The Tiffen 5 x 5" CC20G Green Filter is a color compensating (or color correction) filter for use when making color balance adjustments. It can be used to alter the color balance of a scene by placing in front of a light source or the lens of your camera. It can also be used to apply color corrections when used in the darkroom with an enlarger or to help pre-visualize color adjustments when viewing prints.

Green is the opposite of magenta and can be used to reduce magenta tones or casts within a scene or print. This green CC20 is more dense than a CC10 filter and less dense than a CC30 filter, and requires a 0.3 stop compensation for normal exposure results.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 5 x 5" / 127 x 127mm.

Q: 3. Can you tell me exactly what model # flashlights these filters along with the other colors and defusers fits as I want to get a flashlight that works with this type filter & defuser one that has the rubber type housing & lanyard hole. Will they work with the XML-T6 or UltraFire C8 ?

A: You will need to check the head diameter of these flashlights. It needs to be 1.6 (4.0 cm) at the head diameter to work with these filters. Many of the better known flashlights - Surefire, Nitecore, EagleTec, Fenix, etc have standard head diameter sizes of there high-end tactical lights. I'm not familiar with UltraFire. XML-T6 is a Cree LED type and comes in many flashlight brands. Check for the actual flashlight model and then check for the head diameter. On a quick web search for the UltraFire C8 it looks like the head diameter is 45mm. Not a standard filter size and so the filter above will not work. But check the specs before a final decision. The 40mm filters also come in red, blue, sometimes yellow (rare) and a white light diffuser. You might also check the flashlight manufacturers site for models of their filters - they may be custom.
