumens. They do not compare well as Quartz lights have about the best throw of light. Meaning light from fluorescent and LED lights will not go as far or as bright. A rough estimate on that bulb is that it is like a 100-125 quartz bulb.

A: yes

This bulb is pretty good. I used this to light a green screen for my film and it did a good job.

I have tried twice, locally, to find these bulbs. Within 5 minutes of my contact with B & H, I was given the number to order to replace my bulbs for my Interfit constant lights.

I'm been using 2 of these lamps for a couple of weeks and am very satisfied with the quality. I do non-pro product photography as well as of before & after collectible restoration projects. The following in no way reflects on this product but isn't uncommon; my 9-foot light stands came with 'mushroom' style CFL bulbs a dozen years ago. Those bulbs are somewhat obsolete and the cost with shipping has doubled. I knew that these looked close but might not fit. They bottomed out 1 thread short. I found a $2 product called a 'socket extender' and now they fit but the lamp extends beyond the shroud which makes controlling the side light difficult. Bottom line; a great product with a great price.

I actually bought this item to use as a natural like light source for my house. The bulbs are larger than normal lightbulbs but fit fine in my fixtures. I contacted Impact from their website and they said the bulb was 5600k but they did not know if they were full spectrum including ultraviolet. Also, they make no noise like reviewers said about some of the other manufacturer's bulbs.

What can I say, these things never call out, never late to work, always on time...flip the switch and they know to whip the darkness's butt right out of your life. Real game changer. They're definitely not scared of the dark.
