The prevalence of modern guns has made them easier to access and utilize. While weapon lights are a seemingly simple tool, there is a lot to consider when it comes to choosing and employing one.

A weapon-mounted light (WML) is a flashlight that attaches to a firearm for the purpose of establishing positive identification of a target or non-target.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-need-for-a-weapon-mounted-light\">Need For a Weapon-Mounted Light<\/h2>\n\n\n\n<p>The golden question is, &#8220;Do you need one?&#8221; As always, the situation will dictate the need for any tool, and &#8220;need&#8221; can be a strong term. For home defense and duty users, a WML is a competent tool. In terms of need, I do think home defenders and duty users should seriously consider a weapon-mounted light.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863-1024x683.jpg\" alt=\"photo showing four guns each with weapon-mounted lights\" class=\"wp-image-220260\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights9-e1757813759863.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Need is a strong term, but a WML can be extremely handy. I think home defense guns need weapon lights. <\/figcaption><\/figure>\n\n\n\n<p>For concealed carry, the term &#8220;need&#8221; tends to be pretty strong. While useful, it\u2019s not necessary, and it\u2019s typically easier to carry a handheld light than to attach a light to your <a href=\"https:\/\/gunsamerica.com\/firearms\/handguns\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-ultimate-guide-to-weapon-mounted-lights\" title=\"The Ultimate Guide to Weapon-Mounted Lights\">handgun<\/a>. The presence of a WML does not remove the need for a handheld light.<\/p>\n\n\n\n<p>The main advantage of a weapon-mounted light is the ability to maintain a two-handed grip on your firearm, which provides better stability and increased accuracy. It\u2019s typically faster to deploy since the light is drawn with the gun.<\/p>\n\n\n\n<p>The big downside is muzzle awareness. Shooters can fall into a habit of pointing their light while failing to remember they are pointing their gun at it. You have to maintain excellent muzzle awareness when using a WML.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476-1024x683.jpg\" alt=\"weapon-mounted light on PSA JAKL\" class=\"wp-image-220269\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights18-e1757813396476.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">You can&#8217;t start pointing the light at everything. Pointing the light means pointing the gun at everything. <\/figcaption><\/figure>\n\n\n\n<p>As with everything, proper training and practice are critical for utilizing a weapon-mounted light.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-purpose-of-a-weapon-mounted-light\">The Purpose of a Weapon-Mounted Light<\/h2>\n\n\n\n<p>When employing a WML, you must understand its purpose. These are tools used to aim and establish positive identification. It\u2019s not designed for constant searching or to find your keys. Good tactics can allow your weapon-mounted light to bounce light off reflective surfaces and use it for some search functions, but that\u2019s not the primary purpose.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-fundamentals-of-a-light-s-power\">The Fundamentals of a Light&#8217;s Power<\/h2>\n\n\n\n<p>When shopping for any light, you\u2019ll be hit with lots of numbers and terms. These terms are used to explain a light\u2019s power, but also to market the light. It\u2019s wise to understand these numbers and the story they tell.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-lumens\">Lumens<\/h4>\n\n\n\n<p>Lumens is the term that\u2019s most prominent in light advertising. This is the measure of how much light is being generated. The higher the number, the brighter the light. For a long time, there were the &#8220;lumen wars,&#8221; which were light companies trying to out-lumen each other, but the conversation has shifted.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798-1024x683.jpg\" alt=\"weapon-mount lights on a Glock 17\" class=\"wp-image-220271\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights20-e1757813338798.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Lumens and candela work together to create bright light. Lumens and candela are the most important numbers to know. <\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-candela\">Candela<\/h4>\n\n\n\n<p>The conversation is now focused on candela and lumens. Candela measures the intensity of the light in a specific direction. Lumens are the light\u2019s brightness, and candela is the light\u2019s ability to push that light forward. A mix of candela and lumens may call for fewer lumens and more candela.