What is The Best 18650 flashlight?

While rechargeable models with different battery types exist, the 18650 li-ion battery remains a firm favourite among flashlight enthusiasts.

Below, we look more closely about why this particular battery class is considered so sufficient, as well as at some of the best models available.

Why Worry About a Flashlight – Surely any will do?

A good, reliable flashlight is a must. A good flashlight can range anywhere from ‘convenience’ to ‘lifesaver’ depending on circumstances. It can attract attention, help you reorient yourself or avoid obstacles, or blind an attacker to allow for your escape.

Strobe models can be very disorientating to an attacker, while low-light, eco-friendly options will allow you to look something up I a book without destroying your night vision. Regardless of what your primary purpose is for your flashlight, getting a robust and reliable tool is a must.

While you can still buy battery reliant models, most modern flashlights are turning to rechargables as the best technology available for convenience and reliability. The 18650 battery is widely regarded as one of the best rechargeable batteries to use in a flashlight.

Many compartments are versatile, as they will also take two smaller batteries, but having the one single battery removes a lot of the risk of multi-battery setups. This particular battery offers a fantastic blend of output, long length of use and stable light.

Of course, any flashlight, no matter how carefully treated, is going to hit the ground every now and again. It’s a simple fact of life. This is why it’s vital that you search out a robust design for your torch.

No-skid protection, anti-abrasive coatings and more can help extend the life of your flashlight as well as keep it looking good. The torch should be sealed as much as possible to prevent splitting open.

Remember that 18650 batteries ae not small- you will not get one that will work on a keychain, for example. All the same, there is a large variety in sizing for you to choose from, and it’s critical you make sure you get a size that’s suitable to your needs and comfortable to carry.

Light output is a concern, with nothing below 100 lumens offering any kind of defensive advantage, and will need to be carefully considered for your needs.

You will also need to give a little thought to the style of beam you would prefer- from floodlights to narrow focus beams, there is a torch for almost any purpose. Many good flashlights will offer several light settings, including the attention attracting [if slightly disorientating] strobe effect.

While having several lighting function modes is not absolutely critical, it may well be a feature you need. A high beam can be useful at sunset/sunrise when light becomes murky, but may be overkill for a confined space at night. What particular purpose your torch needs to serve depends on you.

While a 1 18650 battery torch has a lot of advantages when it comes to the prevention of connection issues, you can connect these powerful batteries in serial for a torch that provides a much more intense lighting.

These torches will, of course, be heavier and larger than a single battery model, but provide more light for longer.
