Best Glock Lights [2020]

For those of you who use their Glock for home defense, everyday carry (EDC) or any real world application, you should definitely invest in a high-quality light for your Glock. When hand-picking lights, we consider a few aspects including reliability, output or brightness, beam configuration, compactness, battery life, and last but not least, ergonomics. The reliability of your weapon light should be measured in its ability to handle weapon recoil and withstand combat conditions. The output of your weapon light needs to be versatile enough to locate threats at both medium and close range, such as having a flood and a spot beam settings, and for the much vexed topic of brightness we believe more is (usually) better. Depending on your setup, the compactness of your Glock should also be considered since some might value comfort and concealment, while others might just be focused on home defense.

Why do you need a light for your Glock?

At the time of writing this article, the FBI has reported there is about one burglary every 13 seconds, and a large portion of those happen at night. To be safe, especially when you have other people in the house, you will need to know what you are shooting at! If you are not worried about break-ins but still use your weapon for self-defense, a light can disorient your attacker and give you those few extra life-saving seconds. Along with blinding your attacker, a light can also help with follow-up shots andadding a little extra weight to the muzzle; the weapon light can act as a counterweight to prevent muzzle rise after each shot.

With that said we have handpicked a few lights we think are the best options for Glock owners. Now without further ado, the lights.

Best Compact Glock Light

Streamlight 69250 TLR-7
Streamlight 69250 TLR-7
  • 500 Lumens
  • waterproof up to 1 meter for 30 minutes
  • 1.5 hours of continuous run time
  • User enabled strobe function

Starting at the top of the list, the TLR-7 is second to none in the world of handgun light mounts. The TLR-7 boasts a 500 lumen output (note: too bright not too dim), programmable strobe, ambidextrous switches, machined aircraft aluminum, shock-mounted glass lens and the list keeps going on. This light just about checks all the boxes, from ergonomics, durability to being waterproof.

The TLR-7 doesn’t have the highest amount of lumens but is extremely compact, striking a great balance between size and ability. The TLR-7 has an evolved on/off switch to prevent accidental activations, either from holstering or un-holstering. The actual light beam produces a concentrated beam with optimum peripheral illumination, creating a great balance between flood and spot beams. It can easily light up a room while still providing a strong focused beam to blind any threat. For the price of the TLR-7 and the punch you get in such a small package is what separates this light mount from the others. The TLR-7 would be a great buy for anyone who values quality and compactness for there Glock.

Best Glock Light Laser Combo

Streamlight TLR-2 Or TLR-2 HL(G)
Streamlight TLR-2 Or TLR-2 HL(G)
  • TLR-2: 300 Lumens; TLR-2(HL): 800 Lumens
  • waterproof up to 1 meter for 30 minutes
  • 2.5 hours of continuous run time
  • User enabled strobe function

Streamlight has a large portion of the tactical light industry cornered with their expansive list of products, so it’s no surprise they appear once again on our list. The TLR-2 comes equipped with a machined aluminum body, IPX4 rated design for water resistance and much more, which can be seen on the product description. The TLR-2 comes in two versions, the standard and the HL (high lumen) model. The main differences between the two models is the lumen output and the laser specs/color. The standard TLR-2 has a 300 lumen output and a red laser compared to the HL which has a 800 lumen output and a green laser.

When it comes to choosing between the two, it depends highly on the application you are intending to use it for and your comfort level with high lumen lights. You can get around most of the shortcomings of high lumen lights with adequate training and techniques when deployed indoors. The downfall of using a high lumen light is you can get bounce back from light-colored walls and mirrors when clearing rooms or spaces, which can disorient your vision. If that is something that worries you, then it may be wise to go with a lower lumen light to prevent the bounce back. If you will be using your light primarily for the outdoors, you can't go wrong with a higher lumen light such as the HL model. As for the TLR-2, it is incredibly durable and can keep its zero after a good amount of abuse which is not an easy quality to find with lasers. The durability and versatility of this light makes it ready for just about any application you can think of, and should be a contender for any one looking for a laser with there light.