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-lux\">Lux<\/h4>\n\n\n\n<p>We don\u2019t see the term lux mentioned much anymore, but lux measures how lumens land on a specific area. One lux is equal to one lumen spread out over one square meter. Lux level is dependent on both lumen output and distance from the target.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-throw\">Throw<\/h4>\n\n\n\n<p>This term applies to how far the light can go and still be effective. Most light companies will provide a beam distance that seems quite far. That\u2019s as far as the beam can travel, but throw is how far the light can travel while remaining useful. Throw is determined by candela and reflector design.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"771\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-1024x771.jpg\" alt=\"SIG FOxtrot-MSR Compact beam\" class=\"wp-image-208649\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-1024x771.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-398x300.jpg 398w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-768x578.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-1536x1157.jpg 1536w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/10\/sig-foxtrot-msr-compact-range-2048x1542.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Throw is powered by candela and your usable light. <\/figcaption><\/figure>\n\n\n\n<p>High-throw lights act as a spotlight, while low-throw lights act as a floodlight. There are some benefits to both designs. For indoor use, a floodlight beam fills your field of view. High-throw spotlights are useful outdoors when distance is king. Certain platforms benefit more from specific types of throw based on their effective range.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-hot-spot\">Hot Spot<\/h4>\n\n\n\n<p>A hot spot is the brightest part of the light. It sits at the center and is the concentrated part of the beam. The hot spot is where your focus is put when using a weapon-mounted light.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-spill\">Spill<\/h4>\n\n\n\n<p>Spill is the area around a hot spot. It is less intense but provides peripheral vision illumination to see a wider area around the hot spot.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-corona\">Corona<\/h4>\n\n\n\n<p>Corona is the portion of the light\u2019s beam that sits between the hotspot and the spill. It\u2019s a small ring of light that\u2019s brighter than the spill but dimmer than the hotspot.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"486\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42-1024x486.jpg\" alt=\"SureFire X400 Vampire Delivers both Visible Light, IR Light, &amp; IR Laser - Review\" class=\"wp-image-145093\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42-1024x486.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42-400x190.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42-150x71.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42-768x365.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/05\/x42.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Hot spot, corona, and spill are the parts of a beam that matter<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-reflecto-r\">Reflecto<strong>r<\/strong><\/h4>\n\n\n\n<p>The hotspot, corona, and spill of the light come down to the light\u2019s reflector. If you look into the front of a light (make sure it\u2019s off, fellow crayon eaters), you\u2019ll see the bulb and a shiny reflective surface. That shiny surface is the reflector.<\/p>\n\n\n\n<p>Reflectors are what direct light forward. The shape and texture of the reflector are key to creating a light\u2019s distinct beam. Most weapon lights will have a purpose-built reflector designed to propel light further and ensure a particular hot spot.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-temperature\">Temperature<\/h4>\n\n\n\n<p>Temperature doesn\u2019t refer to the light\u2019s heat. Powerful weapon lights get hot, and most even have a warning. Temperature, when we talk about light, refers to the light\u2019s hue. Temperature is a spectrum and is measured using Kelvin.<\/p>\n\n\n\n<p>A low kelvin, or low-temperature light, gives you a warm, yellowish light. Mid-range temperature lights are typically neutral white lights. High kelvin numbers have a bluish tint.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929-1024x683.jpg\" alt=\"Steiner MPS: Enclosed-Emitter Micro Pistol Sight mounted to an ACRO cut Brownells slide mounted on my Glock 19\" class=\"wp-image-175730\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/02\/IMG_3929.jpg 1170w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Temperature measures beam hue, not heat. <\/figcaption><\/figure>\n\n\n\n<p>Temperature matters when it comes to being able to determine colors. Warm or cold lights can affect your ability to perceive specific colors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-modes\">Modes<\/h2>\n\n\n\n<p>WMLs can often have a multitude of modes that determine how you can use the light. A variety of modes allows you to tactically employ the light most advantageously. Most weapon lights are pretty simple and typically have one to three modes. Your tactics and situation will dictate which mode is employed.