AR-15 Flashlight Buying Guide

Features to Look for in an AR-15 Flashlight

Before you pick up a flashlight for your AR 15, it’ll be helpful if you pay attention to these key aspects before finalizing a purchase.

What Are You Using It For? – Not all AR 15 flashlights are built for the same purpose. Some flashlights are better for home defense and won’t be necessarily as bright. In fact, those lights will likely be a little dimmer to prevent you from blinding yourself in a home defense situation. Alternatively, hunting scenarios likely be much brighter to help you find camouflaged animals in the darkness. Tactical lights will have better batteries and may be even more powerful.

The idea is to pick up a light that’ll best suit your purposes rather than just the most expensive pick on the market.

Brightness – Of course, brightness does matter a great deal when it comes to the ideal tactical flashlight for your needs. Most flashlights measure their brightness with “lumens”, with higher numbers corresponding to a brighter light. Weak flashlights will usually have around 100 lm, while more powerful ones will have lights of 1000 lm or higher.

Go for dimmer flashlights if you will primarily be using the light indoors or for home defense situations. Go more powerful of the light will be used outside; light spreads out when outdoors, meaning you’ll need a more powerful beam to reliably illuminate anything.

Battery – Don’t forget to consider batteries when you make your decision. Some flashlights have rechargeable batteries, which are great for value for money, although they may also be more expensive. Others have disposable batteries, but these have another disadvantage in that you have to constantly carry additional batteries on a hunting expedition.

There’s no right or wrong answer when it comes to the power supply. It all depends on your preference. But you should always try to find an AR 15 flashlight that has enough battery power to last for many hours. Otherwise, you may run out of illumination at a particularly bad time.

Durability – Finally, it always pays to pick up a durable flashlight instead of a weaker one. Durable flashlights last much longer than their cheaper competitors, and they often come with special coatings to let them last in water or inclement weather. We’d recommend you go with a durable and “weatherproof” flashlight if you can afford it; it’s a flat-out better choice than the alternative.


All in all, the best AR-15 flashlight for your needs may be totally different from our own! Remember to keep the key aspects in mind as you browse. Whatever you need, one of the above 8 is probably a great fit for your build. Good hunting!
