Fenix 15th Anniversary AAA Flashlight Review

Fenix 15th Anniversary AAA Flashlight Review

The Fenix 15th Anniversary AAA flashlight is one I’ve had bouncing around for a while.  Why not post up some photos (and a bit of testing.)

Official Specs and Features

Here’s a link to a Fenix 15th Anniversary AAA product page.  The light is no longer available, but shop Fenix-Store.com for the latest and greatest.


There is just this one version.

Price of the Fenix 15th Anniversary AAA

This light had an MSRP of $78, but I think the street price was more like $49.95.

Stay tuned to Fenix-Store.com for upcoming Fenix lights!

Short Review

Alright, it’s a twisty.  You probably know I don’t love twisties.  But this one is quite neat with the copper sleeve (sleeve?) and anniversary branding.  For those reasons, I have really enjoyed this light!  Of course, XP-E2 is a bit dated….

^ Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

What’s Included

what's included

  • Fenix 15th Anniversary AAA
  • Primary AAA cell
  • Lanyard
  • Spare o-ring
  • Papers (probably originally a manual, but I’ve lost that)


The phoenix is a long-lived, immortal bird associated with Greek mythology (with analogs in many cultures) that cyclically regenerates or is otherwise born again. Associated with the sun, a phoenix obtains new life by arising from the ashes of its predecessor. Some legends say it dies in a show of flames and combustion, others that it simply dies and decomposes before being born again. [1]

Package and Manual

No manual is included, but I think the back of the box probably covers most of the info.  Also inside this box (which is really a sleeve) is a plastic case suitable for storage and even display of the Fenix 15th Anniversary AAA.  Sorry, I lack a good photo of that one.

Build Quality and Disassembly

feature photo

I might have said elsewhere that the body is copper.  I don’t actually know that… Fenix calls it “rose gold plating” and it doesn’t smell like copper.  It very much feels like copper though and looks like copper.

Fenix also doesn’t state the body material, but I’m nearly certain that the light is stainless.  So stainless with a rose gold plating, and not aluminum with a copper sleeve.  Either works for me.  The point is that the weight is nice!

The Fenix bird logo doesn’t specifically do anything for me (I don’t have any special love for birds.  Or hate.  More of indifference.  I mean they’re delicious, so… ¯(ツ)/¯ ).  But this emblem is very nicely placed.  It’s raised, so there’s good texture from it.

Here you can see the tailcap, which has attachment points for the lanyard.  This tailcap reminds me of some bad haircut, but I can’t place it.  Let me know in the comments.

Whether the body is stainless or not, these threads (despite not being the cleanest – this is a 5-year-old light after all) are very smooth.


Inside there’s a spring in the tail end, and on the head is a simple mcpcb contact.  Not even a brass button or spring.  But hey, it works.  This isn’t a duty light.

Size and Comps

Flashlight Size:
Length: 2.6” (66.5mm)
Diameter: 0.6” (14.5mm)

Flashlight Weight: 1.1 oz. (31g) excluding battery

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

Included with the Fenix 15th Anniversary AAA is a necklace-type lanyard.


This lanyard attaches by first attaching the split ring to the flashlight.  There are a couple of holes in this unusual tailcap for lanyard attachment.

There is no pocket clip, magnet, pouch, or anything else included for carrying the Fenix 15th Anniversary AAA.

Power and Runtime

A single cell powers this flashlight.  The maximum voltage is 1.5V, so any AAA-sized cell will work.  Primary, rechargeable, both are fine.  Lithium-ion is not supported. aaa installed

The cell is installed in the usual way – positive terminal toward the head.  I didn’t use the primary cell that was included; I tested with a LADDA AAA (NiMH).

Below are a couple of runtimes.  The output claims are met for all modes.  There’s a big stepdown on High.  After that, the light maintains on the Medium output level for quite some time.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps (@1.5V)
High 85 1h 87 0.65
Med 25 4h15m 26 0.15
Low 8 14h30m 8 0.04

Pulse Width Modulation

No PWM on any mode!

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

The Fenix 15th Anniversary AAA is a twisty light.  Tighten the head for on.  Loosen for off.  It’s very simple.  And there are no hidden modes.


Here’s a UI table!

State Action Result
Off Tighten head Low, if the light has been off for >~5s
On Loosen head Off
On Quickly loosen then tighten head Mode advance (LMH)

LED and Beam

Fenix has used a Cree XP-E2 emitter in this flashlight.  This emitter is covered by a very short TIR, too.


I won’t say much about the emitter here, since (again) this is a 5 or so year old flashlight.  I will say, though, that with moderate pressure to unscrew the driver, I was unable.  So I can’t comment about emitter swaps.  Also, I have a sneaking suspicion that you’d have trouble fitting another emitter under this very short TIR.  But you’re the expert on that!

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!


What I like

  • Very nice looking
  • Great embossed “mythical phoenix” insignia
  • Good user interface (despite being twisty) – no hidden mess to muck it up
  • No PWM
  • Hits output claims

What I don’t like

  • Twisty
  • No pocket clip
  • Emitter green tint but again, a 5-year-old light… can’t fault it too much.