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-constant\">Constant<\/h4>\n\n\n\n<p>Constant is the most common mode you\u2019ll find across any form of flashlight. When you hit the button, the light comes on and stays on until you turn it off. This constant mode is often employed when aiming at a fixed threat or target. It can also be used to provide light to clear complicated malfunctions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight-1024x576.jpg\" alt=\"Streamlight weaponlight down an alley\" class=\"wp-image-213691\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight-1024x576.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight-400x225.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight-150x84.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight-768x432.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/03\/1200x675-streamlight.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Sometimes you need your light for a second, sometimes you need it constantly.<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-momentary\">Momentary<\/h4>\n\n\n\n<p>Momentary modes allow you to activate the light for only as long as you need. Typically, a momentary mode will activate as long as the activation device is held down. When released, the light will automatically shut off. Momentary is used to avoid having the light constantly on and to prevent potential threats from tracking your light. It\u2019s for situations requiring brief illumination to identify obstacles and threats.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-strobe\">Strobe<\/h4>\n\n\n\n<p>Strobe modes are the constant on and off of a light. This mode is typically used to disorient a threat and help disguise the user\u2019s position while illuminating the danger. The use of strobe has largely fallen out of favor on weapon-mounted lights and in modern tactics, although many will still feature the mode.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461-1024x683.jpg\" alt=\"2 - Streamlight TLR-10G Weapon Mounted Laser\/Light Review\" class=\"wp-image-173079\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2023\/01\/IMG_2461.jpg 1170w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The laser is easily visible even when 1000 lumens is lighting up the target.<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-intensity-controls\">Intensity Controls<\/h4>\n\n\n\n<p>Some lights will allow the user to control the lumens and candela generated by the light. This is commonly referred to as high and low modes. This can help preserve battery, as well as allow the user to prevent reflections of light that can disorient them in some environments.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-wml-design\">WML Design<\/h2>\n\n\n\n<p>Just as we accept a diversity in firearm design with rifles, shotguns, and handguns, there are different light designs for these platforms.<\/p>\n\n\n\n<p>The differences will be in size, activation method, and mounting method. Some lights can cross-pollinate between different guns. For example, a pistol light can fit on a shotgun or rifle easily. Is it the best option? Possibly, depending on the light and the gun\u2019s purpose.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318-1024x683.jpg\" alt=\"Pistol and rifle with lights side by side\" class=\"wp-image-220251\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/09\/weapon-mounted-lights6-e1757814830318.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Pistol lights can mount to basically anything, but long gun lights are more specific due to their size and design. <\/figcaption><\/figure>\n\n\n\n<p>However, rifle lights aren\u2019t going to work well on pistols due to their size and attachment method.

This can be due to length, rail slots, and the size of the gun. Most companies feature modular rail keys to accommodate a variety of different weapons.&nbsp;<\/p>\n\n\n\n<p>Some companies have proprietary rails. For example, some HK weapons like the USP have a proprietary rail that may require an adapter to fully function.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-m-lok-and-keymod\">M-LOK and KeyMod<\/h4>\n\n\n\n<p>For long guns, M-LOK and keyMod <a href=\"https:\/\/gunsamerica.com\/digest\/seekins-precision-accessories-shot-show-2019\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-ultimate-guide-to-weapon-mounted-lights\" title=\"The Ultimate Guide to Weapon-Mounted Lights\" data-wpil-monitor-id=\"21\">systems provide a direct mounting system that doesn\u2019t need a rail<\/a>.

