Fenix E18R V2.0 Review (1200 Lumens, 16340, USB-C)

Fenix has a new small higher performance EDC with the updated FenixE18R V2.0. This is running a Luminis SST40 and a 1634 battery. Its biggest competitor would be the Olight Baton 3, and I will be using that as a comparison throughout the review. Thanks to Fenix for sending this to me to look at and review, all opinions are my own.

Packaging & Accessories

The packaging here is a nice fully decorated retail-style box. The outside has some of your typical stats on the back. Inside the light is in a plastic tray, but what I really like here is that the accessories underneath are held in place with an extra piece of plastic. While this is minor it really helps to put everything back into the box with ease. If you save boxes and everything that comes with a light like I do this a useful bit of packaging. Accessories include the light itself, preinstalled pocket clip, lanyard, 700mAh Fenix branded battery, USB-A to C charging cable (short), layard, extra orings, port cover, warranty, and manual,


Design & Construction

The E18R V2 is made from 6061 aluminum, and hard anodized in black in a smooth semi-gloss anodizing. The tail is mostly flat, and strong magnetic. It tail stands without an issue despite it only having 2 outer wings. The tailcap as very shallow straight knurls on it for minimal grip.

The body has very fine circular grooves milled into it. They provide a minimal amount of grip but on a light this small I feel like the clip help gives your fingers something to lock on to. The threads on the tail are anodized and inside there is a spring only on the rear of the light. The head is glued onto the body tube, and the clip only attaches in one position but isn’t captured in terms of rotation.

The head has a slightly raised area around the electronic switch. The switch has a metal button cover with LED in the center to give the battery and lockout status. The accent colors here are a rosy copper color that I think is attractive. The USB charging port is opposite the button, and the port cover here is very secure as it has an additional hook to hold it in place.  The lens is plastic TIR with a flat top, with no additional cover to protect it. The light has basically no bezel, what bezel it does have is flat.

Lastly, the markings on this light should be mentioned, they are laser engraved, and nicely aligned. I like that they hid the CE mark, and it contains the typical hot warning near the head. What I hadn’t seen before but think is a decent idea is very small directions under the switch to remind you how to lock and unlock the light.



The primary retention method with the light is the dual direction pocket clip. It’s designed primarily as a lens up carry clip which isnt’ my personal favorite method. When carrying this way it leaves about ½” of light sticking out. The same can be said If you flip it over. The clip is also one of the 3 ways to do lockout on this light if you slide it over so it physically covers the switch. 

You also have the two lanyard attachment points on the rear of the light. In hand it’s pretty small, the body design doesn’t aid much in grip but the clip does when installed giving you a place to lock into.


Size & Weight

I measured the length at 66.64mm, and the diameter at the head at 21.1mm. I measured the weight with the clip and battery installed at 1.9oz. The light is IP68 water rated and impact resistant to 1 meter. In comparison to the Olight Baton 3, the E18R V2 is just slightly longer. 


LED & Beam

The Fenix E18R V2.0 is using the Luminis SST 40 LED in cool white. On my Opple meter, I measured it at 5278K with a 62 CRI. So a fairly neutral tint but a pretty low CRI. There is PWM but it’s extremely fast, I don’t think anyone will notice it. 

The beam profile is pretty typical of a TIR-style optic. A reasonably large hot center with minimal spill and no artifacts. Good for short-range EDC tasks and throws further than you think in the higher output modes when needed.


Outputs & Mode Spacing

For my output measurements I tested on my Texas Ace calibrated PVC lumen tube, it’s not professional measuring equipment but usually a pretty good approximation. Outputs here were very close to Fenix’s claim, the only place I saw a difference was turbo and that was only by 30 lumens or so short. 

Mode spacing here not taking into account Turbo is 4 modes from 1 to 350 lumens. They are well spaced inside this, and I appreciate they included a true 1 lumen moon mode here. Turbo on the other hand is kind of off the charts at 1200 lumens.


Heat & Runtime

For my heat and runtime shots, I used the Li-ion battery the light came with. Turbo stepped down after 1:45 down to the 600-lumen range. The heat peaked around the 6:00 mark at 46C. The light ends up being very stable at about 11 minutes of runtime around the 400-lumen mark and runs out till 42 minutes before seeing a large stepdown and running in moonlight mode out till an hour. 

I also did a runtime test comparing Turbo, High, and Medium modes that you can see in this graph. 



