While durability and reliability are important to look for when choosing the best 18650 light, so are a few other things. The current 18650 flashlights are some of the brightest flashlights ever made, with that said you are going to give up a little on portability due to the size of the battery.

These are not keychain flashlights. When looking through the 18650 flashlight reviews you will want to pay attention to how much power and features the flashlights have, as well as what kind of light they are using.

With the best single 18650 flashlights, you are not going to have as much power as you will with multiple 18650 lights because more batteries mean more power. However, each style still has its uses. When looking at 18650 lights look for one that uses the current generation of LEDs rather than an older LED.

Why Choose 18650?

With all of the different types of batteries out there for flashlights, you might be wondering why you should choose the 18650 over something else like the CR123A. One of the best reasons we can think of is that the 18650 battery is a Li-Ion rechargeable battery rather than a single-use, primary battery and with the right connection, you can easily charge them while you are on the go.

Not only that, but a single 18650 battery is as powerful as 3 to 4 AA battery because of the higher voltage. The 3.7 volts put out by the 18650 provides you with about three times the amount of watt-hours for the same capacity. If you opt for a high capacity 18650, it can be almost 4 times as powerful as standard AA batteries.

Another reason to opt for the 18650 is that it is the same length as 2 x CR123A batteries, which makes it easy to interchange. 18650 batteries have a great size to capacity ratio, and they have a high discharge and high capacity rate making them superior to similar-sized batteries.

Favorite 18650 Batteries and Chargers

Something else to consider is the best 18650 battery for flashlights. As with other types of batteries, you are going to run across numerous manufacturers, but they do not all have the same quality.

When it comes to the best 18650 battery for flashlights you are going to want to stick with batteries that are built around the Samsung 35E. Some people like buying unprotected Samsung 35E batteries trying to save a little money but we prefer the protected batteries. The most accessible 18650 battery that fits what we like is the Nitecore NL1835HP protected top button batteries, which are made specifically for flashlights.

Knowing the best battery to use is one thing, but what about when those batteries need to be charged. These Li-Ion batteries aren’t cheap, so the last thing you want to do is destroy them by using a horrible charger.

In all of the chargers that we have looked at, we feel that the best is the Xtar VC2 Plus Li-ion battery chargers. Not only is it one of the most advanced chargers, but it is also available for a great price and comes with a USB connection that allows you t use the charger as a battery pack.

The Emisar D18 is the newest addition to the legacy that Emisar is building in the flashlight industry. The first thing you need to know is the light is powered by three 18650 batteries, but you can only use unprotected batteries. Protected batteries are not compatible with the light and the only batteries guaranteed to work are a select few that are listed in the specifications of the light.

The Emisar D18 uses 18 SST-20 LEDs that are available in a variety of options including cool white, natural white, warm white 95 CRI and neutral white 95 CRI. The lumen output ranges from a maximum of 10,000 up to 14,000 based on which LED option is selected. The 95 CRI option provides a lower lumen output.

The Emisar D18 offers a ramping interface that allows users to select just the right amount of light needed. The D18 uses firmware called Anduril, which was written by a BLF member and offers a smooth ramping. The interface includes special or fun modes including strobe, lockout, momentary on, and muggle mode. The user interface also allows you to change from a ramping mode to a 6 step output mode.

Features included with the Emisar D18 include low voltage protection and thermal regulation.