Best All Round Glock Light

SureFire X300U
SureFire X300U
  • 300 Lumens
  • 2.5 hours of continuous run time
  • User enabled strobe function

The Cadillac of pistol lights is here, the SureFire X300 is another top tier light that delivers. Being a bit bulkier than the other contenders, this light will definitely be a good option for the full-size Glock’s such as the 17, 17(L), 34 etc. The X300 throws 600 lumens, has an ambidextrous switch, and an optional pressure-activated switch for precision control without altering grip on your weapon. This is an awesome feature that can enable you to deploy or disable the light the second you need it. Since this light is on the larger side, the tip of the light can protrude beyond the muzzle. Having a light that protrudes will get lead build up that does not clean off easily unless you scrape it off (you can use an AR cleaning scraper, or another scraping tool). Luckily, the lens build up is harmless but can get annoying to clean every once on a while.

The X300U is a great weapon light but if you are going to want something that produces more light, your in luck since it has a sister product the SureFire X300 Ultra X300U-B. The “B” X300U-B differs from the “A” model by making it a little harder to remove aka doesn’t have a quick release. Not having the quick release may not be an issue if you don’t plan on interchanging the light on different pistols all the time. The SureFire X300U-B/A also is waterproof up to 1 meter and has 1000 lumen output which is huge. With that amount of light you can easily use it for umbrella lighting (shining it on the ceiling to light up the room). The light itself is very neutral, not too warm or too blue, this is nice since I'm not a fan of either one of the extremes, but the X300U-B definitely hits a sweet spot. The X300U-B is the crème de la crème, but at that price point it is not for everyone since there are other options listed above that will still hold up to most people’s needs.

Best Glock Light For the Money

Streamlight TLR-1
Streamlight TLR-1
  • 800 Lumens
  • 1.75-hours of continuous run time
  • User enabled strobe function
  • waterproof up to 1 meter for 30 minutes

The TLR-1 is the best Glock light for the money, it has the quality of Streamlight products and not to mention is equipped with 800 lumens of output, waterproof up to 1 meter, constructed of aircraft aluminum, and a shock-mounted glass lens just like the higher end Streamlight contenders. If that doesn't check all your boxes I don't know what will. The TLR-1 is so great we believe it is the best light in the 100 dollar range at the moment.

The Streamlight TLR-1 is a perfect size as well, not as compact as the TLR-7 and smaller than the TLR-2 (since it does not have the laser). This light is a great move for someone who doesn’t want to spend an arm and a leg, but still wants a quality product that can perform under most conditions. Since this light is so popular it has been battle tested by the crowds, and we have not personally seen ours fail over the years on any of our setups.

When it comes to the baby Glock's, there are not many light options, but lucky for you there are some quality ones on the market that would go well with your miniature Glock.

Best Light for Subcompact Glock's

Viridian Reactor RTL
Viridian Reactor RTL
  • 100 lumen constant light and 140 lumen strobe mode.
  • 40 Lumens of bright light with horizontal light dispersion.
  • Includes Instant-On ECR holster.
  • 60 min in constant light mode, 120 min in strobe mode and includes low battery indicator.
  • Built specifically for the Glock 19 and 23 and weighs .78 oz.

Viridian is another popular weapon light brand and offers a variety of products. The Viridian Reactor RTL is a quality, feature-rich light built to last. The Reactor RTL is an extremely versatile light and is compatible with quite a few popular mini Glocks including the Glock 42, 43 and 23. This light is our definite go to, and has some notable features such as the "instant on" feature. No more fumbling with buttons or knobs, when you draw the gun the light instantly turns on (take note-this feature only works with the paired holster).

Best Glock 42 & 43 Holster

Crimson Trace Glock 42 & 43 Laserguard with Tactical Light and Laser
Crimson Trace
  • Over 2 hours of battery life
  • Brightest laser allowed by law (Class 3R visible green laser)
  • Compatible with Glock 42 & Glock 43
  • 3 Year Manufacturer Warranty and free Batteries for life

The Crimson Trace is another great light option for your Glock 42 and Glock 43. The Crimson Trace comes equipped with an ultra bright laser (the brightest allowed by law) and a few ergonomic features. The light has easy to use front activation buttons and an automatic activation feature. The crimson makes a holster separately that will fit your gun and light combo, so no more hinting for a compatible holster. Equipped with less lumens than most of the other options, does not mean we should cast this Glock light to the side, especially if this is your EDC firearm. If you are running a smaller Glock we believe it may be too much to have 800 lumens on such a small gun. This light strikes a good balance between lumen output and gun size. This Glock light is a great option for those looking for a quality light from a trust worthy company.

