Olight i3T Plus Ancient Bamboo Flashlight Review

Olight i3T Plus Ancient Bamboo Flashlight Review

Olight has released the i3T Plus flashlight in an Ancient Bamboo finish. The finish is antiqued, textured, and looks like bamboo! How great!


Official Specs and Features

Here’s a link to the Olight i3T Plus Ancient Bamboo flashlight product page.

Versions

There are three bodies of the i3T Plus. Two are aluminum: black and blue. And there’s this solid copper “Ancient Bamboo” finish.  I believe they all have the same emitter and are otherwise the same, too.

Short Review

I’m not normally just the biggest fan of this format of light – two AAA in series.  However, the finish and styling on this Olight i3T Plus Ancient Bamboo flashlight really sells it for me.  Add to that the fact that it’s not even very expensive, and certainly not expensive for a solid copper light.  The user interface is fine and the output is fine.  All in all I’d call it quite a deal for solid copper! Plus the finish is panda-approved!

Build Quality and Disassembly

Olight i3T Plus Ancient Bamboo flashlight

Well, check out that finish! Let’s forget everything else about this light and just talk about that finish. The design is called “Ancient Bamboo” and you’re going to love it! Or hate it, in which case there’s pretty much no reason to continue reading here. The flashlight as a flashlight, flashlights just fine! But the finish, well now that’s something interesting!

The light looks like bamboo!  Being long and slender, it even especially looks like bamboo. Maybe being so narrow, the nodes are too close together but your panda will. not. care.

Despite the very textured finish, Olight still sticks its branding on the end.

On the inside is all shiny and clean copper, though.  These threads are very smooth, and all in all the light is very weighty because of all that copper.

Down into that barrel is just a contact point – no spring.  But the tailcap has a nice beefy spring.

Size and Comps

Weight (g / oz) 95.9g / 3.38oz (Including Batteries)
Length (mm / in) 133mm / 5.24in
Body Diameter (mm / in) 15mm / 0.59in

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

The pocket clip, which is arrives installed, is a two-way clip.  There’s a lanyard hole in the shoulder, too.  At one point I didn’t like these clips, and while I still prefer the more traditional type, these have grown on me a little.  Whatever you think about the clip part, it is held snugly on the body.

The clip hug, seen below.

No lanyard is included, though the pocket clip does have a hole that would allow easy connection of a lanyard.

Speaking of the clip fitting snugly… I’d probably say just don’t take it off at all.  Under the clip the body still has texture, and it’s sort of a minor nightmare to reinstall the clip over this texture.

Power and Runtime

Power is provided by two AAA cells.   Olight does include two primary cells, but all my testing was done with Eneloop AAA NiMH or Amazon Basics AAA.

As with most flashlights, the positive end of the cell goes toward the emitter.

Here are runtimes for both modes.  Nothing really surprising here.  The emitter does blink at the end to notify the user that the battery voltage is low.  This seems to start when the cells are individually around 0.9V.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens
High 250/100 1/480m 249
Low 15 28h 11

Pulse Width Modulation

Not really any PWM to be seen here, which is good.

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 switch is a mechanical forward clicky.  It’s very clicky and clicks on the downstroke and upstroke.  The click is quite loud and extremely “positive.”

There’s a good bit of travel, too.

Here’s a UI table!

State Action Result
Off Click Low
Low Click High
Off Half-press Momentary (Low first, another half-press for high)

The light will revert to low as the next mode once off for 2 seconds.

LED and Beam

The emitter used in this AAA light is the Philips LUXEON TX – or at least that’s what the original was.  I don’t think this part has been updated, so that’s what I’m going with here too.  The emitter utilizes a TIR reflector, for a nice even beam.

I’m basing that on the emitter appearing exactly like the emitter in my Olight i3T Titanium.

The head does not have any relief, so no light escapes while headstanding.

LED Color Report (CRI and CCT)

This is a cool white emitter, but not that cool white.  As I’ve said a lot lately, Olight catches hate for “cool white” and many recent lights just don’t display that.  5600K is fairly reasonable!  The CRI is low, at around 71, and the dUV is positive, so the emitter can be seen as having some green tint.

Beamshots

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!

Conclusion

What I like

  • Uh, Ancient Bamboo, yes, please!  It’s very neat.
  • Solid copper body makes this light a great beefy weight
  • Simple UI
  • AAAx2 format (with alkaline/NiMH support)
  • TIR optic beam profile
  • No strobe!
  • Square-cut, high-quality threads

What I don’t like

  • No Nichia option
  • Low CRI
  • High doesn’t hold out long enough