With weapon-mounted lights, you\u2019ll find a diverse set of battery options. There are some general rules of thumb when it comes to batteries and WMLs. First, always use good-quality batteries to get the most light and battery life possible.<\/p>\n\n\n\n<p>Additionally, quality batteries are less likely to leak or break under recoil. Always pay attention to the manufacturer\u2019s recommendations for batteries. Just because a battery fits doesn\u2019t mean you should use it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754-1024x683.jpg\" alt=\"Included with the RAID is a 3500mAh 18650 rechargeable battery\" class=\"wp-image-211551\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754-1024x683.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2025\/01\/IMG_7754.jpg 1353w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Some special lights need special batteries.<\/figcaption><\/figure>\n\n\n\n<p>Speaking of recoil, shotguns can be hell on batteries. Recoil can break batteries, but not quickly. If you train with a shotgun and fire dozens of rounds, it might be an issue. I suggest removing light batteries if you\u2019re not training with a shotgun in low-light conditions.<\/p>\n\n\n\n<p>When choosing a light, pay attention to the batteries required and make sure they are widely available and not priced out of your budget.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-rechargeable-or-standard\">Rechargeable or Standard<\/h4>\n\n\n\n<p>Some lights use rechargeable batteries, others use disposable batteries, and some can use both. Modern rechargeable batteries can hold more &#8220;juice&#8221; than disposable batteries. They are more expensive, and while useful, once they die, you either need a second rechargeable on hand or you\u2019re out of luck.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-1024x768.jpeg\" alt=\"Surefire Rechargeable CR123. weapon-mounted light\" class=\"wp-image-151625\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-1024x768.jpeg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-400x300.jpeg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-150x113.jpeg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-768x576.jpeg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-1536x1152.jpeg 1536w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2021\/09\/IMG_0719-2048x1536.jpeg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Surefire makes some awesome rechargeable batteries. <\/figcaption><\/figure>\n\n\n\n<p>Disposable batteries allow for quick and easy &#8220;hot swaps&#8221; in the field.

This can simplify logistics and help you power your light in multiple situations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"600\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/streamlight-protac-cr123a-aa-lights-7.jpg\" alt=\"Dual Fuel Multi-Battery Lights. weapon-mounted light\" class=\"wp-image-63477\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/streamlight-protac-cr123a-aa-lights-7.jpg 900w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/streamlight-protac-cr123a-aa-lights-7-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/streamlight-protac-cr123a-aa-lights-7-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/streamlight-protac-cr123a-aa-lights-7-768x512.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\">Dual Fuel lights allow you to switch between battery types.<\/figcaption><\/figure>\n\n\n\n<p>When using dual-fuel designs, be aware of power changes. Some lights may emit lower power when paired with certain battery types. There can be a drop in lumens and candela with certain battery types.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-protected-batteries\">Protected Batteries<\/h4>\n\n\n\n<p>When using rechargeable batteries like 18650s, you must use protected batteries. These batteries feature a small internal circuit board that acts as a safeguard. This prevents overcharge, over-discharge, short circuit, and overcurrents.<\/p>\n\n\n\n<p>Protected batteries can protect your light, which is already an expensive investment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-things-to-consider\">Things to Consider<\/h2>\n\n\n\n<p>When it comes to weapon lights, there are a lot of little considerations you have to make. Most of these don\u2019t belong in a particular section, but still deserve mentioning. This is the leftovers, if you will.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-holster-use\">Holster Use<\/h4>\n\n\n\n<p>If you\u2019re equipping a handgun with a weapon-mounted light, you need to consider a holster. Depending on the gun and the light, finding a holster might prove difficult. You have to keep this in mind when shopping for a <a href=\"https:\/\/inside.safariland.com\/blog\/surefire-xsc-mini-and-mighty\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-ultimate-guide-to-weapon-mounted-lights\" title=\"The Ultimate Guide to Weapon-Mounted Lights\" target=\"_blank\" rel=\"noreferrer noopener\">weapon light<\/a> for your gun.

The light creates a shadow, which gives you a blind spot in your light\u2019s beam. Depending on your setup, you can work to eliminate barrel shadow or reduce it. It takes some configuration, but it\u2019s not a major problem.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-keep-them-clean\">Keep Them Clean<\/h4>\n\n\n\n<p><a href=\"https:\/\/www.pewpewtactical.com\/best-pistol-lights\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-ultimate-guide-to-weapon-mounted-lights\" title=\"The Ultimate Guide to Weapon-Mounted Lights\" target=\"_blank\" rel=\"noreferrer noopener\">Weapon lights<\/a> typically sit close to the end of the barrel. As such, they get really dirty from carbon. When a light gets dirty, its performance is compromised. After shooting, you should clean the light.
