This is an accessory package with both the Red and Green Filter Adapters for the MF Tactical R5-350-1 and R5-350-5 flashlights (NOT compatible with the compact R5-350-1C+ or R5-350-3C+ models). These filter adapters easily replace the standard clear lens and bezel assembly. Just unscrew standard bezel and screw on the color Filter Adapter in its place. This lenses are made of hardened mineral glass, which are resistant to scratching or breakage. They will also outlive and outperform similar products made of plastic.
A red filter protects your night vision. Under low-light or no-light conditions using white light can impair your night vision for up to a full hour. Using a red lens reduces this affect, allowing re-adjustment to full night vision in just a few minutes.
A green filter is used when you need more light, but you don’t want others seeing you easily. Green light diffuses much more quickly than do other colors, so your beam is not as easy to see from a distance.
