Greg McGee decided to call my bluff and donate one of his self-touted top of the line lights for my review. Several of you might recall my expressing doubts about this light in another thread, calling Greg out to a showdown with his pricey XML light. His confidence in his product was at stake against his reputation in a budget forum and yet he still sent me the light free of charge in exchange for an honest review. So is this light worth the extra bacon, and how does it perform considering its cost and similarities to other lights in this category?


Pros & Commentary:

MTE is back with a new version of the M3-2I. This time, it arrived equipped with a smooth reflector and a well driven Cree XM-L. My research indicates that earlier offerings were MC-E powered and equipped with TIR optics. I have several less expensive XM-L T6 lights I've purchased at Chinese web sites to compare it with. Greg mentioned that he asks the manufacturer for better “bins” to be installed in his lights. There does actually seem to be a positive difference, although this might be attributable to a driver that runs the emitter at close to 3A on high and paired with a great matching reflector to make use of the extra light. My example has a nearly perfect finish. I say “nearly” because even my expensive lights have some minor flaws... call me a perfectionist, but this is nearly perfect. The threads, engagement and torque required to screw the assemblies together is smooth and a nice tight fit over the o-rings. The body has double o-rings on both ends and an o-ring on the lens. No binding or cheap inconsistent threading here. I certainly wasn’t expecting it to be this good. I have the Aurora M3-2I which I will rate as a close equal in finish and quality. Up to this point, the Aurora was the nicest host of any budget light I had come across, both in fit and finish. The MTE has slightly better and tighter tollerences. The two lights also share the same threads, which allows me to interchange parts from one to the other and play “Lego lights”. This was of particular interest to me because the Aurora was quite a disappointment in terms of output and beam tint. It came equipped with an MC-E and larger TIR optics that didn’t play very well together. After going over the light to assure correct operation, I assumed the Aurora suffered from a poor bin MC-E until I temporarily held a smooth reflector against the LED and turned it on. It improved some using the reflector from the MTE... but only about 2/3rds as bright and still had an ugly beam pattern and tint compared to the XM-L. As Don had noted earlier, some LED’s don’t appear to work very well with some TIR optics. Surprisingly, the MTE XM-L played well with the Aurora TIR optic, which surprised me. It provided a WIDE linear hotspot, lots of flood and not much throw. Now I know that I can slap a XM-L in the Aurora and I’ll have a fantastic close range mega-flood light. As an aside for mods, the MTE has a brass pill that screws directly into the host and not the reflector. This allows you to unscrew the reflector/bezel assembly and use the body in candle mode. For those who are wondering how a XM-L might play in a different potential host mod, one only needs to remove the bezel from the MTE and hold the proposed reflector in place by hand to test the beam results. Can you guess what I've been doing with many of my reflectors and the new MTE? Stay tuned for a serious 3A, 3 mode, 2 x 18650 XM-L thrower mod in the near future.

This light arrived as clean and properly lubricated as any expensive light and required no fiddling to make it acceptable and working properly. Greg inspects each of them before shipping and replied quickly to my emails (probably to make sure he knew what he was getting into... lol) Shipping is within the U.S. and the light came in a padded envelope inside a firm cardboard box wearing a MTE label. Presentation is gift worthy, unlike the miserable boxes most of our cheapo lights come in. Time in route: 3 working days. Tailcap lockout is possible and consistently repeatable by unscrewing the tail cap 95-100 degrees (a slight bit more than 1/4 turn).

Water resistence appears to be as good as any non-diving light and should do a good job if submerged in shallow water. Tail clicky action is precise and requires medium pressure to activate and can be done single handed without feeling to mushy or firm. Mode switching is as it should be and seems very consistent (it doesn’t miss or skip modes, nor does it change in consistency as it heats up). The Aurora is horrible at mode switching and takes some getting used to. The tail cap allows a “Cigar” type hand hold and has a hole drilled for a lanyard - although one was not provided. The inside of the tailcap has a spring loaded brass plunger and the driver end has a spring soldered to it. This puts spring pressure on both ends of the battery and eliminates any potential contact issues or inadvertent mode switching when shaken. Speaking of which, shaking both the Aurora and MTE vigorously showed that the MTE held the battery with absolutely no perceptible rattling while I could feel the battery moving around inside the Aurora. The pill is brass and I could not remove it by hand. A strap wrench would probably remove it if necessary and I assume it isnt glued because everything else in this light comes apart quite easily by hand. Those that have the larger 18650 Aurora’s will be familiar with the respectable quality of the brand, but this one has a better finish and more precise tollerences between the parts that generally aren't noted until examining much more costly lights. Also, many pricey lights are glued so there is no potential way to easily upgrade them. Thankfully, this isnt the cast with the MTE. From the soldering to the close machined fit, this was obviously produced by skilled labor. IMO (in my opinion), it only lacks in possessing an original style of its own. But then, I purchased the Aurora based on the style and quality of the host, and that some day I might mod it if I didn’t like it. Well guess what? The 20mm XM-L star is already on its way from KD!

