Are you in a Hurry? Or you don’t feel like reading? We recommend the GearLight M10 LED Tactical Flashlight as Our Pick.

 

In this article, we’re going to review the following AAA Flashlight.

 

What Exactly is a 18650 Flashlight?

There is no doubt that there are huge varieties of flashlights to buy on the market. What makes a 18650 flashlight different is its battery. ‘18650’ is a battery-term indicating a lithium-ion battery with a size of 18mm diameter by 65mm length in a cylindrical shape. While many people opt for your average AAA-battery flashlight, a single 18650 battery gives out the same power as three disposables, can be easily recharged, and provides brighter light for a longer period.
 

Why a 18650 Flashlight is the Best Choice

A 18650 flashlight is a great choice for every-day use or for outdoor enthusiasts/survivalists who are prepared for every and any kind of situation. Because of its lithium-ion battery, users enjoy a brighter light for longer. When the battery does eventually run out, it is easily recharged. 18650 flashlights are known for their functionality and durability. For people on the move, search and rescuers, anyone who enjoys outdoor activities, or even for professionals to use at work, the single 18650 battery is more powerful than 3 or 4 AAAs. It will also put out higher volts at 3.7, facilitating three times the amount of runtime. Its length is the same as two CR123A batteries so it can easily be interchanged. 
 
Understanding the merits of the 18650 battery is a good place to start, but you will also need to understand some key flashlight features like run time, bulb type, lumens, application, beam type, and budget to help guide you in your pursuit of finding the best 18650 flashlights.
 

Run Time

Run time refers to the time it takes for a flashlight to drop its power to 10 percent of its rated output. Most often, the run time is determined by which light mode the light is using. Flashlights that offer high run times, even while on the brighter mode, are the better-quality ones.
 

Bulb Types

The main preference for bulbs currently is LEDs. They have longer lifespans, and they are more energy-efficient than their incandescent-bulb counterparts.
 

Lumens

Put simply,‘Lumens’ is a measure of light output and also refers to the light’s intensity level when used in the flashlight’s highest setting. Lumens designations vary across a huge spectrum from 20 to 3,500. A flashlight with a high lumens equals a brighter light.
 

Throw

A flashlight’s ‘throw’ refers to how far its light beam travels ahead before it lessens. The beam distance can vary depending on which brightness mode the light is using. 
 
The throw is an important factor to consider as it reflects how the light will be used. If you are looking for a light for search-and-rescue missions, you will want one with a long reach and a narrow beam. Floodlights are best for hiking and camping purposes for a wide light displacement, while flashlights with different color modes are ideal for hunters.
 

Beam Type

Most flashlights have three main beam types: spot, flood, and adjustable. Flood beams are single beams most commonly chosen for basic tasks like hiking or camping. Spotlight is a condensed beam which is good for illuminating far distances. Adjustment allows the owner to change the light between ‘spot’ and ‘flood’.
 

Budget

When it comes to pricing, expensive doesn’t always equal better. Durable and high-lumen lights with 18650 batteries make a good choice as many flashlights that take AAs, AAAs, or specialty batteries make it harder and more expensive to find replacement batteries.
 
Now that you are familiar with some of the main features and differences between flashlight types and models, we’re ready to move on to 5 top recommendations for the best 18650 flashlight.
