Fenix E18R Flashlight Review
The Fenix E18R is a tiny little flashlight that runs on a single 16340 cell. It uses a Cree XP-L HI emitter, and has an indicating switch!
Official Specs and Features
Here’s a link to the Fenix E18R Flashlight product page.
Just one version.
Price and Coupon
This one’s $65, but doesn’t look to be in stock on the official site. It is in stock on amazon. Buying from amazon will help support my site, and I will greatly appreciate it!
This is a nice little ‘complete package’ light. The battery indicator in the switch is nice, and I like the clickiness. Also of note is that this isn’t one of those spongy mashy buttons – another nice thing. All in all I’m satisfied with the light, but I wish it was just a little shorter.

Lots of stuff!

Package and Manual
The E18R comes in a flip-open display box with the great colors of Fenix (black and orange).
The light and goods are in a plastic tray.
Here’s the manual. There’s a decent UI graphic, and also a graphic of the runtimes on all modes (which might be a little misleading, if you don’t look at the timescale).
Build Quality and Disassembly
I have no major issues with the build quality of the E18R. A minor complaint would be the logo being screen printed over the grip on the body – it ends up looking faded. Not a performance issue, though.
Another minor issue is that the button and the charge port are quite similar. They’re distinguishable by feel, but still similar enough that if you don’t use this light often or it isn’t your main light or whatever, it might be a little difficult to get accustomed to. Fortunately, nothing about the charge port pushes, so you won’t mess up anything; you might just end up hunting for the switch.
The charge port is larger, flatter, and has a nub in the center.
Here are the guts, as far as I got to see them. There’s a magnet that can be removed, in the tailcap. The head doesn’t have a spring but has a brass button, and brass contact for the negative terminal, too (contact which is made through the body tube).
The bezel is press-fit in much like many of the smaller Olights. This bezel won’t be easy to remove, but it’s press-fit ON not IN, so it’s probably possible.
Size and Comps
Length: 2.4” (60mm)
Diameter: 0.8” (20mm)
Head: 0.8” (21mm)
Weight: 1.17 oz. (33.3g) excluding battery.
Much smaller than the Convoy S2+ of course.
Not pictured, but it’s also a few mm shorter than the recently reviewed (and otherwise extremely similar) Olight S1R II Baton.
Retention and Carry
Likely the primary means to carry this light will be the pocket clip. It’s a friction clip, with no holes (which are often used for lanyard attachment). The clip is free to rotate around the light (ie not a fixed position) which is another thing that could allow confusion with the switch and the charge port. A fixed clip gives a good target.
The clip works quite well. It has a big mouth and a deep shoulder, so it fits on jeans or thicker pants, too.
Another option for carry is the lanyard, which only attaches through a hole in the tailcap. The hole is generously sized.
And finally, there’s a magnet in the tailcap. It’s strong enough to hold the light in a horizontal position.
Power and Runtime
The E18R is powered by a single 16340. Fenix includes one in the package – a Fenix branded 700mAh cell. It’s a regular old 16340 – not proprietary. It is a button top. I have a flat top unprotected 16340 floating around my house somewhere (um… yikes?) but I can’t lay my hands on it to test if flat-top cells will work. I do not think the will, just based on the setup of the positive terminal inside the light. I’d probably lean toward just using the included cell or another button top.
Here’s a test on Turbo. The output doesn’t quite last 30 seconds and begins a heavy decline to around 320 lumens. By 1 minute, the light has settled on its stepdown, and is very stable from there. The light never properly shuts off, and in testing with the bench power, does not seem to have low voltage protection. The included cell has a protection circuit, so undervoltage shouldn’t be an issue, with the included cell. There’s also a low voltage warning in the switch around 3V – the switch flashes red. Interestingly, the switch warning fades as the voltage decreases, but the main emitter output is very stable all the way to [cell death]. The claimed runtime for this mode is 45 minutes, which about matches the stepdown from 325 lumens.
The high output is very stable for most of the claimed runtime of 2h35m.
This is a charging version of the light. The charge is achieved through a connector in the head, exactly opposite the switch.
A cable is included: USB to proprietary magnetic. The parts snap together easily and stay snugly enough. The cable connector has a charge indicator – Green means complete (or ‘not being used’) and red means “charging is ongoing.”
Here’s a charge time test. Charging in the CC phase is around 0.85A (reasonable if a little high for a 16340). The CV phase seems to just trail off into nothing – it takes quite a while for the charge system to actually finish the charge cycle.
User Interface and Operation
There’s one switch on the E18R. It’s a side e-switch, with an indicator right in the middle. The switch cover is a nice hard plastic, positively clicky with no wobble, and probably less than 1mm of travel. It’s a very nice switch.
The UI isn’t extremely complicated, but it has a fairly nice set of features.
Here’s a UI table! (Spoiler, the UI is just like the E16 UI!)
|Off||Hold (0.5s)||On (Mode memory)|
|On||Click||Mode advance (LMHT)|
|Strobe||Click||On (Mode memory)|
It’s the double click for lockout that will get most users (me included). Also there’s no shortcut to any mode (unfortunate!!)
^ Battery check, as follows:
Green constant on: saturated (100% – 85%)
Green flashes: sufficient (85% – 50%)
Red constant on: poor (50% – 25%)
Red flashes: critical (25% – 1%)
Modes and Currents