Probably the most outstanding (and surprising) feature is the way the emitter works with a comparatively small reflector. Most power lights get killed by reflectors of this size and depth but the XM-L does wonders with it. In comparing it to my larger KD C8 XM-L with smooth reflector, the MTE has a tighter (smaller) and brighter beam with greater throw.

It puts my Manafont 3-mode with smooth reflector to shame (although this is probably the brightest off-the-shelf P60 tested to date). I think the white tint of nearly 3 amps also contributes to the overall performance as seen by the human eye. Another pleasant surprise is how well it handles heat. It takes quite a bit longer to heat up than the heavily foil wrapped drop-in P60 XM-L that I have stuffed into a slightly lighter (less mass) 504B I used here for comparisons. I had expected it to get quite hot in a hurry but it didn’t. In general, I've noticed that the low vF of the XM-L seems to be rather cool running when carefully heat sinked as compared to the higher vF MC-E or P7 emitters when driven at the same current levels. While this host wont cool quite as well as the larger and heavier C8, it will surprisingly do about 75% as well. I thought for sure that this would be a total hand roaster and I am amazed to find it to be quite the opposite. In fact, the less bright and much heavier (due to its larger bezel) Aurora MC-E actually heated up far more quickly and ran hotter. Pic shows protected 18650, Utrafire 504B, MTE M3-2I.


Cons & Commentary:
The modes might be annoying to some. There is no mode memory and it starts out in high mode. For the many of you that have the KD C8, the MTE’s overall beam is brighter because it is much more concentrated and appears whiter. If you don’t mind having a blazing searchlight type mode as the default then this light is for you. Also, the mode sequence is unconventional: High, Fast Strobe, Medium, Low, Slow Strobe, SOS. The lumens spacing between high and medium is noticeable but still to high to be considered a medium mode. Low mode is entirely acceptable and much appreciated. The fast strobe is really quite fast and might be disorienting to some (as I suppose it is intended). If I had my wishes for modes, I would opt for High, Medium high, Medium low, Low; with memory. The driver and switch offer solid reliable easy mode changing so even a 6 mode brightness capability without the blinking modes would work well in this host combination. The “cigar carry” fixture is molded into the tail cap. Most lights in this price range have a separate Cigar carry/lanyard ring that can thread on and off between the tailcap and host to remove this option and streamline the body if preferred.
There is a slight dark spot in the middle of the beam that shows up during whitewall hunting. I find this to be true of nearly all my high powered lights and my eyes are very sensitive to it, but this disappears outdoors (where lights like this are meant to be used). To quantify: the donut hole isnt nearly as intrusive as the Jetbeam M1X. I haven't tried tweaking it by tightening or loosening the bezel. The emitter is slightly off center in the reflector but has absolutely no impact on the beam quality, concentricity or output performance that I could detect.
I would like to see an AR (anti-reflective) lens included and perhaps an extra GITD (glow in the dark) tail cap, extra O-rings and lanyard; as is customary on most other lights of this price range.


Features / Value: ★★★★

When I consider this single 18650 light, I look towards reliability and durability. This light is tough and well built, carefully fitted and assembled, light weight and compact with a thick walled casting. Compared to my Olight M20 (which is designed for a weapons mount to handle the punishment of firing recoil), Id feel more confident that the MTE would surviving more brutal punishment and continue working. The emitter star sits recessed below a cuff machined into a brass pill. This prevents the body from jamming the star into the bezel when screwed together, thus eliminating any chances of a dead short occurring from the host tube scraping through a paper doughnut ring and up against the star soldering pads. It also allows the emitter to sit inside the reflector rather than be submerged 1-2mm below it. Although it comes equipped with a threaded removable strike bezel ring, it retains the lens and cant be used without it. The crenulations from the bezel are not visible in the beam pattern, thanks to a relief angle machined towards the inside of each crenulation to prevent the ring from absorbing light. You might be amazed how many lights are severely impacted by their ring bezels subtracting hundreds of lumens. My expensive Olight M20 is no exception, and I wont use it with the bezel ring attached. The host is handsome and based on a proven design, then further refined in the quality of manufacture, fit and finish. It is easily opened up for modifications and can share parts with some other lights. The site offers an optional holster and a different lens as well as Tenergy brand batteries and charger.