The UI is a little different from many other flashlights, so it might take a few minutes to understand if you’re coming from Olight, Thrunite, Nitecore, Sofirn, and others. To turn it on you have to long press. To increase in modes once on long press and the light will cycle from moonlight mode up through turbo. The light does have memory for all modes except strobe and turbo. If you shut it off in Turbo it will come on again in High next time. There is no shortcut to turbo, you have to incrementally get there. You can access moonlight mode by long pressing from off. If you hold the button too long when turning off the light will also go to strobe. Double pressing is a shortcut to strobe. To turn off you long press again. To lockout, the light double tap when off, same to unlock. You can also unscrew the tail cap slightly or cover the switch with the pocket clip.

Personally, this isn’t my favorite UI, and I would prefer there to be direct access to turbo with a double tap, and strobe is a triple tap. I find myself instead putting the light into strobe when I want turbo. Long pressing to turn off isn’t my personal favorite either.



The light has onboard USB-C charging opposite the e-swtich on the light. I had no issues charging via USB-C to C or PD. I ran all tests with the included Fenix 700mAh branded battery. I tested the capacity of this battery at 685mAh on my Vapcell S4 Plus charger which I reviewed previously. 

Charging from LVP of the battery at 2.973V to full when charging stopped at 4.163V took 1:21:00. Charging speed was right at 1C for most of the charging, and the charging curve looked pretty typical.

The light is capable of running a few different battery types. The manual notes that it can run a standard button top 16340, but may not be able to achieve peak performance. Same with a CR123a which is nonrechargeable. LiFePO4 16340’s are strongly not recommended due to the lower voltage the charging circuit isn’t designed to handle these.

One thing to note is that the battery level indicator is specified to only work with the Fenix branded ARB-L16-700P battery the light comes with.


Final Thoughts

There is a lot to like about the Fenix E18R V2.0. I like the design of the light physically I think it looks pretty good with the bronze-colored accents. There isn’t a ton of grip on the body tube but for me, the clip makes up for that. The tint here doesn’t seem to have any noticeable undesirable green tint. While I tend to like more neutral or warm emitters I understand why they went with cool white here to maximize the number of lumens and because it seems that’s what the segment of the market this light is aimed to prefer and it’s not super blue.

I like that battery here isn’t proprietary, and that it can run on CR123a’s in a pinch but with reduced performance. Another plus is that it uses USB-C for charging instead of a proprietary system.

A few things I wasn’t a fan of either, like UI here with no direct access to turbo, and where strobe is only a double pressor extra long press when turning off. I am not as much of a fan of lens up carry with 1/6th of the light sticking up out of my pocket and the switch being right at the pocket hem of your pants or shorts.

Overall a pretty solid light. If you like Olight but want to try another brand that’s similar but different I think this would be a good place to go. The UI will be a change for sure, but it’s a well-built light with a good beam thanks to the TIR lens and above-average build quality.

Fenix GL19R Review (1200 Lumens, 18350, Tactical WML)

Fenix introduced a new line this year with the high-performance weapon-mounted tactical lights. Today we are looking at the brand new GL19R a midsize pistol mount light, with a TIR style reflector, onboard USB-C charging that runs off of a standard 18350 battery. With the name GL19R, I had to put this one on my Glock 19, it just seems it was meant to be. Thanks to Fenix for sending this preproduction sample to me to look at and review.

Packaging and Accessories

Since this is a pre-production model I don’t have any samples of the retail box or the final accessories. It did come with a 1100mAh Fenix branded but standard flat top 18350 battery, USB-A to C charging cable, as well as two different rail attachment points to fit both Glock and 1913 sized rails. A quick note on the manual, I thought it was kind of interesting they included some basic gun safety instructions that were actually good such as “never point a firearm at something you are not willing to destroy”. 


Construction & Design

The light is made from aluminum and hard anodized in a flat black color. The overall design is similar to what I have seen from other weapon lights, nothing very revolutionary. The front untwists to give access to the battery. It has springs on bother sides, which is good. The front bezel has small crenulations and stands proud of the large TIR Optic. The optic is topped with glass which is great for cleaning and scratch resistance.

I will cover the mount in the section below. The user interface buttons are plastic, with a little texturing. They are hinged at the bottom and the actual button to press is at the top. I like this, as I rest my finger above the trigger on the frame of the handgun.

Labeling on my light is a little strange, there are sections on the head and one on the body that is shiny and it looks almost like they put a sticker or paint to cover up something, then did laser engraving again. I expect this is unique to the preproduction unit I have as they make slight label changes.  I do like that the engraving here is grayer than bright white and the required CE and No Recycling markings are made on the underside where they won’t be seen when mounted. 


Size and Weight

I measured the length at 70mm (not including the buttons) width at 30mm and height at 31mm including the top of the mount. The outside diameter of the head is 25mm. Weight with the battery came in at 3.50 ounces with the battery or 99.2g. The light is impact resistant to 1M and IP68 water-related. 


