Maxtoch XSWORD L2K // 2000 Meter Laser Tech Thrower // Full Review

Recoil function? But yes… Everything in your tear down looks like high quality stuff :+1:

I am still not sure how it focuses the light… It will be very intersting to discover new things with this light. You are very lucky guys… Especially Dale cause he is serious modding expert and he does not fell sorry for 300$ light :beer:

Edit:

I just saw that prism pic… Holly …. ??? Alien technology ? :slight_smile:

Good review Robo…

We tested the new Xsword here in NZ - made my lux meter boggle and in the field and it certainly has huge distance. Found its not suited for our purposes as a hunter light however - beam simply too narrow for scanning terrain. Narrow and sharp enough to spot a gnat’s testicles at 700 yards - but we just don’t shoot alot of gnats!! Maxtoch 2X alot better as all-purpose outdoors/hunter light. Good to see Dale has pulled it down - we weren’t prepared to rip it apart - yet.

Will be interested to hear of possible mods. Maxtoch noted it is set at 2 degrees, and at 3 will deliver wider beam somewhat like 2X, but with 1000 lumens less. Didn’t break the Xsword down or pursue this explanation to see precisely what was meant - but modification to the laser/phosphor die config is evidently possible.

Robo - progress now with next Maxtoch design :slight_smile: - going in right direction. Email coming…

Yes it is a tight beam and I can see where a larger area is wanted for scanning larger areas when out hunting. As far as on target light the Xsword is hard to beat though with the 2 miles of throw it has and the low amperage draw.

Still amazing to me with such low lumens and low amperage just how far this light can reach.

I hope to see Maxtoch keep developing the great lights for the future as we have seen from them in the past.

And yes the 2X is still one of my favorite lights.

As it turns out, the double aspheric is a high quality molded plastic lens of some sort…

Y’all aren’t going to believe this. I saw it happen, measured it out, double and triple checked it, and I don’t believe it.

At a measured 50 Meters, this XSword makes 1.975Mcd for 2810.694M throw! That’s 3073.81 yards! Or effectively 1.75 miles throw! And now, the crazy part. It’s raining! I’m talking a thick heavy mist driven sideways by a biting North wind! Blizzard if it was 12 degrees colder!

1.975Mcd in a driven rain! This thing is insane!

Meter at x10, showing 79, at a measured 50M distance. That’s 790x2500. AmIrightoramIright?

It is basically a cheaper way of getting light collimated without a proper plano-aspheric lens.
Better than a spherical lens but worse than an aspheric.
Meant for focusing the light at a distant point rather than collimating to infinity.

It is the same thing except not in a compact package, they are using a separate laser, phosphor, and laser sink.

The thing on the glass is a 45 degree mirror which directs any leaking blue laser light off the the side and into the flashlight head.
The laser is behind the phosphor, you can’t see it.
The 45 degree mirror is there to prevent blinding people.

Do you think it looks like this basic design where the laser is firing at the phosphor from behind?

Since some of the laser light might be traveling through the phosphor (maybe blue or UV light) they added a 45° mirror on the opposite side as the laser to direct that light to the side?

How wide is the beam without the main lens? Does some light hit the inside of the light? I want to find out how similar the radiation pattern is to a LED.

Dale told me last night that without the lens in the light it makes a super wide floody light on the ceiling about like a regular emitter does , with a big shadow in the center from the mirror that is mounted on the glass in the laser housing. It sounds like all the focusing is coming from that double aspheric lens they have designed for this light really.

Thinking about this 1.9Mcd throw…
I may have missed the exact number but I estimate the effective lens opening at 55m diameter. Say I want 300 kcd instaed of 1900 kcd (300 kcd is my favorite throw number :slight_smile: ), in theory I should achieve that with the same flashlight with a lens with 6.3 times less surface area, so a mere 22mm diameter lens should do the job, that is the front opening of a Emisar D4. The mirror in the light path will probably block a somewhat higher percentage with a smaller lens, so maybe 25mm is needed for 300 kcd.
The Weltool W3 has a front opening that is about 25mm (bit more even so it looks) but achieves only 180 kcd. Sounds like I have to wait for a better version in this size then :slight_smile:

So it should be comfortably over 2.0 Mcd in excellent conditions.

I’m sorry, but the straight up is that I’m a dumb ass. Forgetful as the day is long. That high number bugged me throughout the night, around 2 AM I figured it out. I forgot to turn my headlamp off. It should be embarrassing but I’m forgetful for health reasons and it is what it is.

So, 6 AM this morning finds me back out in the cold rain, doing it all over again… without the headlight.

1.3Mcd is the real lux number at 50M. Still raining lightly.

Again, my bad, sorry about that.

Still not a bad number at 50 meters………I had the 1.8Mcd indoors at 10 meters with my sample.

520x2500=1300000 for 2280.35M throw. Or 1.4169 miles in the rain. (I’m sure the rain would block it more out further)

Right Jason, I can see it being set up like that, it would also explain why the mirror is slightly off center on mine… that lay-out explains that set-up quite nicely.

I didn’t remove this pcb but maybe I should have, the laser is almost certainly under here…

Thanks for the 6AM update Dale, your dedication to the hobby is undiminished! :smiley:
That places the Weltool in the same efficiency-class as the Maxtoch after all.

Jos, actual lens opening is 53.4mm. :wink:

Thanks, that enables quite accurate calculation of the gain of this LEP module compared to a Black Flat, in real flashlights, assuming that Maxtoch optimised the LEP module for todays standards. Maybe later we find out how to overdrive the blue laser for a fast and short LEP life :smiling_imp:

With the Black Flat in a rough B158 mod (47mm lens) I got 350 kcd, but with some sorting and optimising people should be able to get 390 kcd. Correction to a 53.4mm lens would give 503 kcd. So this LEP technology gives 2.6 times as much spot brightness as the best current overdriven flashlight build. A wavien collar can increase the luminance of the die 2.2 times, so with one, a led actually comes pretty close to a LEP module. I wonder what the upcoming HX Boost led achieves with a collar…

why don’t make white laser( 3 RGB laser combined), the beam will be super tiny and super bright, but it will give ridiculous throw

Pretty simple and obvious question with a very complicated and not so obvious answer.

To get white light, equal parts of the color spectrum are mixed. Output from lasers is very distinct, a particular wavelength, but to control the effective output is perhaps more complicated than it would seem. Easy to put out a large amount of green light, not at all easy to produce an equal amount of red light, and blue is also not easy to make the output match green. The resulting mix of color, IF the outputs are matched through a great deal of effort, is not the white light you would want to use as a “flashlight” because of the 3 specific wavelengths mixed instead of an equal amount of all light.

And then of course there’s the radiation, the part that is damaging to animals (human’s are animals too of course!)

So, level of difficulty, expense, and dangerous output are the 3 primary reasons it’s not done.

(This is of course my take on the subject, accuracy may deviate from actual truth based on factors beyond my control, ie: how fast have I drank this mornings coffee…)
