18650 Flashlight – Buyer’s Guide

In order to prevent wasting your hard-earned money on a device that doesn’t really meet your needs, you should decide what exactly matters for you before you start shopping. When looking for a reliable 18650 flashlight, you should consider the following factors:

  • Size.
    A flashlight must be easy to carry around in your pocket or bag, so take note of the device’s measurements (a keychain model is the smallest). Consider its weight, especially if a child will be carrying the piece. The vast majority of 18650 LED torches are tiny and easily fit into your pocket.
  • Light output.
    This is the most important characteristic of a flashlight regardless of whether you need the device for self-defense or simply for finding a keyhole in the dark. If self-defense is your primary concern, you’ll need a torch with over 100 lumens max output as it can temporarily blind an attacker (read our brightest flashlight article to learn about stronger options).
  • Durability.
    A good 18650 flashlight should be waterproof and shock-resistant. It doesn’t matter whether you are going to take it with you when you go hiking or just keep it in your car for an emergency. These devices have a tendency to fall and roll around quite a bit, so protection from impact is a must, and water protection is a useful bonus in case you ever need to look for something outside while it’s raining. The best 18650 flashlights are made of aircraft grade aluminum for increased durability.
  • Modes.
    A really good 18650 flashlight should offer several function modes so that you can adjust the light output to fit different situations. Versatility is good for this particular feature, but there is no need to look for a device that offers 20 different settings. In the vast majority of cases, people only need about 5, including SOS mode, distance, wide coverage, and varied beam intensity (high, low, medium).

#1: SOLARAY Pro ZX-1

However, it does meet the requirements a device of this class should, and if you are looking for a brighter device, you might consider buying an LED torch with a higher maximum lumen output.
