These flashlights are powered by 18650 batteries and will never let you down. In just a few moments, we will share our top picks for the best 18650 flashlights that money can buy. But, before that let us tell you why these flashlights powered by 18650 batteries stand out from the crowd.

At a Glance: Our Choices for The 10 Best 18650 Flashlights

Click on one of the links to go directly to our overview, opinion, and features of each flashlight.

Why You Should Buy 18650 Flashlights?

Protection: Most 18650 batteries that power these handy flashlights come in protected forms. These batteries are preferred over unprotected ones, as they can protect against overcharge, short circuits, a surge in temperatures, and even over-discharge. While much cheaper in price, unprotected batteries fail to offer these features and can damage your flashlight.

Last Longer: Flashlights powered by 18650 batteries are more reliable and last longer thanks to the batteries used in them. Like most rechargeable batteries, even 18650 batteries have a rating which is measured in mAH – milliAmpere hour. This rating serves as a way to measure how much current your batteries will discharge per hour.

For instance, a 2400 mAH battery can maintain a 2400 milliAmp draw an hour before it drops to a discharged voltage level. 18650 batteries are available in varying mAH ratings. And, while this rating doesn’t directly indicate how long the battery will last, you can rest assured that these high drain batteries that have low mAH ratings do last a long time.

Users claim that on normal use, the cycle life of 18650 batteries is up to 500 times more than regular batteries, which means your flashlight will not need a frequent change of batteries.

Better brightness: Since 18650 batteries have a much higher voltage than their counterparts such as nickel-cadmium and nickel metal hydride batteries, the flashlight will emit bright light. You can depend on 18650 flashlights to guide your way, even in pitch dark.

Rechargeable: Yet another selling point of 18650 batteries is that you can recharge them instead of having to dispose of them after use. When your flashlight runs out of charge, simply pop out the battery, plug it into the charger, recharge them and viola your flashlight is ready to use again!

Economical: Since 18650 flashlights use 28650 batteries that can be recharged, they are more viable and are a lot more economical in the long run. Invest in a backup set of batteries and keep them charged at all times. When you run out of juice, simply swap the batteries and you will have light again.

Flashlights are undoubtedly indispensable tools, if you are someone who loves camping. However, if you use yours with alkaline batteries, it may run out right when you need it most.

However, when you invest in a 18650 flashlight and have 18650 batteries, you can be sure you will have a strong beam anywhere anytime. These battery-flashlight combinations aren’t just powerful and consistent, but also take just a few hours to charge completely.

Now, those were a few pros of 18650 flashlights. Let us now review some of the best brands on the market.

This flashlight measures less than 5.51″ but can put out a light of about 1000 lumen. Its beam distance is quite impressive at 656 feet. The FX-PD35TAC can be run on a single 18650 battery or two CR123A batteries.

# of Batteries: One
Battery Duration: 74 h (Very low)

Whether you are out camping, fun hunting, or even on a wilderness hike, you must pack a few important accessories such as a lighter, compass, ammo, binoculars, and a reliable flashlight.

Many first time buyers find it hard to find the right flashlight. If you are on the lookout for a great EDC flashlight, your search ends with the ThruNite TN12. This is a flashlight that is engineered for mobility; it is lightweight, can be easily carried in your pocket or backpack and has an added lanyard.

The ThruNite TN12 EDC LED Flashlight has a rugged design with a thick light head, which is optimized for use in rough terrains. It is made from aircraft grade aluminum and can reach up to 1050 Lumens when set in Max mode and 800 Lumens in Strobe Mode.

It can also be used as a tactical flashlight with the flick of its tail-switch. By pressing the side switch you can cycle between firefly, low, medium, high, and max modes with ease.


Upon use, we found the ThruNite TN12 a good choice for a flashlight. We liked that the flashlight could provide both Cool White and Neutral White light. However, the Neutral White light output was about 20% less than the output in Cool white mode. We found the flashlight easy to use, even with one hand. On half-pressing the tail switch, you can activate light momentarily.