Mounting Options

As mentioned before the light is designed to be mounted on the rail of a firearm. It came fitted with the aluminum insert for Glock, but a 1913 piece was included. It’s secured with a small Torx screw. The light uses a quick-release system on the right side of the light, with an adjustment screw on the left side. It’s a little different from the system that Olight uses and doesn’t have as much range of motion. Once properly adjusted it does fit snugly but it’s not as easy to switch between firearms without adjustment. Probably not an issue for most people. The lock is pretty easy to actuate, while it does it flush I would prefer a bit more force needed to unlock it, just for extra security. 

As far as holsters, being such a new product I couldn’t find any with a search online and Fenix didn’t have any partners signed up at the product launch, so you will have to turn to the custom holster market if you want a holster for your firearm and this light. That is one of the problems with new companies getting into the market for the first time. 


LED & Beam

The GL19R is running a Luminus SFT40 LED. No official tint is given by Fenix here, but my Opple meter measured it at 5570k, and 62 CRI. The beam mostly spots as you would expect in this application, the TIR reflector helps increase the size of that hotspot and minimize the spill. On Turbo there is almost no PWM according to my Opple meter but there is a decent amount on High as visible from the meter. 

I have a calibrated Lumen Tube now from Texas Ace and this was the first light I put on it for lumen output and later runtimes. Official outputs put Turbo at 1200 lumens, I tested it at 1197 Lumens at 30 seconds, and on High, it’s rated for 350 lumens, I tested it at 339 lumens, so all very close to as advertised. 


Heat & Runtime

In Turbo mode, you can count on that full output for the first 30 seconds, before you see any declines, the decline happens slowly out to 3 minutes, where the light is making about 500 lumens. It holds this for about 50 minutes before a significant stepdown and shutting off right at 1 hour. During this time the hottest I saw was at 43C at the 55-minute mark. The light does have thermal protections at 60C according to the manual but I never saw that high of temp when I tested at room temperature. 

I compared Turbo to High outputs and while High produces quite a bit fewer lumens about 340 lumens, the shape of the curve is a very linear decline out to 2 hours of runtime. In high mode, my meter did measure a decent amount of PWM too. 

There is a low voltage warning on the light with the battery indicator on the left side, it flashes red, but it also reduces the light’s output to only 50 lumens so it’s hard to miss. Fenix does recommend charging the light every 4 months if not used for peak performance. 



UI here is a little different but logical. From off you can press the light to turn it on or off into the mode used last and this will turn it on constantly. If you long-press from off the light will go to momentary if held for more than 1 second. To select your different output mode when press one of the buttons and hold, and then click the other to toggle between High and Turbo and vice versa. Kind of difficult to do while mounted in a tactical situation especially if you follow Fenix’s recommendation that the light only is activated with the non-trigger finger and to use a two-handed grip. To get to the strobe with the light on press and hold either switch for half a second to enter or exit the strobe. This is momentary strobe only, not ideal for a tactical situation with ½ second being kind of a long time to activate. It’s worth noting the light does have a way to lock it if you wish and that memory mode works as long as the battery is installed, when the battery is removed the light goes back to default mode. 



Recharging is accomplished via a USB-C port on the left-hand side of the light. The port is covered with a silicone port cover that fits well. The light is compatible with PD chargers however it does not charge in the PD mode. One thing to note is that the light will not work while charging. 

Using the onboard charging here from LVP at 3.074V, the light reported it was full in 1:44:00 and the cell tested at 4.160V. Max charge rate here was 0.72a during the constant current charge phase, with a small spike before it started to decline. Roughly a 1C charge curve here, good for overall battery longevity. 

LED Indicator on the side servers as both a charging status indicator (Red when charging, green when charged) and as a battery check. Check the manual for what the different colors and blinks mean. 



The Fenix GL19R is a solid offering from a company experienced with tactical lights but new to pistol-mounted lights. The build quality here seems to be good, and the mounting system works pretty well. The rear buttons are certainly better than some brands but it’s hard to beat Shurefire’s toggles in my opinion. I would say it’s as good if not better than the system Olight is using on their similarly sized models. I really like that they are using a standard battery size here, so nothing is proprietary and it will easy to get replacement 18350’s in the future. 

I think the UI here while it works could probably be optimized, the UI here means you have to go into a situation knowing what you want to use, for me that would be high mode, and then bump up to Turbo if I needed it. To do that while easy in theory I find is a little hard to actually reach. I would prefer a quick double or triple tap for turbo, and something similar with strobe. 

Other than the UI side of things I think this is a solid offering. Hopefully, Fenix is able to partner with some holster manufacturers soon and we see some support for that soon.
