Nitecore MT06MD Flashlight Review

Nitecore MT06MD Flashlight Review

The Nitecore MT06MD is a flashlight using a Nichia 219b emitter. It runs on two AAA cells and has a nice positive clicky. Read on!

Official Specs and Features

Here’s a link to the Nitecore MT06MD flashlight product page.


There is only one version.


This light costs $31.95.

Short Review

This light is specifically designed for medical responders and the like.  It’s very nice that the Nichia high CRI 219B emitter is standard, and the size and shape are great for that application.  As a general penlight I think this is a win, too.

Long Review

What’s Included


  • Nitecore MT06MD
  • Spare o-ring (2)
  • Manual

Package and Manual

This light comes in a long and thin – but typical – Nitecore package.  There’s a window allowing the light to be seen, and a hangtag for easy store display.  And of course, the box is black and yellow.

Here’s the actual [English part of the] manual.


Build Quality and Disassembly

The MT06MD has a very nice build.  A build that’s clearly been well considered.  The aluminum body has machine marks… but they’re intentional machine marks.  I won’t say they’re intended for grip (they probably are), but they’re very fine lines.  They go around the light and don’t have any cross-hatching, and the light has no knurling.  It’s an interesting grip mechanism, and I’d be interested to know why they chose it.  I really like it though.  It’s fine enough that it’s not really visible, and only really noticeable when rubbed with a fingernail or something.  I’m sure there’s a great name for this type, but I don’t know it.

Another nice aspect is that this light has a metal button.  A flat metal button.  That means more for actuation than it does for tailstanding (the light’s balance means it won’t tailstand, even with the flat button!).


The head unscrews easily (to wit this is how cells are swapped), but the driver looks to be press-fit in.  So I’m not sure and doubt it’d be easy to emitter swap the light.

The tailcap cover also unscrews, revealing a rubber boot over the plastic switch.  This is why the light won’t tailstand, in fact.  I could not get the pocket clip retaining tail cap off to discover if the clip is removable.  It almost has to be, however.  As a matter of fact, this is exactly where the grip rings mentioned above get in the way – they hinder grip in the “unscrewing” direction!


Having said that about disassembly… why bother?  High CRI 219B anyway?  Is probably what you’d want to be adding anyway.


Bog standard 2x AAA light size.  Nothing extraordinary or exceptional.  The shape is a bit less curvy than the Thrunite Ti4, but that’s neither a complaint nor a criticism.  It’s a fine size and fits in pockets and the like just fine.

I measure it as 129.22mm, and about 14mm at the head end.


The only included way to carry this light is with the pocket clip.  It’s also a great way – it tends to disappear in a pocket the way I carry it.  It’s also really slim enough to be carried in the front pocket and would feel right at home in a lab coat with other tools.



The MT06MD is powered by two AAA cells.  I chose to use Eneloops, and they’ve worked great.  Primary cells work too of course.

Here’s a runtime graph on the highest setting (of 3).  Compare that to the claim of 45 minutes on high.

Cells (Eneloop AAAx2) were at both 1.49V at the start of the runtime test.  At the end, 0.86V and the second cell was initially [zero?] but bounced back to around 0.87V.  Ergo, I don’t trust that this light has any LVP at all, which is disappointing.  I can overlook that since NiMH is pretty safe anyway.

H: 3850 lux

10440 cells are not allowed in this light!

User Interface and Operation

There’s but one button on the MT06MD, and it’s the aforementioned metal tail reverse clicky.  The metal cap is actually over a rubber boot, and the action of the button reflects this.  I tried the switch without the rubber boot, and it doesn’t fly.

There are only three modes.  Accessing the modes works in the normal reverse clicky way.  There is no mode memory – the light always comes on in low.  This is purposeful since this light is designed for medical uses.  So, no mode memory always starts on low, reverse clicky…. this is shaping up to be a UI I love!  To change modes from low, just half-press the clicky to any of the three modes desired, in the order L>M>H.

The manual states that this light will step down after 5 minutes, to save battery.  I did not experience this during the runtime test.  I’m glad too; that would be a terrible feature.

LED and Beam

As discussed amply above, this emitter is the venerable Nichia 219B.  That means that out of the box this light has a great color/temperature and also has high CRI.  Nitecore quotes “≥90 CRI”.  This is an excellent development, and I hope it sells well so Nitecore will drop this emitter into some other lights!  (Nichia MH20 please!)

A “PDOT” (Precision Digital Optics Technology) reflector is used in this light.  That’s Nitecore’s special term for a reflector.  In this case, it’s smooth and also fairly deep.  The lens has an AR coating, too.  The deep smooth reflector gives a nice beam with a surprising amount of very “spot”, and a minimal-to-fair bit of spill.  On low for example, even at 6-10″, the spill isn’t even very noticeable.

The MT06MD does not use PWM for the low modes.


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


Random Comparisons and Competitive Options….

Clearly the first thing I’ll think of is the Thrunite Ti4, which I just reviewed.  Between those two, I’m going to almost always prefer the Nichia 219B light, and in this case that’s the Nitecore.  Build quality isn’t appreciably different.  I like the Nitecore UI except the 5 minute stepdown.

Aside from that, the 219B Nichia really separates this light from anything else in the 2xAAA category.


What I like

  • Nichia 219B emitter standard
  • High CRI standard!
  • I like the size and shape and color of the metal clicky
  • Able to be sterilized by dipping in alcohol!

What I don’t like

  • No low voltage protection
  • Mode spacing? Not really a concern to me but First Responders etc might like a lower low.
  • That Nitecore doesn’t have a single cell version of this light out yet