Battery Life:

High ★★★☆☆

Medium ★★★★★
Low ★★★★★ + ★★★★★ + ★★★★★ – its about time we see this in 18650 high powered lights.

While I didn’t do a run time tests, this will be average for similarly driven XM-L single 18650 battery combinations. This light is geared to provide enormous amounts of light on high and still be DAM bright on medium mode. If you want more battery life, don’t run this light or others similar to it in high mode all the time. At 1.5A the XM-L T6 is said to be 20% brighter than the XP-G R5. It actually seems brighter at lower drive levels because of the comparatively enormous hot spot. Believe me, medium mode still puts out an enormous amount of light (about similar to the Aurora MC-E on high mode that it replaces).

Tail measurements with a calibrated DMM on a freshly charged flame Trustfire @ 4.20V netted the following results:
High: 3.15A settling to about 2.85A after 30 seconds
Medium: .73A -You would think its burning at least twice that amount considering the apparent brightness.
Low .01A - No kidding and Hallelujah!! Is there anyone out there that is not sick to death of low modes being so darn bright that it completely decimates your night vision at initial turn-on?? Say “good-bye” to that ever happening with this light (if you can get it into low mode before being blinded). You can simply block the lens and count the half-clicks to get into low mode but its not convenient. Low is slightly brighter than an ITP A3 in medium mode (a small efficient AAA chain light many of us adore)
Yes, I double checked all the readings several times. While the medium mode is still darn bright (thanks to a great reflector and the efficiency of the XM-L) it could still be toned down a bit more. I suspect it would not seem as bright if the reflector were larger because the MTE culminates an unexpectedly tight beam without perceptibly losing lumens with the smaller reflector. Beam angle is about 30% tighter than my KD C8 example with SMO reflector.
Range to target: 30 feet

Light Output: ★★★★★

Its an XM-L driven at fairly high amperage, focused through a well matched flawless reflector that provides a fairly tight beam pattern. The tint of the emitter is slightly preferable to me over the other XM-L offerings I've seen thus far and it gives more contrast at longer distances. Its only slightly larger and nearly the same weight of P60 based lights yet provides a sizable amount more lumens while providing superior heat management. So what makes it work so well? I'm not sure if it’s the better emitter, the way the XM-L works with the reflector, the quality of the reflector and its finish or the likely combination of all 3 working in concert. To date, I would have to say this light is probably the brightest light I own when considering size to lumen ratio. Its easily my brightest single 18650 light yet.


Summary:

I deliberately did not provide an overall rating for this light for a few reasons. First, it is not intended as a budget light. While it shares many similarities to the Aurora, it is clearly manufactured and fitted to a higher standard. This obviously takes more skill, time and money to produce. The modes and sequence in which it is offered might be a deal breaker for some yet an advantage to others. It would be nice to see a choice of driver mode options at this price point. Since I already have so many lights, I simply select one or two for the proper intended situation before night fall. As far as I know, there doesn't yet exist a light that does everything well, hence the reason why some of us have several of them. This is one of few lights at any price that worked straight out of the box, and without any adjustment or modifications to make it work properly to my satisfaction. Beyond the mode preferences, I would recommend this for professional duty carry and put it up against any light costing 50-100% more. Greg seems to offer good personal support to his customers. Although we got off on the wrong foot because I had serious doubts about his initial claims (when he boasted in an unrelated thread), I will agree that this light has lived up to his claims.... something I DID NOT EXPECT.

As mentioned before, IMO, if this light was better than my larger and heavier Aurora, it was to be gifted to someone very special... an Alaskan Bush Pilot Guide and very dear friend that camps in the extremes of the wild unforgiving mountainous outback. He is quite often responsible for many lives that hire him for his piloting and guide services. I need to know that when he pushes the clicky, its going to turn on every time, especially after he drops it (which he will certainly do many times). So far, this appears to fit the bill better than any other light in my single 18650 high powered light collection. Everything else is secondary for the non-flashaholic that will be using this to depend on, but its nice to know its all there. I’ll let him compare this to my Aurora and other XM-L lights so he knows what a great light he is getting. Is it worth the extra cost to you? That will be for you to decide based upon your own personal needs and budget. It is however, the only one I will give to someone I know that will likely appreciate it the most - and ultimately at the worst possible time.

It is important to mention that no one should rely one one single light and battery where life and safety might be at stake. Under these anticipated conditions, ALWAYS, ALWAYS CARRY A SECOND AND THIRD LIGHT AND SUFFICIENT BATTERIES FOR EACH. As a SCUBA wreck exploration certified diver and Search & Rescue pilot, I've been drilled with that information and pack this way every time I travel far away from man-made light sources or civilization.

