Filters

A white beam at night gives a hunter away faster than sound or scent. A boar at the feeder lifts its head, freezes and slips into the thicket before you settle the rifle. A colored filter cuts that risk: red or green light looks dim to a game animal's eye, so it stays calm while you judge distance and target.

Why a flashlight filter matters in night hunting

A filter slips over the flashlight head and changes the beam color. It suits hunters who wait for boar at feeders or hunt foxes and raccoon dogs after dark and want to light the animal without spooking it. By day the flashlight stays universal: the filter comes off in seconds.

Colored light also dazzles you and your neighbor in the high seat less, so your eyes return to night vision sooner.

Filter types in this category

The category holds original Olight filters in two colors and for different models: FSR51 series filters in red and green, plus a red filter for the M22, S80 and R40 lights. All are factory accessories matched to the head diameter, so they sit tight and stay silent on the move.

Red filters

Red light disturbs game eyes the least and barely degrades your night vision. It suits waiting in a high seat, when the animal is close and needs a careful look without being pushed off. The red options are the Olight FSR51 Filter-R and the filter for M22, S80 and R40 flashlights.

Green filters

Green light gives more contrast and helps you pick out detail against a dark background, which is why many hunters choose it for boar in open fields. The Olight FSR51 Filter-G V2 covers that role.

FSR51 series filters

FSR51 filters fit the larger Olight heads. Before ordering, check your model against the maker's compatibility list or write to us.

Filters for M22, S80 and R40 models

This red filter fits the compact Olight M22, S80 and R40 lights, which hunters mount on a weapon or carry as a backup light.

How to choose a filter

Two things decide the choice: your flashlight model and the kind of hunting. The wrong diameter falls off the head, and the wrong color means a spooked animal or too little contrast for the shot. Work in this order:

1. Check your flashlight model and head diameter: the filter has to match exactly.
2. Decide on color: red spooks game the least, green gives better contrast.
3. If you run both a weapon-mounted light and a handheld flashlight, plan a filter for each.
4. Test the fit: you should be able to put the filter on and take it off with a gloved hand in the dark.

Practical advice in the field

Filtered light is weaker than white, so test before the hunt how far you can identify an animal. Shine at a familiar object at 50 and 100 meters and note what you see.

Light the animal with the edge of the beam and move it slowly. A sudden bright spot pushes a boar away even through a red filter. Keep the filter mounted all night so you are not digging through pockets at the decisive moment.

Olight accessories

Every filter here is an original Olight factory accessory, shaped for a specific flashlight head, so it keeps the beam shape intact and survives the rain, mud and cold of autumn and winter hunts.

The lights themselves sit in flashlights, weapon-mounted models under tactical flashlights, holders and remote switches in mounts and remotes, chargers in chargers and batteries. If you are unsure a filter fits your light, write to us and we will advise.
