This Red Filter from Nitecore is a flashlight accessory that will fit a light with a 60mm bezel diameter. The filter lens is made of glass and is coated on both sides for enhanced light transmission and heat tolerance. An impact-resistant rubber frame makes this filter durable; it also has an integrated lanyard attachment hole that offers convenient carrying. Since its lens can be removed, this filter can also be used to protect the flashlight bezel.

Q: 1. 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.
