Armytek Filter AF-39 for Viking / Predator flashlights

Blue Filter

Blue filters are often used when reading maps or other writing because they cast black lines in stark relief against white paper. If you are on an overnight hike or mission, a blue filter will certainly help to keep you on the right path.

One of the additional uses of blue filters is for hunters. Tracking wounded animals at night means picking up a blood trail. The blue light helps the blood stand out against foliage.

In many situations it pays to have colour filter options – especially when you want to see but not be seen.

Green Filter

Green filters are used mostly in hunting and tactics. Green light has a very narrow band. For that reason, it is often used for night hunting. Animals are not frightened by green light, and it cannot be seen from the side – only straight on. This makes it the ideal filter for your tactical flashlight when stealth is at a premium.

With the human eye being most sensitive to the green range of light this makes it an optimal color to use when traversing through the forest when you are using a low intensity.

Red Filter

Red light does not detract from your night vision. That is why taillights are red. By using a red filter over your tactical flashlight, you can quickly read a map or get your bearings without destroying your night vision and being forced to wait for your eyes to readjust. Red also makes a great signal light because of its use as a distress signal across cultures.

It has been one of the most popular choices to add as an optional filter.  It’s popularity has led flashlight manufacturers to include a colored led light as an option.  With having a colored red led light integrated you can get the benefits of the light without  having to put on the filter.
