What is a 18650 Flashlight?

First things first, let’s establish what these flashlights are, because trust us, they are NOT your typical flashlight. 18650s are typically a lot more powerful and are used in situations where your old run-of-the-mill torch will simply not suffice.

These flashlights are often used in EDC or tactical defense situations. Some of them can be attached to firearms using a specialty Picatinny rail system. This makes them a popular pick for AR owners. While these flashlights are a bit too large for pistol attachments, some slimmer models have started cropping up that can be made to work with pistols.

If you’re not into firearms, that doesn’t necessarily mean that a 18650 flashlight is not for you. They find plenty of uses in camping, exploring, hiking, and more. You can use them at home in the event of a power cut, in the garage, or in the car. They replace your standard flashlight in every way possible.

Using 18650 flashlights without a firearm

As mentioned above, you can successfully use 18650 flashlights when you are unarmed. You don’t need to be a fan of guns in order to find a lot of uses for these flashlights. However, some people don’t know how useful these things are even if you’re unarmed.

18650 flashlights are incredibly bright. This makes for an easy, non-violent way to escape a potential attacker. You can temporarily blind them as you gave away, or you can defend yourself further. If your flashlight is equipped with a strobe function, this helps even more.

Whether you use it as a backup escape route or a tool to attack, a 18650 flashlight can sure come in handy in most situations.

Reasons To Buy & Carry A 18650 Flashlight

Knowing what these flashlights do, what are the reasons most people decide to buy one? If you still haven’t found a use for it in your life, let us talk you through some ways that you can use your flashlight for.

Keep in mind that these torches are a lot brighter than, for example, a smartphone flashlight, so they serve entirely different purposes.

It’s legal to carry in all states

While a 18650 flashlight can be used as a weapon, it’s legal to carry in all the states in the US. It makes for a great addition to your EDC setup and it is easy to transport by simply clipping it onto the belt.

Attack prevention

As mentioned above, a 18650 LED flashlight is a great way to defend yourself against dangers such as home invasion or other types of combat. It’s not a lethal weapon, but it’s capable of temporarily blinding the attacker, and the toothed bevels on the surface of the flashlight can be used as a low-harm weapon.

Remember that in order to properly use the flashlight in combat you will need to learn and practice first.

Blackout protection

Trust us when we say that not many light sources will be as helpful in a blackout as a 18650 flashlight. Whether you’re out in a dark place or your own home has a temporary power cut, a 18650 torch is a sure-fire way to get you out of that situation unscathed.


When the night falls, you can sit by the fire, but you can’t take the fire with you. Fortunately, a 18650 flashlight is powerful enough to light up even the darkest woods.

Things To Consider When Buying the Best 18650 Flashlights

You might think that shopping for a flashlight is the easiest thing in the world. That might be true for some basic models, but for a 18650 flashlight, there are many things for you to keep in mind when you get one. There are also many flashlights on the market that may meet your needs.

In order to make the best possible decision, please review our tips on what to look at when buying a 18650 flashlight.

Shape & design

No matter the intended use, you want your torch to be compact, lightweight, and ergonomic. Fortunately, 18650 meets every single of those criteria. These torches feature a small chassis, a cylindrical shape, but the size shouldn’t fool you — they produce a remarkably powerful light beam that can light up to half a mile or even more.

If you want a pocket flashlight that will fit a standard pistol, you should get a 18650 torch that measures at under 5 inches. These models can usually be clipped onto the belt and often come with their own belt or holster clip.

It’s important to keep a strong grip on your torch, especially if you intend to use it for self-defense purposes. We recommend looking into flashlights that have cross-hatched grips etched into the barrel-frame. Such a grip will provide the best traction when you wear tactical gloves, allowing you to make sure that you won’t drop the torch.

What about home defense? If you want your torch to serve as more than just a guiding light, you need to buy a 18650 flashlight for home defense that has a bevel at the front. The bevel acts as a weapon in dangerous situations.

Lumen output

The Lumen output describes the brightness of the light that your flashlight can produce. When it comes to 18650 flashlights, you should aim for at the very least 1000 Lumen or 1200 Lumens. However, if you’re able to afford a stronger model, you can go as high as 2 000 Lumens.

The torches with a high maximum Lumens count (2 000 Lumens+) are referred to as high-power models. These tools are perfect for close-quarters combat (CQC) because their light is nothing short of blinding. Of course, this applies to the highest setting – they normally have lower light variants, too. You can expect light modes such as high, medium, low, firefly, and more. Firefly & low modes are often rather dim in most tactical flashlights, especially those below 1000 Lumen.

No matter what you plan to use the torch for, remember that generally, the higher Lumen count, the better. More Lumens equals a broader throw of the torch & a brighter light beam.

Build quality & durability

As you’ll most commonly use your flashlight in low-light areas, odds are that you will drop it many times over the years. As such, it’s often better to spend a little more and get yourself a sturdy flashlight.

The most durable tactical flashlights will have a stainless steel chassis or an aluminum chassis and will also have extra reinforcement. It’s also a bonus if the coating is corrosion-resistant.

Water resistance

Just as you want corrosion resistance, you might want to look into the torch’s water resistance rating. If you want to go to the tactical range, hiking, or camping, a water-resistant flashlight will be a lifesaver.

During camping and on your hikes, you will need a made from aircraft grade & hard-anodized, stainless steel, pocket-sized flashlight capable of surviving a rainstorm, snow, and even taking a swim. Most torches have an IPX6 rating or higher, but if you want something totally waterproof, you need to aim for IPX8 rating.

Battery life

All 18650 torches rely on battery power for continuous operation. The best battery type to look for is 18650 lithium-ion. Flashlights with lithium-ion batteries offer the longest battery life of all.

An added benefit of these batteries is that they offer USB-charging capabilities. Some of them offer USB-C compatibility, but most models are compatible with micro-USB chargers. One way or another, this means that you will likely have a rechargeable battery & a long run time.

Extra features

If you really want to get the best bang for your buck, look into picking up a torch that offers even more in terms of extra features.

  • Zoom — Some models of 18650 flashlights offer zoom and focus functionality.
  • Light beam expansion — You may be able to twist the head of the torch, adjusting light beam size.
  • Magnetic positioning base — A magnetic base will allow you to light up the room while keeping your hands free. This is a feature often used around cars or workshops.
