Great fit, but low light - SureFire Diffuser for 1.125in Diameter Bezels

I got all three: red, blue, and white diffusers/filters. There is no problem with a snug fit, but the Red and Blue Diffusers both greatly reduced the light along with filtering the light to a different color. Perhaps it is good if you don't want to be found when using it, but if you are hunting with it then it is very poor to see more than about 10 yards out which is way unacceptable for hunting most game that can be hunted at night. I don't mind so much with the blue because it is mostly for tracking blood that shouldn't be too hard out to 10 yards, but red needs to be much brighter to detect animal eyes. The plain white light diffuser does what it should which is make the white light of the X400 which is normally more lumens than car headlights into something a whole lot less giving away your position.