Upon clicking the switch, the flashlight turns on, another click or press and the flashlight is off. Unlike most flashlights, ThruNite comes bundled with a number of accessories. The pack contains O-rings that will keep your flashlight waterproof, a handy stainless steel pocket clip to attach your TN12 to your pocket or belt, a holster to protect it, and a lanyard too.

We found that the LED head gets warm to touch with constant use, but it is not a serious problem and can be lived with. This is by far the best flashlight on the market for under $50.

Water Resistant: IPX8

(+) Has a charging port
(+) Lasts for hours on a single charge
(+) Turbo mode is extremely bright
(-) Light sometimes doesn’t function in very cold temperatures
(-) Exposed contacts for the charging system
(-) Holster is too large for the flashlight


An Amazon bestseller, the Olight S30R Baton III is a flashlight that delivers what it claims. This third generation Olight S30R Baton flashlight comes with a Cree XM-L2 LED and can deliver a powerful maximum output of 1050 Lumens. It measures just 4.49”, and weighs under 4 ounces even after slipping in the battery, making it ideal for every day carry.

The Olight S30R Baton III utilizes an aluminum reflector that delivers an improved beam focus for close and medium range illumination. The reflector is paired with a hardened glass lens that allows 99% light transmission rate. That is not all, the Olight S30R Baton III low power indicator that nests under the side switch and glows red when the voltage dips.


Just like its predecessors, the Olight S30R Baton III is a flashlight you can depend upon. We found its build, sturdy, and durable. We also liked that the flashlight has a charging port that is compatible with Olight magnetic charging cables that however need to be bought separately, but are certainly handy for quick charging.

Yet another feature we liked about the flashlight is that you can double-click to get direct access to turbo mode. One of the few caveats of this otherwise good flashlight is that its exterior houses exposed contacts for charging, which could make it more prone to shorting.

However, this isn’t a huge concern if you are careful. The latest version of the S30R Baton is smaller, brighter, faster to charge, and more efficient too. 5 intensity modes plus strobe, magnetic tail, timer function, low battery indicator, and lockout mode make this a great torch to carry and wins our thumbs up.

The flashlight’s copper plated, chromium circuitry makes way for better heat dissipating and performance.

The ThruNite TN32 weight a mere 650 grams, is easy to carry and ideal for tactical and search purposes. The flashlight needs 3×18650 batteries and has an impressive beam distance of 1043 Meters. The ThruNite TN 32 also features mechanical reversed polarity protection design that ensures you always slot the batteries the right way.


Specially designed for self-defense, military, law Enforcement, hunting, search & rescue and outdoorsy activities, the ThruNite TN32 is a truly incredible flashlight. We found that though it doesn’t have a wide beam profile that can illuminate vast areas, its narrow beam profile is wide enough for most activities. We could put daylight at the other end of over 300 yards, no matter which direction we pointed it.

The flashlight has a simple user interface and can go from standby mode to turbo, strobe or any of the lower modes with a quick flick. To sum it up, the build quality, UI and Lumens OTF – for the price – is simply outstanding! Even with all those amazing bonuses because of the tax cuts being dished out!

The maximum output of this flashlight is 944 Lumens. The low setting produces 37 Lumens while the medium setting can deliver 479 Lumens. The beam produced by the Pelican 7600 has a generous spill beam and uses a textured reflector so as to throw a flood beam minus hard edges.


The Pelican 7600 is rugged, it is stylish, and is a poignant buy. Upon use, we found that the beam is consistent in brightness and has no hot spots, while also being concentric to the body of the light. Both the LED emitters fire through the same single reflector. To our surprise, we found that this flashlight is also fully submersible despite having a rotating ring switch.

We also found the size perfect, as it can be easily stuffed under the arms when not in use. The only flip side is that flashlight takes forever to charge. However, the company has a workaround for this – USB charging and an adapter that can store additional batteries. In short, the Pelican 7600 is a flashlight that can be sworn in any time.
