Nitecore NFB26 26.8mm blue filter for flashlights

Nitecore 26.8 mm diameter blue filter for flashlights. Turns the light from the lamp blue. The blue filter is ideal for hunting because it makes the blood visible (makes it black), making it easier to find an injured animal. Blue light does not attract insects/repel mosquitoes. Works well with night vision devices. Produces less disturbing light and is also suitable for card reading. The filter withstands extreme temperatures well, it is made of reinforced anti-reflective glass. The frame is made of high-quality rubber, which is flexible and therefore easy to install. The device also has a small lanyard hole. If the lens is removed, the filter can also be used as a self-defense nozzle for a flashlight.
