Klarus Mi1C Titanium Flashlight Review

Preface

I knew when I reviewed the Klarus Mi1C aspheric that I wanted to review these ‘nicer metal’ versions with the reflector.  FastTech send this titanium version, and I’m pleased to put it through the paces!


Official Specs and Features

Versions

As I’ve mentioned above, there’s an aspheric version available in aluminum.  But the version I’m reviewing here is available in titanium, raw copper, and “dark copper.”  There are no emitter options

Price

At FastTech, the copper version is available for $45.  The titanium version is around $55.


Short Review

I enjoy this light.  I liked the aspheric, for as much the overall quality as the asphericness of it, and this one’s good in the same way.

Package and Manual

This is a nice package – a hard cardboard sleeve, and a ribbon attached to a box for pulling the box out.

The box is largely unadorned, but FastTech adds their inventory sticker to the front.

The manual is nice and complete.

Build Quality and Disassembly

This is a very nice little titanium light.  I love the pineapple style knurling, and the finish has a very nice shine.

33_zeroair_reviews_klarus_mi1c_ti.jpg

One thing notable about this light is how shallow the reflector is.  Probably a product of this same body being used for an aspheric and a reflector based light.  Either way, I like how visible the emitter is.  Nicely displayed, it is.

34_zeroair_reviews_klarus_mi1c_ti.jpg

Here’s a close up of the pineapple knurling.  There are also some fins around the head, for better heat dissipation.

19_zeroair_reviews_klarus_mi1c_ti.jpg

Here’s a simple disassembly of the light.

28_zeroair_reviews_klarus_mi1c_ti.jpg

The tailcap has a big spring, while the head has a smaller spring.  Neither of these springs are very stiff.

The cell tube has a silk screen to show the orientation for the cell.

29_zeroair_reviews_klarus_mi1c_ti.jpg

The threads are triangle cut, but do seem to have a little flat top.  However they’re made, they’re some of the smoothest titanium threads I’ve ever handled.

Size

Officially

•Dimension: (Head) 19.8mm x (Body) 20.5mm x (Length) 54.5mm.
•Net Weight: Titanium 33.2g (1.17oz) / Copper 56g (1.98oz)(w/o battery).

This is a small light!

Here’s the aspheric brother light:

And finally, one of the smallest 16340 lights out there, the Olight S Mini (Stainless Steel).

Retention

The pocket clip (which comes already attached) is the collar variety.  It has a very small mouth, but a big pocket shoulder.  It’s a good clip, but the mouth really needs to be bigger.

22_zeroair_reviews_klarus_mi1c_ti.jpg

The clip has a few TorchLAB BOSS-esque holes, into which could be connected a lanyard or cordage.  Normally I don’t like using clips this way, but this being a collar clip makes it a perfectly reasonable use.

21_zeroair_reviews_klarus_mi1c_ti.jpg

The clip is completely removable, and the light should maintain its waterproofness.

There’s also a magnet in the tailcap, which is plenty strong to hold the light in place.

Power

A single 16340 powers the Mi1C.  Klarus provides a “700mAh” 16340 with this little light.  While the light doesn’t have on-board charging, the cell has micro-USB charging.  Note that a micro-USB cable isn’t included.  That the fit of the included cell is very snug.  The manual states a working voltage up to 4.2V.

Here’s a runtime on Turbo.  Pretty heavy stepdown from Turbo, and then a fairly well regulated output for the rest of the runtime.  (I have this graph labeled “Turbo” – they call it “High”.)

36_zeroair_reviews_klarus_mi1c_ti.png

The runtime on High is absolutely flat.  (I have this graph labeled “High” – they call it “Medium”.)

37_zeroair_reviews_klarus_mi1c_ti.png

In neither runtime did the light really shut off (LVP), but it did switch to extremely low output.

The chargetime is very consistent, at around 0.33A.  For such a small cell, that’s fairly good charge current, at about 0.5C

38_zeroair_reviews_klarus_mi1c_ti.png

I charged this 16340 in a couple of random chargers around the house, and the charger shut off due to temperature protection.  That makes the second of these Klarus cells to get very hot during charging.  As a result of this, I’d generally recommend to either not use them, or charge them with their own port, and not in a charger.

User Interface and Operation

There’s a single switch on this light.  It’s a side e-switch.  It’s small but a normal size for a small light (and the same size and texture and clickiness as many Olight switches.)  The UI is fairly intuitive.

20_zeroair_reviews_klarus_mi1c_ti.jpg

Here’s a UI table!

State Action Result
 Off Click On (Memory)
 Off Hold Moonlight
 Off Double Click Strobe (fast, alternating)
 Strobe Double Click SOS
 Strobe Click Return to previous state (including off)
 On Click Mode cycle (L>H direction)
 On Hold (short) Off
 Any Hold (long) Lockout (confirmed by double flash)
 Lockout Any Lockout indicator (double flash)
 Lockout Triple click Unlock
 Off Triple click Battery indicator*

* Only with Li-ion 16340 cells.  Three flashes = 70-100%, two flashes = 30-70%, one flash = <30%.  When below 10%, the light will flash twice every three minutes.

That UI looks a little complicated (if you think long tables are necessarily complicated) but in general use it’s pretty simple, and unlikely that you’ll get an inappropriate mode accidentally.  I am pleased that the light offers a battery check option!!

Modes

 

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
High 600 1h12m 473* 2.42
Medium 45 5h37m 47 0.07
Low 10 32h 7
Moon Light 1 6d

* That’s not 473 ANSI lumens – the stepdown was quicker than 30 seconds.

LED and Beam

Klarus chose a Cree XP-L HI for this whole series.  Maybe that’s an odd choice for an aspheric – it’s an emitter normally chosen in throwers.  This light isn’t a thrower, but this emitter isn’t a bad choice for it.  The reflector has light orange peel, and overall the beam profile has a fairly tight spot, but there’s a reasonable amount of spill.

Random Comparisons and Competitive Options

Here’s a relevantly filtered page on parametrek.com. There aren’t all that many XP-L HI 16340 lights.  I like them….  I would love to have more!  This is maybe the only titanium option, aside from the ‘very’ special JETBeam Jet-II Pro, which is quite striking (that’s a strike bezel joke).  Among the other choices, only the Fenix E16 looks to compare to the Mi1c on size, and it’s only available in aluminum.

Conclusion

What I like

  • Availability in copper and titanium
  • Output is good on high
  • Stable output after stepdowns.
  • Great build quality
  • Package includes cell

What I don’t like

  • Ramp when switching to or from High
  • Switch is a little hard to get to (that’s really more of a measure of this light being so small!)
  • Pocket clip gets in the way when screwing the light together

Parting Shot

Unfortunately, no, the light doesn’t work with a button cell in this configuration.  However I think it could, if you wanted to slip a piece of foil in there and make the contacts hit just right.


Up Next

Not sure what (if anything?) I’ll be able to wrap by tomorrow, but Friday I hope to have another big light!
