With the many 18650 flashlights, you might get confused as to which one to get for yourself. Below are the things that you should consider when purchasing your 18650 flashlights.


The lumens is the light output’s measurement and one that refers to the light’s intensity when it is on its brightest setting. The lumen can vary from 20 lumens, which is perfect when you’re just reading a book at night, or a maximum of 3500 lumens or even higher, which you can use to protect yourself when you’re being attacked. The lumens will depend on the purpose of the flashlight.

The distance of the beam will depend on the brightness mode that you’re using. But always make sure that the flashlight has at least one single setting that can provide you with enough throw when needed.