I would also like to apologize to Greg. You put your reputation on the line and risked additional harsh criticism in front of hundreds of others, which I was quite ready to dish out and even anticipated. I am duly impressed with your product and am pleased that it performed as you had described.... straight out of the box. As mentioned, I believe the driver changes I had mentioned along with a descent lanyard, A/R lens, user changeable GITD tail cap and extra O-rings would round out this package nicely. Other than that, I wouldn't change a thing.

Very nice review - well done ...

Very nice review and a very good looking light, but it costs almost 100$ with the XM-L option (65$ with MC-E)...

Yes, my colleague has this light and I found one big con and that is the on/off protruding light switch design can sometimes accidentally turn the light on if you're keeping it in your coverall. The comparison with the KD C8 CREE XML T6 1000 lumens light is also correct for I own the T6.

FlashPilot, thanks for doing such an extensive and thoroughly documented review. It's reviews by people here on the forum that make me decide whether or not I want to purchase a light. I don't pay much attention to the reviews on the websites. Great job as usual!

Great review with video FlashPilot!

I also love your choice of music. They're one of my favorite bands.

Flash - It is reviews like this that encourage me to improve and do a better job. Very well done, indeed.

Thanks very much FlashPilot! Extremely thorough review, and excellent attention to details. Above all, I'm extremely impressed that you managed to keep this review objective and positive despite a prior disposition to this product.

I can't yet learn to like the styling of this light or other similar ones. But I do really like the sound of that low mode!

Frontapage'd and Sticky'd. Thanks!

Im glad you all enjoyed the review. This driver is making me rethink the prospect (and major hassle) of programming my own driver modes with a PC interface (save all the blinking modes and odd sequence). Every high powered light should have a minimal output option along with the ability to drive the emitter at max. Im still amazed at how well the XML performs with minimal current.

Nice review flashpilot. Looks like a good light but expensive.

It would be a tempting light if the modes where not so horrible. High-med-low is all i'd want, or even have a strobe at the end. But that 6 mode in that order is just brutal. I do like the styling, and with your review I think it'd be a nice light otherwise! Well done review!

Very detailed review and nice light. Its amazing how much light its putting out at .73 amps. High is brighter but wow thats over 4 times the current flowing! Makes me want to get an XML bad.

If anyone wants a non-portruding switch I usually just throw in an extra P7-D type switch assembly for free. If anyone wants a non-protruding switch, I usually just throw in an extra P7-D type switch assembly for free, but I can only do this at the time you order your new light. (I have to pay someone to ship the products and its very costly). Just add the note that you came from budgetlifhtforum and want a "non-portruding" switch in addition. I always order extra for law enforcement as the anti-roll doesn't fit in the standard police holster. The police have been going crazy for these.

I like the portruding switch with the anti-roll. Rolling on the rocks is good for beer, not good for flashlights...

Great job Flashpilot!

Thanks,

Greg McGee

"the mode sequence is unconventional: High, Fast Strobe, Medium, Low, Slow Strobe, SOS."

Those modes are just madness, the lack of memory makes it even worse.

Greg, if you have any control over the drivers make them change to a more sensible order. One strobe is to many for a lot of people, but two and the totally useless SOS is just too much. It's a shame to ruin what is obviously a nicely built light with a terrible driver.

I actually love the mode sequence. I want to start off on high and if someone is coming at me hit them with the fast strobe. My nephew lives up in LA not too far from the hood and he has strobed a few gang fights at a distance and they scatter. One thing I always notice is that some people like the memory, some don't like the memory, some like the order of the modes, some want a different order, etc.

I will have some made up with memory, in case someone wants to start off on a certain mode. Since I like the order of the modes I will not pursue a change but having the memory mode should satisfy the people who want to start off in a certain mode.

It takes about 10 milliseconds to change from mode to mode anyway with a half tap of the button, there is no counterintuitive holding it down, then double tap, or whatever that some other lights do.

Thanks.

Greg

Thanks Greg,

My M3-2I is carried in a coat pocket and it has inadvertently been turned on during several occasions. Please send me the non-protruding switch cap to rectify the annoyance and I'll also add it to the review.

Ah yes. I was thinking that the mode sequence could be handy for law enforcement/military actually.

Will do. I've been ordering about a 20% ratio of non-portruding switches as that is about the demand. Most people, as myself, like the anti-roll switch with the easy press button. Really nice if you want to lay it on your car or something and point it at an area where you are working. It puts out an insane amount of light so I have actually used it to do night yard work in lieu of those huge construction plug in lights.

Thanks,

Greg
