  • Things to Consider When Buying the Best AR15 Flashlight



    Now that you have gone through the list of products, you should already be feeling quite confident about making your choice. However, at this stage, you should take a step back and think about your requirements.

  • What do you expect out of the flashlight?
  • Is it for military application or hunting?
  • Do you want the flashlight to be removable?
  • As you can see, these are all important questions that often get overlooked in all the hassle of balancing out the expense. And let’s face it, flashlights for AR15 are not exactly cheap. But if you want to make the most out of your purchase, you need to understand a few key concepts about the tool.

    In the following section of the article, we will give you a thorough rundown of things you should consider when buying the best AR15 flashlight so that you can get a better understanding of the device.

    • Intended Purpose

    Before investing in a particular AR15 flashlight, take a moment to consider where you might use it. This device is quite versatile and is suitable for a plethora of applications. Figuring out your requirements is the first step to ensuring you are making the right choice.

  • Home Defense:
  • If you want to use your rifle from home defense, you do not need to spend a lot of money. You want a basic tool that allows you to install it with minimal hassle quickly. The priority, in this case, is the ease of use and quick installation so that you can react to a break-in with the least amount of time.

    You do not need too much brightness either. Since you are dealing with an intruder inside your house, a lumens count of 60-200 should be enough. That way, you will not have to worry about the light reflecting off the surfaces and disrupting your vision. However, try to find a unit that gives you decent peripheral lighting to help you cover wider distances.

  • Hunting:
  • When it comes to hunting, you need to go a step above with the flashlight. You need brighter light along with a lasting battery to ensure you get the most out of your purchase. Remember, hunting takes place outside, so the higher the lumens count, the better performance you can get.

    Hunting also involves waiting for long hours stalking your prey. For that, you need a decent battery so that you do not run out in the middle of the hunt. Some models offer different light modes that allow you to switch between distances. These units are great options for hunting, as you often need to hunt from a long-range.

  • Tactical Application:
  • If the flashlight is used for tactical application, you really cannot afford to skimp out. You need to ensure you get the best performance, along with some adjustment options to use when you need to. Choosing the wrong unit for tactical applications can often lead to disaster.

    Make sure you have the option to adjust the brightness. Furthermore, one must-have illumination mode that you should have is strobe light. Both peripheral and primary illumination should be decent to give you a comfortable experience. Some flashlight comes with a filter that turns down the brightness automatically when you move indoors. This feature is excellent for tactical applications.

    • Lumens of the light

    Understanding how the brightness works is essential to figuring out which unit will give you the best result. The unit of measurement for brightness is lumens. With a higher value of lumens, you can expect the light to be brighter while a lower value means dimmer light.

    For indoor use, a lower lumens value might, in fact, give you a better result. The higher the lumens, the more reflection you have to deal with, especially in an indoor environment. However, for open spaces, higher lumens typically give you a better performance. With higher lumens, you also get a wider beam of light that can help illuminate the peripheral areas.

    • Intensity of the Light

    In terms of illumination, brightness is one thing, and the intensity is another. For intensity, the unit is Candela. This unit is important if you want to understand how wide the beam will spread from a light source. The higher the candela value, the higher the intensity of the emitted light.

    For indoor usage, you want the candela value to be lower as it would help keep your visibility higher. With greater intensity, you will get a wider beam to enlighten a larger area. However, when using indoors, having a lower candela rating will help keep it focused and comfortable for your eyes.

    • Battery life and Efficiency

    An Ar15 flashlight is only as efficient as its battery. When the battery runs out, you either have to replace it or go on using the rifle in the dark; none of the choices are very appealing. So in order to get the most out of your flashlight, you need to make sure that it uses its battery efficiently.

    Thankfully, just by looking at the spec sheets, you can get a general idea of how long the batteries in the unit will last in different power modes. So make sure you are going with a unit that gives you enough uptime for your particular application. For home defense, you do not need to get a massive uptime; however, for hunting and tactical application, the better the battery, the better the performance.

    • Weight and Durability

    When it comes to an AR15 flashlight, it is always a compromise between weight and durability. If you want your light to survive for a longer period, you need to find units that use metal components that can, in turn, add to the weight of the unit. Lighter products are typically less durable and can take less abuse.

    If you want to keep the weapon’s weight on the lighter side, you need to invest in a lighter flashlight. For that, the material of choice is a polymer. Although this material is lightweight, the durability is quite good. However, it cannot match the strength that you would get from a strong aluminum device.

    For people who do not need to worry about weight, aluminum is always the way to go. Although it might be a bit heavier, the durability more than makes up for it. The bulky nature of the material ensures that your flashlight will survive anything and everything you throw at it.

    • Ease of Use

    You also want your flashlight to be easy to mount and use right out of the box. For that, you need to go with units that offer tool-free mounting. Most of the rail-mounted flashlights can be installed in moments without any hassle. These are a great option for just about anyone.

    In a practical home defense scenario, when you are reacting to a break-in, you will not have enough time to fiddle around with tools to get the flashlight running. Additionally, you could even find products that allow you to remove the flashlight. With this option, you can use it as a standalone flashlight, which further enhances its versatility.

    • Additional Modes of Lighting

    A flashlight may or may not feature multiple lighting modes. However, our recommendation would be to find a unit that offers at least two other lighting modes. This feature enables you to get even more out of your investment without any extra hassle on your part.

    Strobe mode, for instance, is a must-have feature that helps you signal in case something goes wrong. You can also find a low or high mode to adjust the brightness of the light, or even momentary illumination mode that keeps the light turned on for a smaller period of time.

    • Control Options

    Finally, you should also consider how you have to activate the flashlight. Some models require you to tap on the flashlight itself to activate it. This might sound okay in theory; however, reaching for the flashlight in a real-time gunfight might take too long.

    You can even find units that come with a pressure switch that you can position on the grip of the gun. These units are excellent as you can simply grip the weapon, and it will turn on automatically. So before investing in a flashlight, take some time to consider how you have to turn it on.