Glock Light Holsters

So you have picked your light, and now you need a holster that fits your light mounted Glock. There are not too many options on the market for holsters that fit with lights due to the fact there are so many different sizes and variations for lights. The best ones we have seen on the market is made by T-Rex Arms and Fobus Tactical.

Glock Light Compatible Ragnarok Holster

light Compatible Ragnarok

The Ragnarok holster was made to be extremely modular, tough, modern, and fast. Made from heavy duty Kydex, this holster is a passive-retention holster, with screws to adjust the retention rate. Being able to fit almost all Glock models ,this is a great holster for anyone who has a light mounted on there gun. T-Rex Arms are one of the smaller companies out there that makes gun accessories, but they are top quality. It’s best to order your holster anytime but holidays, they tend to sell out fairly quickly.

Fobus Tactical Glock Light Holster

Fobus Tactical RBT19

The Fobus Tactical Glock holster is definitely a unique light mounted Glock holster. This specific model fits the Glock 19 but has other options that are compatible with other Glock models. Made of a lightweight polymer construction, so it is not as durable as Kydex but still gets the job done. The best part about this Glock holster is that it will work with pretty much any Glock light you can find. Since the holster has a partial opening it is not restricted to specific light sizes. Being one of the few holsters that are compatible with attached lights, it is very reasonably priced.

Choosing the Best Glock Light (Buyers Guide)

Although we did cover the best Glock lights for the money and overall quality, you still might not have found a match for you, so we will cover how to choose a quality light for your Glock.

Glock Light Sizes

Full size Glock's have a universal rail so it is not hard to find a light that will fit. When it comes to Full size Glock's, there are many options out there, considering anything from Streamlight or Surefire will serve you well. Another aspect we consider is the battery, we tend to like the ones with more popular batteries since they are easier to come by and tend to be cheaper. If you are considering a light that is not as popular, we look at where it’s made and the warranty that comes with the light. If a light maker adds a good warranty you can be pretty certain they stand by their product, and usually anything made in the USA is a good bet.

As for subcompact Glock's such as the Glock 26 and the Glock 43 your choices are limited. One of our favorite subcompact Glock light is the TLR-6 which comes in many sizes for subcompact Glock firearms, and as a plus it has a laser. The TLR-6 has ambidextrous buttons, 100 lumens output, and is extremely light running at 1.270 ounces. One negative thing about this light, is it only has 1 hour of runtime, so make sure you stock up on batteries.

Glock Light Lumen Output

When it comes to brightness, we tend to go for medium to high light output lights. There is a learning curve to high lumen lights (such as wall blinding), but if you practice you can be very affective with a high output light, and can be used affectively outdoors as well. If you are using this light solely for indoor use, you can go with a lower lumen light which will be used only to see what’s in front of you, and won't necessarily blind the perpetrator, but you also won't blind yourself shining it on white walls or mirrors.

Glock Light Durability

The durability of your Glock light is extremely important, mostly because you don't want it to fail when you really need it. The first thing we look at for a Glock light is the material the light is made of. The one’s listed above are mostly made of strong, aircraft-rated aluminum, since it’s lightweight and strong. Another important thing we look for is the ability for the light to be water-resistant. Having a waterproof Glock light allows you to be able to use the light in the elements, such as rain and snow.

Glock Light Ergonomics

The ergonomics of your Glock light is extremely important. Being able to manipulate the light at a moments notice is priceless. With the TLR Glock lights or the Streamlight, it is very easy to switch the light on, off, and strobe with just your index finger, and without looking down at the gun. Making sure you don't have to look down at the gun, is one of the more important criteria we use to find a Glock light.

