Klarus XT1C Tactical Flashlight Review

Preface

Thanks to GearBest for another review light, this time a Klarus XT1C.

This one I did a group buy for (and that price is still in effect!), and when I set it up I asked Kathy to please send one along for review. She did, and here’s the review!

I do have a coupon and a great price, but unfortunately it’s not a public coupon. PM me or ask in the comments and I’ll send it to you. It’s quite a compelling coupon.

Short Review

I love this light for it’s “Outdoor” mode (the non-tactical group), because I love the momentary access to Low. It’s also a sturdy light, and the size is very good.

Long Review

What’s Included

  • Klarus XT1C
  • Klarus 16340 700mAh
  • Spare o-ring
  • Lanyard

Pictures

Here are the photos, and beamshots, and a runtime.

Package and Manual

This XT1C comes in a plastic package, much like what Olight uses so often.

02 - vEaJJxU.jpg

There’s a lot of text describing the light and it’s features etc, which GearBest covers with their sticker.

03 - MjkNeCL.jpg

The light is held in a plastic tray, and the accessories are in a tiny box at the bottom of the package. The manual is one long fold out affair.

“XT” by the way, stands for “eXtreme Tactical”. Yes, yes it does.

Build Quality, Disassembly, and Durability

I have been quite pleased with the build quality of this light, though I should have expected it. All my other Klarus lights have been great; this one is too. The knurling is of the “pineapple”

08 - swZ9nwM.jpg

variety (like the Mecarmy PT16, but less rounded). The switches are “protected” by some tailcap parts, which also allow for tailstanding. The threads are not anodized, but are big and square cut. I like anodized threads – I think they’re harder to damage by careless threading. But these are beefy enough that I never really felt like I was about to damage them. The clip is a spring clip, and is the ‘new standard’ – though in this case it’s decidedly not my favorite. The quality is fine, though. There are springs on both ends: the head has a gold (colored?) spring, and the tailcap has a thick double spring. For a tactical light, this seems like a must.

10 - 1bT2Bw7.jpg

Bad news as far as disassembly goes, however. I don’t see much access to either end of the light. The driver looks to be press fit. So if you aren’t in love with XP-L HI, then there might be better options out there. The tailcap does look to unscrew, but I was not able to unscrew it. It’s feasible that the head will also unscrew from the driver, but again, I wasn’t able to budge that.

This light held up to my normal every day set of abuses just fine. All the switches actuate very well, and nothing ‘gave’ even a little.

Size

As I measured:

Head: 23mm
Tail: 23.69mm
Length: 84.86mm

It’s not the smallest 16340 light available, but as a tactical light (ie, dual switch), it’s a good size. There’s definitely not enough room for an 18350. For holding in one’s hand the way you see people hold a light when also holding a gun, this length light is almost necessary. So it’s impossible to deduct any points whatsoever for the length.

Retention

The pocket clip comes installed, and is the ubiquitous spring clip.

07 - OSvyBn3.jpg

Nothing special, and nothing bad about the clip itself. I do not care for it’s location on the body, unfortunately. It is too central, not allowing for good deep carry. It’s generally bezel up, too, though it can be reversed (and then is even higher in the pocket!). I haven’t had it tip out and get lost.

There’s a simple lanyard. The kind that doesn’t have a bunch of extra bits, and isn’t easily broken. The lanyard connects on the tailcap, though it could also connect through a hole in the pocket clip if you wished.

Power

Power is through a single 16340 cell, and a 700mAh 16340 is generously provided! CR123A’s will work of course. 18350’s will not fit, as the tube is just big enough for 16340 cells. There is no on-board charging. I believe this is a protected cell, but I don’t see that verbiage on the cell or documentation.

I have to say, the inclusion of a 16340 is a very nice touch, especially on a light that doesn’t have on-board charging.

Runtime cutoffs: 2.54V for High, and 2.85V for Medium.

User Interface and Operation

There are two tailswitches – one with a rubber boot, and one with a rubber boot and a paddle switch. The non-paddle is the “power” switch, and the paddle switch is the “mode” switch.

04 - tK9yBPN.jpg

There are also two mode groups on this light. The first (and default) is the “Tactical” setting. The other is an “Outdoor” setting.

Tactical Group:

State Action Result
Off Primary Click High
Off Mode Momentary Strobe
Off Mode Hold Strobe (constant)
On Primary Click Off
On Mode Click Mode cycle (H>M>L)
On Mode Hold Strobe (constant)

Outdoor Group:

State Action Result
Off Primary Click High
Off Mode Momentary Low
Off Mode Hold Low (constant)
On Primary Click Off
On Mode Click Mode cycle (L>M>H)
On Mode Hold SOS (constant)

To switch between the mode groups:

  1. Have the light on.
  2. Hold the primary button (light will go off- keep holding), for 5 seconds.
  3. Light will flicker very fast: Click Mode and light will flash 1 (for Tactical) or 2 (for Outdoor).
  4. Release after desired mode flash.

Notes: SOS only accessible in Outdoor mode.

LED and Beam

The LED is a single Cree XP-L HI V3.

09 - 4XQEipn.jpg

I find it to be a cool XP-L HI, and I’m normally a huge fan of this emitter…. In a tactical light, I don’t think CW is any huge surprise, but I’d still like it to lean toward neutral, since it has the outdoor modes.

The reflector is not too big or deep, but given the size of the light (marginally big for a 16340), there’s plenty of reflector. It’s also a smooth reflector, so the beam is tightly concentrated – there’s a distinct hotspot. The beam is also very smooth – no artifacts to speak of.

I didn’t throw this on my Oscope, but I’m fairly sure I can detect some PWM on the low mode. I’m extremely sensitive to PWM, so I really doubt most people would ever notice it.

Random Comparisons and Competitive Options….

As far as my searches go, this is the only tail switch XP-L HI 16340 light. It’s also unique in that it’s the only 16340 light with a paddle switch (that I could find, at least). There are some other “tactical” 16340 lights, however, like the Thrunite Archer 1c V2. That just has a tail clicky (no paddle).

Conclusion

I typically have no huge need for a tactical light, but I like this one for the dual tail switch. I’d like it even more if it wasn’t CW, particularly for outdoor applications, but it’s still a fine little light. For tactical purposes, it’s a great size – fitting neatly in hand and allowing ease-of-access to the switches.

What I like

  • Dual Switch
  • Momentary paddle switch (particularly Low)
  • Versatile UI, including two mode groups

What I don’t like

  • Pocket clip
  • Cool White tint

Final Thoughts

This is a fun little light. I don’t even need tactical lights, but I happen to really like dual tail switches. That’s new, really – I didn’t used to care for them. But I like the versatility, and I find the modes to be quite easy to more or less just guess without having to commit the UI to memory. That’s a great feature.

Coupon

I have a great coupon for this light, but it’s only available through PM. So, PM me for the coupon and price if you’re interested!
