What is an 18650 Flashlight?

There are various models available and they all seem the same, right? 

Well, all flashlights are not the same as they have different makes, builds, and batteries. For instance, 18650 flashlights have lithium batteries in them, which are rechargeable. 

These flashlights are three times more powerful than ordinary AA batteries. With the dimensions of 18 mm by 65 mm, 18650 flashlights have a greater lighting capacity. The display is more powerful than usual flashlights and the frame stays compact, too. 

Such flashlights are also better than others because of their amazing recharging ability. You can recharge them more than 500 times to enjoy smooth functioning. 

Are All 18650 Flashlights the Same?

No, all of these are not the same.

They come in different sizes and shapes, while still serving the same purpose of providing light. All of the 18650 flashlights have one other thing in common, and that is the use of lithium-ion batteries. But these batteries have a diverse range of sizes too.

Moreover, all of them come with rechargeable batteries, but their range and display are not the same. They vary from manufacturer to manufacturer, and even models within the range of a brand have differences. 

Hence, all such models are not the same, as they have many external and internal variations. 

How to Choose an 18650 Flashlight

Choosing the right unit can be hard. But it is easeir if you know what to look for. So, here are some features to help you choose the right 18650 flashlight.

Size

The size of the flashlight is the first thing you'll notice. It has to be perfect so you can carry it with ease. If the flashlight is large or weighs more, it is going to tire you out. This then makes other tasks more difficult, so choose one which has a moderate size.

Brightness Level

Since the purpose of an 18650 flashlight is to provide light, it must do so in the right manner. These flashlights offer a brighter light than other cadmium battery units. They have different levels of voltage provision, so you need to consider the brightness level, too.

Battery Life

In emergency situations, you cannot keep stopping to recharge your flashlight, can you? This means you need a model with a longer battery life. It should be so good that you can use it for hours without worrying. So, consider the battery life, too while choosing an 18650 flashlight.