Glock Light Cost

When it comes to Glock lights, you typically get what you pay for, but that does not mean you have to spend an arm and a leg for a quality light. From the price range around $100 you can find a Glock light that checks most of the boxes, from waterproof, strong material and a great company that backs it. In the $200+ range you can start to get into the professional grade Glock lights, with all the bells and whistles, such as a built-in laser, compact, longer battery life, and light weight. Not only is the cost of the unit important but keep an eye out for the type of batteries they use. If the battery is not widely available, you will be paying extra to replace them and can be hard to find some types. If you do go with a light that has hard to find batteries, you should think about having a small stockpile of them.

Glock Light Installation

Installing a Glock light is pretty straight forward, for the full-size Glock they will have a universal rail that the light slips right over. Every light will be a little different but, usually you won't need any tools to install a Glock light. The lights usually have a small screw you loosen, which enables you to slip the light into the grooves of the Glock, then you tighten the screw and your done. For the subcompact Glock, the process is a little different, where there are a set of a few hex screws that are used to clamp the light to the frame of the gun. The only tools you may need to install your Glock light is a set of allan wrenches, and maybe a flat head to cinch down the light.

Top Glock Light Brands

There are a few companies that lead the weapon mounted light business. Finding a light from one of these companies will be your best bet

surefire logo

Amongst all the weapon light brands Surefire has definitely made a great name for themselves, making quality lights for just about every occasion. Surefire not only has weapon lights, but flashlights, helmet lights, and headlamps as well.

Most Surefire lights are extremely bright, have great ergonomics, and have a wide variety of sizes and specs. It’s safe to say Surefire is one of the best civilian facing weapon light companies.

streamlight logo

Streamlight has been around since 1973, and our favorite brand for a few reasons, they have affordable options and make extremely great quality products.

Streamlight products have no problem lasting in rough conditions, since they are usually built to be waterproof, and have a shell made with aircraft aluminum. Versatile enough to fit most popular striker fire handguns, these lights are a smart choice.

Even if you need a different lighting application, odds are Streamlight has what you are looking for. Headlamps, Safety Rated Lights, Lanterns, Ultra-Violet/Infra-Red are just a few examples of what Streamlight has to offer.

viridian logo

Viridian Weapon Technologies is another great company, but they are most notable for their innovative approach on the products they create. Viridian is responsible for a number of firearm innovations you can view on their website. Designed and built in the USA, Viridian creates products for all sectors (civilian, military, law enforcement).

We are a fan of Viridian products because they are innovating the products we use everyday such as the weapon light mount. Bringing in technology that has not yet been introduced this way before is an exciting feature.

Glock Lights F.A.Q.

After a few thousand rounds at the range the glass gets quite dirty. What's the best way to clean it?

When you are shooting with your light on, you have to worry about build up from the gas expelling from the muzzle, and the glass on your light gets dirty also. The best solvent we have used that gets it cleaned up is simply some rubbing alcohol with a towel. Don't use any kind of abrasive brushes or tools because it's easy to scratch the light lens.

How many lumens is too many?

This is a common question and an age old debate. What we typically do is buy for our rig. If you are running a Glock mini, 800 lumens might be overwhelming and you could easily go with something that has half that. As for something like the Glock 19 or 17, 800 lumens is a good option, as long as you practice with the light. Take note to buy for the size of your gun, the more the light protrudes beyond the muzzle, the dirtier the light will get when you shoot it.

Will the light scratch my gun?

There’s nothing worse than getting your otherwise perfect gun scratched up, but you may not have to worry about that. The Glock lights we listed above are very high-quality and have great engineering behind them. What we found is that as long as you tighten the light adequately so it doesn't move when the recoil hits, you should be able to avoid it getting scratched. On another note, since the Glock has a polymer frame, it doesn't have the same scratch prone tendencies as a metal frame gun.

Final Thoughts

When it comes to choosing the best Glock light for you, pick the one you are most comfortable purchasing at that price range, since all these lights perform so well. This list is dominated by Streamlight but we do stand by there products they make. Comment below what you use and what you think should have made the list.
