The Blue Filter F06 from SureFire is a slip-on blue filter that is dedicated to flashlights with a 1.0" bezel.
The smooth prefocused blue beam of light from your SureFire flashlight can be used to track wounded game at night. Bloodstains stand out more distinctly against foliage when viewed under blue light. This blue filter produces a light beam with a reduced output level and intensity that is also suitable for non-tactical operations, such as low-light map reading, or accompanying Fido on a nocturnal stroll around the block.
