The Important Factors for a Good Flashlight

Brightness

Obviously, the most important feature of a flashlight is how bright it is. However, having the brightest light may not always be useful. The ideal brightness for indoor needs would be around 80 to 100 lumens and for outdoor needs, it can be up to 500 lumens. Picking the best brightness should depend on your purpose of use.

Battery

The type of battery that the flashlight uses will determine how long it lasts and while rechargeable batteries give you value for money, it will also cost you more. Others like disposable ones are cheaper but they can be more inconvenient as you have to keep changing the batteries and carry extra while hunting. 

There is no best battery for AR-15 lights, it all depends on your personal preference and how long you want to use the flashlight for. Some can only last 1 to 1.5 hours while some can last up to 20 hours so choosing the best one for yourself will depend on how long you need your light to run. 

Durability

Even though some flashlights are cheap and can be replaced easily, it will still be nice to have one around that you know you can count on and can last longer than others. The best type of flashlights to go for are those that are resistant to impact and weatherproof. It allows you to use the flashlight for a long time without causing any problem. 

The Pros and Cons of an AR-15 flashlight

Pros:

Versatile – Having a light for your AR-15 can be helpful in many situations like hunting in the dark or even identifying your target in self-defense to make sure you don’t shoot someone else.

Cons:

Takes up space – Some of the models of the flashlight may be bigger than other models and can take up quite a lot of space on your rail. With lesser space, you also have lesser options of optics to mount on your rifle.

Frequently Asked Questions (FAQ)

Q: How bright should a weapon light be?

The ideal brightness that you should go for is the minimal amount of light. Normally, the reflection of 100 lumens of light is enough to blind you in a dark room. So for home-defense uses, ideally you would want something less bright. For using a flashlight outdoors, 500 lumens is enough as the reflection is enough to blind you in dark woods. Generally, 150 to 200 lumens will be the ideal brightness for all purposes. 

Q: What side do I mount my weapon lights?

Mounting your flashlight forward on the handguard of your rifle would be the best as it will not get in the way of your support hand. You should also mount it in the opposite direction of your body to prevent it from tangling with your gears. For instance, a right-handed shooter should mount the flashlight on the right side of the gun. 

Q: Do you need a weapon mounted light?

Depends on the situation. If in any case, you need both hands on your gun, weapon mounted lights can put you in an advantageous position by keeping your extra hand free. Compared to holding a flashlight and your gun at the same time, a weapon mounted light is able to allow your free hand to hold other gears or support your gun. But if you do not need your free hand, you can choose a handheld flashlight as it can be cheaper and you can mount other accessories on your gun.
