XTAR D06 1600 Dive Light Review

Preface

My list of XTAR items reviewed includes many chargers, but only one light.  But they have out a new light.  It’s a dive light, with an interesting switch.  I’m no diver, but I did put the light through the normal paces.  Here’s that review!

XTAR isn’t new to dive lights.  They have a whole bunch!  So they have experience in the category.


Official Specs and Features

Versions

There’s only one version of this light.  This is an updated version, though, of the D06.  The emitter has changed, the output should be higher, and there are a few on-body changes as well.

Price

I’m not seeing this one for sale anywhere yet, so I am not sure what the MSRP will be.  Based on what I see on non-American sites, I think it’ll come in somewhere north of $115.


Short Review

Aside from the dive capabilities of this light, it’s a cool little light.  The magnetic switch works well (if a little laggy), and could be perfect for a user for whom a clicky isn’t acceptable.  The output is good and the regulation on even the highest mode is great.

Package and Manual

The D06 1600 ships in a very nice white flip-top box.  The box is printed with a nice photo of the product and on the back, specs and runtimes.

The light is held in place by a custom cut foam piece, and all the accessories are in a box beside.  It’s a very nice presentation.  And of course, it’s all very “XTAR blue” throughout.

zeroair_xtar_d06_1600-09.jpg

The manual is two sided.  Only one side is English.  It’s not terribly detailed, but it does cover the basic usage of the light.

Build Quality and Disassembly

Being a dive light, it’s reasonable to have a higher standard for the D06 1600.  It’s also reasonable to expect a more robust package; this light has it.

zeroair_xtar_d06_1600-41.jpg

The body is much thicker than usual on a similar 18650 type light.  There’s a rubber ring around the head to facilitate grip.

One thing you’ll note about this light is the big lanyard hole centered on the tailcap.  The previous iteration of this light had a more usual layout for the lanyard hole (ie, flat tailcap and hole on the side of tailcap).  I expect this setup is more ideal for actual diving, since when would you nee to tailstand the light while diving?

zeroair_xtar_d06_1600-23.jpg

The body has some reeding, too but overall it’s not all that grippy.

Both the head and tailcap have a “gold coated” spring.  It’s not really possible to see it in this photo, but the body of the light is really a double wall type setup.  I’m not sure if this is because the light will be underwater often and so it’s some kind of pressure maintenance setup, or just done for overall robustness.

zeroair_xtar_d06_1600-24.jpg

Here’s a close up of the rubber band.  It has the same feel as one of those yellow Livestrong bracelets we probably all know.  Grippy silicone.

zeroair_xtar_d06_1600-27.jpg

The threads on the head are anodized and square cut.  Thus it’s possible to lock the light out with a short twist.

zeroair_xtar_d06_1600-28.jpg

Size

The official dimensions are: 45mm (head) x 29mm (body) x 152mm (length)

As you can see, it’s a fair bit thicker than the Convoy S2+.  Of course it’s longer too, but it’s much more of a thrower.

zeroair_xtar_d06_1600-30.jpg

Retention

The only included means for carrying the D06 1600 is the lanyard.  This is a dive-specific lanyard, which has a longer loop and also adds a rubber coating for better grip.  The lanyard attaches through the dedicated hole in the tailcap.

zeroair_xtar_d06_1600-19.jpg

Also, not really for carry of the light, but something that does facilitate carry of the light is this aforementioned silicone grip on the head.

zeroair_xtar_d06_1600-29.jpg

Power

The D06 1600 is powered by a single 18650.  XTAR has included one in the package – a “3500mAh” protected 10A button top.  The light does not have low voltage protection as you’d expect.  When the voltage gets really low there’s noticeable inductor whine, and at around 2.0V the light shuts off completely (not LVP though, more likely the Vf of the emitter isn’t being met.)  Since the emitter has a Vf of over 11V, what it really means is that the boost circuit can no longer boost the voltage enough for the emitter.

