The Best 18650 Lights in 2019

The 18650 lithium-ion battery is one of the most popular battery form factors in production. Its size and features make it ideal for electronic applications, like laptop and electronic car batteries, and even portable battery chargers. Thanks to advancements in both battery and flashlight tech it's developed into one of the best formats for an EDC light as we've seen in releases the past few years.

An 18650 (named for its 18 mm diameter, 65 mm length, and cylindrical shape) battery offers higher voltage, bigger capacity, and reusability, making it an ideal power source for flashlights. Modern 18650 lights push upwards of 3000 lumens in your pocket, more options for high color rendering, runtimes measured in weeks and months (yes, months), and no longer having to buy disposable batteries or chargers which is always good for the environment.

Below we've rounded up 10 of the best 18650 flashlights available so far this 2019. They're lights that make full use of the battery's capabilities but remain compact enough for everyday carry.

The SureFire Fury IntelliBeam packs an impressive 1,500-lumen max output when combined with an 18650 battery.

I don't understand the review information. For the Fenix TK22UE it says there are 13 reviews with an average of about 3 stars out of 5. If you click on "13 reviews," it's a hyperlink that takes you to an Amazon page for the product, but on that page there are no reviews of the product. So where are these 13 reviews that you are referencing?
Hey raquetman, appreciate the feedback. Just to clarify, the "13" is what we put as default when something a) doesn't have reviews yet on Amazon, and b) not yet in our internal database, both because it's usually something completely brand new like that new Fenix. Down the line we're hoping this can automatically pull from either of those sources, but right now it just has to be "not zero." For the stars and price, that's something we determine ourselves on the editorial side and generally factors in the overall product value, how it compares with the others on the list, etc., and may not exactly line up with Amazon reviews.

Hope that clears stuff up!
For discussion purposes, the Acebeam is just under 3,000 lumens IF you are telling me the Emisar D4 only comes as 3,000. The D4V2 is 4,200 ansi lumens, and nearly 5,300 lumens at turn on. Other LED options are no longer much less than that, and the quick link did not say lumen output.
