Things to Consider When Buying the Best 18650 Flashlight

Overall, different people have different opinions regarding the best 18650 flashlight money can buy. That being said, if you wish to get your money’s worth, then it’s strongly recommended that you keep in mind the following considerations.

Light Output

Since people rely on flashlights for illumination, it’s obvious that light output would be one of the top concerns. Nowadays, the output of flashlights is measured in lumens. As the lumen rating increases, the output increases accordingly.

To determine the ideal output for your flashlight, you must think about its intended purpose.

For instance, you don’t need a blindingly bright flashlight just to read books. However, if you frequently have to navigate dimly-lit spaces, then we recommend prioritizing high lumen models.

AA flashlights are a good example if you’re looking for flashlights that are bright and long-lasting.


Generally speaking, it’s unwise to handle flashlights roughly, but you should nonetheless give durability some thoughts before committing to a purchase.

The last thing you want to spend your money on is fragile flashlights that break apart after the lightest hits.

Thus, while assessing models on the market, it’s suggested that you check out the design, material, and so on. Additionally, to reach an objective conclusion, you need to look at the reviews of fellow users.

For the toughest flashlight options, you can also consider getting durable police flashlights that are meant to withstand all kinds of impact and damage.

Ease of Use

It’s definitely frustrating to get stuck in the dark with an overly complex flashlight that refuses to turn on no matter what you do. As a result, it’s widely advised that you pay attention to ease of use and save yourself a headache.

If you come to like a particular flashlight, refrain from picking it up until you know for certain that you could master its control. Flashlights packed with features would only provide negligible values if complicated controls prevent them from being put to good use.

Size and Weight

When it comes to size and weight, it’s all about individual liking.

Some prefer compact, lightweight flashlights, while others opt to purchase sizable models.

Small flashlights, like keychain flashlights, should have top-notch portability in the typical case, but big ones usually boast superior runtime on average.

Hence, to grab a fitting flashlight for you, it’s essential that you consider the way you store your flashlight and how you wield it. This should help you narrow down your shortlist.


Flashlights come at various price ranges, so suitable models exist for virtually every shopping budget.

Unless you have specific demands, there is no need to empty your wallet to buy an expensive premium-grade flashlight.

Today’s market contains a wide range of quality models that come at reasonable prices.

However, since the price is still linked to performance, you should steer clear of dirt-cheap flashlights as they often utilize corner-cutting to keep the price low.

Well-Regarded Brands for 18650 Flashlights

Technically, you don’t have to limit your choices to particular manufacturers of flashlights. If you come across a flashlight that meets your requirements, feel free to buy it without bothering about its brands.

But in case you wish to stay on the safe side, it won’t be a bad idea to get your flashlight from one of the brands down below.


By constantly updating its facilities and production techniques, Fenix builds solid flashlights that never displease.

Is It Necessary to Invest in a Battery Charger?

A couple of 18650 flashlights have integrated chargers that allow users to charge the battery without taking them out. If you happen to buy a model that lacks such a feature, it would be wise to pick up a dedicated battery charger as soon as you can.

By keeping a good charger around, it’s going to be a breeze to keep your flashlight supplied with charged batteries.