The 10A cell is plenty for the D06 1600.  On the highest mode, the light is drawing around 3.5A

zeroair_xtar_d06_1600-38.jpg

I performed a runtime on the highest mode (here labeled Turbo, not sure if that’s the XTAR name for it or not).  Since this is a boost driver, we’d hope the output would be maintained appropriately for a reasonable amount of time.  It actually is, quite well.  For the first 10-15 minutes, the output stays near-start-level.  Not perfect, of course.  I didn’t do a water runtime test, but I suspect that with water cooling (ie in a dive), output would remain flat.  I read the 30 second out put as around 1300 lumens.

zeroair_xtar_d06_1600-44.png

I selected another somewhat random mode for a runtime test.  Not turbo, but above half way on the slider.  Output is absolutely flat after bouncing down in the first few minutes.  Then after around 3 hours, drops again.  The final drop is an extremely low output, and this mode will run until the battery can no longer supply enough voltage and amps to be boosted.

zeroair_xtar_d06_1600-42.png

The D06 1600 doesn’t have built in charging, but the package does include a single-bay li-ion charger.  This is not a random charger; it’s the XTAR Ant.  I have a bunch of similar chargers, but this is my first Ant MC1 Plus.

zeroair_xtar_d06_1600-31.jpg

It’s a simple charger, with micro-USB input for power.  There are no settings – just install the cell and charging will begin.  It charges at only 1A.  There’s a power meter indicating the charged state of a cell, in four bars.

The Ant MC1 Plus (the Plus is important; there’s also a non-“Plus” version) comes with its own manual.

zeroair_xtar_d06_1600-61.png

Charging looks pretty solid, at just under 1A.  It’s noteworthy that the cell tests well under the rated 3500mAh.  The charger put around 2900mAh into the cell.  I didn’t test the cell on my cell testing rig (look for more on that tomorrow!), so the cell wasn’t taken down to 2.8V or 2.6V for an actual capacity.  But based on what I normally see when testing cells, this measurement is just a little low for the rating of the cell.

zeroair_xtar_d06_1600-43.png

The charger is good, though.  Not a bad value at $7 on amazon, either.

User Interface and Operation

The user interface couldn’t be simpler.  There’s one switch on the light, and it’s a magnetic ramping switch.  When the light is off, the switch is most-tailward.  Pushing the switch toward the head ramps the light on.  There are no detents, and the ramp is smooth.  There’s a fair bit of resistance, but not enough to be any issue whatsoever (in fact, the resistance is confirmation that the switch won’t move on it’s own, and likely won’t move too much if bumped, too).

zeroair_xtar_d06_1600-20.jpg

And that’s it.  There are no special modes, no tactical modes, no other mode groups or anything like that.  It’s just a simple slide-for-on-to-desired-output.

Below, the light is off.

Below, the light is fully on.

Now this is a dive light and I don’t dive.  Truth be told I don’t really even love swimming!  But I found some water, and threw the light in there.  Here are some shots of that.  (I also don’t have an underwater camera, so….  these are maybe not all that useful shots?)  Except they’re useful to say that the light works great underwater, and while wet.  The switch is very functional underwater.  Yes, my water is very dirty.

zeroair_xtar_d06_1600-48.jpg

To be perfectly honest, the switch felt way smoother underwater.

LED and Beam

The emitter XTAR opted for in the D06 1600 is a Cree XHP35 HI.  The reflector is smooth and moderately deep.  It’s probably smaller in diameter than it looks like it’d be, again because the head is quite thick (like the body).

zeroair_xtar_d06_1600-18.jpg

Here are some random modes.  First is “as low as I could get it” which should be around 10 lumens, and then a few intermediate modes, and finally Turbo.

Random Comparisons and Competitive Options….

Here’s a relevantly filtered page on parametrek.com. There are quite a few single 18650 Cree XHP35 HI lights available with an IXP8 rating.  The thing that sets the D06 1600 apart is that it has a dive-friendly UI, and some accessories that make it suited for such.

Would this be a good non-dive light?  I think it’s a fine light if the magnetic switch is something that suits your needs.  I feel like it’s easier to manipulate, so if you need to manage some dexterity issues, then it’s a good choice.

Conclusion

What I like

  • Robust build quality
  • Magnetic UI slider
  • Throws better than claimed
  • It’s a full package light

What I don’t like

  • Doesn’t quite hit the lumen output

Up Next

I hope to have a full week of reviews!  Lights, chargers, cells, oh my!  Stay tuned!