LED and Beam
The emitter Fenix has put in this light is a Cree XP-L HI. Fenix doesn’t state the Kelvin, but I’d estimate it at around 5000K. It’s not nearly as warm as the Fenix E16 (which I really liked because it’s exceptionally warm). The optic used in this TIR light is also the same as the E16.
I really like this optic. There’s very little spill and more of a spot than some more familiar optics.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
In-person, the light looks much whiter than pictured above.
Random Comparisons and Competitive Options….
Here’s a relevantly filtered page on parametrek.com. There aren’t that many lights with XP-L HI in the 16340 format, which also offer integrated charging. And among those, some include lights with cells that have integrated charging (which I don’t really count in this category). So the E18r is a great (ie the only) light in this category with all these features, so it’s worth considering.
What I like
- I love the optic Fenix uses in these lights
- Onboard charging is good (at least in the CC phase, but a little draggy in the CV phase).
- Small for a 16340 light with on-board charging
- On-board charging doesn’t require a proprietary cell
What I don’t like
- Proprietary charge cable
- Charge port and switch too similar, and hard to feel the difference (without looking)
- This light was provided by Fenix for review. I was not paid to write this review.

Thanks for the review, just ordered one.
Cool, hope you enjoy it!

Hi. Great review, as always.
I also have a question, how do you measure lumens? Do you have any equipment for it?
Thanks! I have a standard hobbyist “lumen tube” made out of PVC and hope.

I know this review is old by this point, but did you happen to notice what type of (exposed) lens the E18R has? Is the plastic optic exposed to wear & tear or is it behind a glass lens? Thanks.
Without taking it apart (and … actually… finding it amongst all these boxes in my house)… it’s hard to say. I can say that the E16, which is similar, and I can put my hands on, feels more solid than just a plastic optic. So I’m going to guess probably a glass lens.
Thanks for that.
Are you satisfied with how the E16 has held up over the years since you reviewed it?
Absolutely love the E16. To be fair I can’t make all that fair of a claim on “how it’s held up” since it’s in a rotation of [don’t tell my wife how] many flashlights.
Rather late to the party but I need to ask other E18R owners whether their charging magnetic cap turns green halfway and roughly 30 sec later turns red again and supposedly keeps charging. Beside that mine seems to be able to hold the turbo for ~50sec when fully charged and then steps down. Total turbo usage with each full charge is ~2 minutes. Then this tiny torch refuses to either maintain turbo or go into turbo in general and instead completely removes Turbo level from the queue.
