Maxtoch XSWORD L2K - another laser thrower

Stumbled onto this earlier – http://www.maxtoch.com/xsword-l2k-2000-meters-ultra-thrower-p00065p1.html

Looks like laser lights are going to be the new thing for throwers now another manufacturer has joined in.

Very little out there regarding this light at the moment, not a clue how much it costs but it’s certainly got my interest up even if just to see how the technology develops.

500 lumens. Thumbs Up
And aspheric again.
I got a hunch that lens might be a better pick than a reflector for some reason.

ADDED:
Runs for 2 hours on a pair of 18650 batteries. That’s 11 W average power consumption. 45 lm/W. Suspiciously high…
ADDED2: 55 lm/W at low.

500 lumens is definitely more imterestimg than Acebeams 200 lumen. But why is the bram green? Yuck! Sick

Because they have the green filter on it for those beemahots.

Always remember SPC Joey Riley, KIA 11/24/14.

How is Maxtoch’s brand overall quality? Are they more of a budget or high end brand? I like their “shooter” models, but never bought one.

Maxtoch is a very under-rated brand. I have one and you’ll be surprised its quality and workmanship is at least at par, if not better, than the other major brands.

From what I’ve seen about this the regular beam is very warm tinted.

It’s great to see another LEP light.

I have a Maxtoch 2X shooter, the craftsmanship is great for the price.

Why dont they use for example XPL-HI, or XHP35 emitters instead of the older ones? If the shooter was made with 35-HI, 2000+ lumens, i would consider buying one. Also are there any deals on this brand? I see them listed only on Ali.

There was a model with xpl hi, M12 I think it was, I picked it up on a group buy last year

Edit-this is it http://maxtoch.com/mission-m12-xp-l-hi-p00049p1.html

I read that entire web page top to bottom, twice, and never saw any reference to a laser source, nor any reference at all to what actually powers it. Latest focusing BEAM using a military grade aspheric with dual side coatings, but no mention at all of laser or LED.

Interesting.

Some more calculations…
2000 m throw = 1 Mcd.
60 mm head, let’s assume 56 mm lens diameter. It needs emitter with 500+ cd/mm² to throw so far.
Even Blackie with collar won’t give you that.
From memory, the emitter that supposedly Acebeam uses does 400 cd/mm².

This may be another indication of somewhat inflated performance.
What is track record of Maxtoch when it comes to delivering the promised numbers?

I have the blf edition. Pretty true to spec i would say

Words can be broken,

The Black Flat should get up to around 540cd/mm^2 with the collar, but only with perfect heatsinking. You also need more than 11W, maybe around 16-18W.

All the speculation, so funny. I’ve had a sliced SST-40 doing over 1Mcd…

Agro? How do you establish 11W consumption? They do state that they use a pair of 3500mAh cells, but they do not state what the emitter is or if it’s a laser, so how do you know what voltage the light is operating under? Just curious… 2 hours on 8.4V at 3500mAh would, I guess, be about 1750mA per hour at 8.4V supply… after that I’m lost. lol

A high capacity cell 12 Wh at super-low currents and 11 Wh at higher ones. So we have 22 Wh consumption over 2 hours.

Note that it’s average consumption. The light may not be able to deliver full output all the way until battery is discharged. So it may use more power at peak output.

You are absolutely right, no reference to a laser source but considering the performance + “newest focus beam source” (as it is said in its description) = great chance that it is a LEP indeed.

But the “focus” woud be in the aspheric lens, and it says it uses a Military Grade aspheric with dual AR coatings. Wondering why they didn’t specify? I have spoken with a rep there multiple times over the years, I sent her a message asking about it…

Hmmmm, considering that I have a light I built from scratch that makes 1685M throw from an XP-L HI I’m not reading laser in those statements. Mine isn’t even an aspheric lens. Not saying it isn’t a laser, just not assuming anything. Difficult enough to decipher the Chinese claims from what they actually say, not gonna start trying to guess anything from what they DIDN’T say! lol

I won’t be surprised if the Maxtoch XSWORD L2K is made like the The Acebeam W10 (review) which uses a LEP + convex lens

Wow. LEP is crazy looking Big Smile

cd/mm2 is not really a unit. lm/mm2 is. Knowing how many lumens per mm2 an emitter gives off tells you how focused it is/how easy it is to focus.

cd/mm2 on the led makes no sense because the candela doesn’t depend only on the led. It depends on the rest of the light as well.

EDIT: 50% of the time I’m right every time.

Actually luminance [cd/mm^2] is a unit. It’s also the only unit related to light that the human eye can actuall determine. Lumens and lux cannot be accurately determined by the human eye (only by comparison to another light source). Luminance is how bright a light source looks when you look directly into it (for example the sun has a very high luminance).

Is this your opinion of the established unit of luminance (cd/mm^2)?

Luminance of a bare die does make sense. A 4 mm^2 die with 200 cd/mm^2 would have 800cd above it.

I am apparently misinformed. Sorry about that.

That said, I don’t think we are using cd/mm2 correctly here. I’m gonna read over the wikipedia page a few times.

EDIT: I see. cd/mm2 is directly related to lm/mm2, but it’s more useful because it can also be used for domed leds, for example. Am I right?

Luminance is the intensity of a light source. It is the same from any angle.

If you multiply it with pi (3.14) you get very close to the lumens/mm^2.

We are using it correctly. No need to check. Check out Endermans calculators. They will show you how it all comes together.
