Convoy T2 14500/AA Flashlight Review

Convoy updated the T2 – the new version supports both AA and 14500 cells! My copy has a warm Samsung LH351d, too. Read on for thoughts and testing!


Official Specs and Features of the Convoy T2 14500/AA Flashlight

Here’s a link to the product page at mohrlumens.com.

Versions

Of course there’s the original version of this little light.  That version supports only AA cells.  Of this version (which surprisingly, frustratingly doesn’t seem to officially be called “v2”) there seems to be just one body but multiple emitters.  MohrLumens offers two of those – Nichia 219c 4000K, and Samsung LH351d 3500K (seen here).

Price

The Convoy T2 (14500/AA Version) Flashlight is selling for $13.95 right now.  I recommend MohrLumens.com, which is shipping from the US, and has stock right now!

Package and Manual

There is no manual.

Build Quality and Disassembly

convoy t2 updated 14500/AA flashlight feature photo

Standard Convoy fare here.  This is like a tiny S2+ in hand.

In fact as far as the build goes, I wouldn’t say there’s anything at all different from the original Convoy T2, which I reviewed here.  The build quality is the same, exactly.

I would actually venture a guess that only the driver and emitter has been updated, in fact.

convoy t2 updated 14500/AA flashlight lanyard

This lanyard ships installed.  So does that pocket clip.

Headstanding is a breeze!

The knurling here is perfect; no complaints.

Starting at the top and going down – you’ll notice some knurling on the head where you should grab if you’re a “head removing” kind of cell swapper.  I’m not.  Note that the bezel will unscrew too, so be sure you grab on the knurling (and not the bezel) when removing the head.

There’s limited printing on the body.  Just brand and model.

convoy t2 updated 14500/AA flashlight body

Again, the knurling is great.

And the tailcap has some knurling too, which aids in tailcap removal.  I opt to use the tailcap for cell swaps, because the threads on this end are anodized, and I prefer that level of smoothness.

convoy t2 updated 14500/AA flashlight tailcap

Here are those threads.  Anodized, not too long, and very smooth.

convoy t2 updated 14500/AA flashlight tailcap off

That tailcap has a nice beefy spring too.  Also note the brass retaining ring.  The reverse clicky switch is very accessible for maintenance.

convoy t2 updated 14500/AA flashlight tailcap spring

The head has only a brass button.  Also note the unanodized threads on the head end.

The cell tube is positively not reversible, and not just because one end has anodized threads and the other doesn’t.  The threads are not the same, and don’t mate!

There’s the emitter, with the bezel removed.

Size and Comps

Size: 21mm (diameter), 93.3mm (length)
Weight: 51g

If a light will headstand, I’ll show it here (usually the third photo).  If a light 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 format.

Here’s the new T2 with the original T2.  On my original (right, below) I didn’t actually have the parts snugged tight (I keep it mechanically locked out, despite it being a mechanical clicky).  Sorry about that – but they are the same!

The photo below is after I’d tightened the parts….

Retention and Carry

There are two means of carry for this T2.  They both ship already attached.  First is the pocket clip, which is a fairly standard friction fit non-deep carry clip.

The clip hug on this one is TIGHT!

convoy t2 updated 14500/AA flashlight pocket clip hug

So tight in fact that I couldn’t remove it to display that it can go on the head or tail end with ease.  There’s a groove on both ends of the cell tube.

convoy t2 updated 14500/AA flashlight pocket clip

Because of this, the T2 could reasonably be used as a hatlight.

There’s also a lanyard included.  It ships already attached, as follows:

I feel like that’s the “wrong” way, and I swap it over to the way seen below:

Importantly, this allows smooth tailstanding.

Power and Runtime

The coup of this new version is that it supports both lithium ion cells (aka 14500), and AA sized cells (primary, alkaline, NiMH, etc).

convoy t2 updated 14500/AA flashlight both cells

Two things about that.  The cell tube is surprisingly … tight… and wider diameter cells will not fit.  I had at least 14500 cell that was too wide, and wouldn’t even slide into the cell tube.  Secondly, button tops seem to be required.

The cell installs in the usual way – positive end toward the head.

Below are a couple of AA runtimes.  I used an NiMH cell for these tests.  Output is very stable with NiMH.

convoy t2 updated 14500/AA flashlight aa runtime graph high

I did not note low voltage protection with 1.5V cells, but the light does step down to “practically negligible” output when the cell voltage gets low.

And here are a couple of runtimes with a Vapcell 650mAh 14500.  Output is much higher with the lithium ion cell, and actually holds output for a reasonable amount of time before stepping down.  Then the output becomes unregulated, and eventually the light shuts off.

convoy t2 updated 14500/AA flashlight 14500 runtime graph high

Output on medium looks as above, after the stepdown.  Drifting downward with the cell voltage.  In this case the light didn’t shut off, but on bench power I did observe the light shutting off at 2.7V.  So I’m satisfied with the low voltage protection on this light.

Pulse Width Modulation

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  And here’s the worst PWM light I have ever owned.  Also one of the very first lights I ordered directly from China!

User Interface and Operation

The UI is simple.  It’s a tail switch – a reverse mechanical clicky.

Here’s a UI table!

State Action Result
Off Click On (Mode Memory)
Off Half Press No Action
On Half Press Mode advance (1%>10%>35%>100%)
On Click Off

Compared to the previous version, the user interface is greatly improved.  There’s an added mode (4 instead of just 3) and there are no strobe modes.

LED and Beam

The emitter in this new Convoy T2 edition is a Samsung LH351d, in 3500K temperature.  It’s quite nice, and certainly worth the $14 you’ll pay if you’re just interested in testing out this emitter.

convoy t2 updated 14500/AA flashlight emitter

The reflector is smooth with just the lightest bit of orange peel finish.

convoy t2 updated 14500/AA flashlight reflector

There’s a green o-ring in there too.  I don’t think that o-ring glows, though.

convoy t2 updated 14500/AA flashlight reflector

The bezel is flat, so no light escapes when headstanding with the light on.

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

AA:

As you can see, 14500 is noticeably brighter.

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

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

Conclusion

What I like

  • Supports “all” the (common) cells that can fit into the tube!  (14500/AA)
  • Great emitter
  • Good user interface (and certainly better than the old one!)
  • Build quality is good
  • Great price, at $14.

What I don’t like

  • No other colors than black!  Let’s see this one in as many flavors as the S2+.

  1. A bit curious how you find this one compared to the Skilhunt E2A, which also takes both AA and 14500 cells.

    1. Build quality of the Skilhunt is better (maybe even “much better”). Also I like the size better on the E2A… The extra mode on the Convoy is appreciated.

    2. I have both and I generally prefer the Convoy (mine has the Nichia 4k emitter) for a couple of reasons. The first is that the clip is reversible and the light can be used on the bill of a ball cap, which I actually have done many times. It’s a little heavy to be perfect, but sure does come in handy sometimes. Skilhunt missed an opportunity by not machining the gap near the head of the light a touch wider to accept the clip.
      The switch on the Skilhunt is super stiff and changes modes nearly every time the light is switched off. To be fair, the Convoy also does this, but not every single stinkin’ time. Also, low mode on the Skilhunt is not low enough.
      It is a well made light and noticeably smaller than the Convoy.

      The only con I have on the Convoy is that the tube is tight and I have had to unwrap some rebranded cells to get them to fit inside.
