What the hell?  Smile
I'm curious how ugly is the beam pattern, but no doubt, it's a monster.

Interesting method of LED placement.

I want that host badly.

Wonder how much smoke it will produce? And how long it takes to explode. Sounds more like some sort of grenade than a light.

 

27A for 9XM-L in parallel. What sort of cell can handle that? Not anything that'll fit in the 280mm length. Google Translate didn't help much here. At most it is long enough for 3x18650 in series. Which means 8A each from them! Better use good IMR's.

 

27V at 3A in series. Which would mean 7-8x18650.

 

If these are driven hard which I doubt this is an 80W device!

 

And if I read it right that's a US$450 device. Probably double that from the usual free shipping suspects.

 

The numbers from my light tests are always to be found here.

What a monster!!

 

I think I would go for HID instead for such power consumption, I do not feel those XM-L will last too much being so close to each other.

I am not sure, but the same seller has this pill, with 4*SST-90 on a CSM360 module, I am not sure it is compatible with the same host, but it should also generate quite a lot of heat for winter.

While that current draw would be extreme for typical 18650s, for a 4000mAh 26650, it's only 2C - well within most published specs.

For comparison, that's similar to the load placed on a typical 14500 by a well-driven XP-G, or a triple XM-L run at 3A with 2-cells.

 

 

At this rate, the XM-L is going to become this generation's 5mm LED - 109 XM-L 'showerhead,' anyone?

80 watts . . . 9 x XM-L in parallel . . . yowser!  Also, that 4 x SST-90 pill looks awesome.

I must say; judging from this, these guys seem like true flashaholics . . . . with no fear of the after-life.

The 9 leds will operate at 12v.

Get the two 9*U2 pill, solder it to a big copper heat-sink and you may have a headlight....

Will it melt the Nerf gun it is going to get mounted to?  I need to know because my kids like to accessorize like their big boy heros.

Anyone else notice each picture appears to be a different light? 1 with 5 leds and 1 with 7 leds and 1 with a smooth reflector. Seems almost light bad photoshopping or something.

There are three different lights for sale, in 5-, 7-, and 9-XM-L configuration.

9 XM-L's in, what, a square inch?  Yeah.  Good luck with that.  Unless they found some super-metal to use as the pill, it will be so freakin hot in about 13 seconds that the XM-Ls will burst into flames.  In my light with 24 XM-L's, I had to add 4 pounds of aluminum with more than 450 sq. inches of surface area to even think about controlling the heat produced - and they're far more spaced out.  Back of the napkin calculations suggest that 80 or 90 watts into 2 cubic inches of copper would yield a steady state temperature of about 300C - some heat is going to be dissipated by convection through the host, but I would still suspect 200+ C.  I know I don't want that thing in my hand.

When LED's are 80% efficient rather than 10%, That will make a kick-ass-host.  For now, it's just not practical.

Oh....they said for the 9 XM-L model can use 3 x D sized 32650.  

From KD's smaller 32600 5000mAh, mitro did 4500mAh @ 5A (I measured 5200mAh @ 1A). The KK 26650 did 10A nicely. So I think battery requirement would be taxed but it's not impossible.  However it is non-protected, definitely not for the novices.

The light is the 2D80 model, 80mm++ head and 3D long.  So something like TK70 just smaller by 20mm. 1kg mass, 200g more than TK70.

9-XML must use 3x 32650 tube.  Not sure if it can do 3S3P 18650.

For the 7-XML and 5-XML models it can use  2D tube, or 2S3P 18650. 

 

It's 80mm reflector with somewhat spaced XM-Ls.  Hence it is still something like a floodlight, or think of it as slightly worse than 9 XM-Ls with individual reflectors squeezed inside.  From the beamshots, it still throws less than the SR92, and the SR92 has 45k cd.   It's damn bright (lumens) though.

 

PS. As always, never take the output specs at face value, someone tested the CSM-360 and was disappointed.

It's taxed real bad, but not that "mission impossible".

The problem with such a design is that it is not mounted on 14/16mm MCPCB like the DRY, TR-J12, usual triple XM-L suspects.  Take for eg the DRY, ignore the output but basically that is a 40W or 40W plus light depending on the amps that the cells can push.  It's mounted on a light weight host but the LEDs are on 14mm. 

Even with direct emitter bonding, it's too close. Overall efficiency would be like the DRY once past a certain point (eg it's 3A for the triple XM-Ls and it slides down significantly).  Even if the driver can take it, say instead of 8000 lumens theorectical, it probably might be 6500 lumens.  With that mounting the efficiency takes a heat as it's really different from individual 14mm MCPCB or slightly cut 16mm MCPCBs.

6000-6500 emitter lumens from 9 XM-Ls sounds doable in such a package - but then again it's too expensive.  2 x TR-J12 gives nearly 5000 lumens OTF and costs about usd160 shipped.

Note : 2 x TR-J12 has a total of 10 XM-Ls; 2 lights of 65mm head diameter each (so you can calculate total area).  It would have 48k cd, so it's same throw as the SR92.  this feilong has less throw than SR92.  I think the this 2D80 feilong light is not optimised in one way or another....

Super metal? Na... they use a super liquid, helium ll to be precise (I wish).

"The thermal conductivity of helium II is greater than that of any other known substance, a million times that of helium I and several hundred times that of copper" (Wikipedia) http://www.youtube.com/watch?v=2Z6UJbwxBZI

Nice... where can I get some?

One small problem with this theory.. Just touching a torch containing He-II would freeze your hand pretty quickly. If memory serves, Helium is only liquid at like 2K (2 Degrees C above absolute zero).  There also isn't a flashlight manufacturer on the planet that could design seals and threads capable of keeping liquid helium from leaking out.

Not to mention the heat would have nowhere to go :glasses:, darn it. Scientist need to hurry up and invent magic. (actually we do have it, but it is virtual Silly )

I don't find it to be a fair comparisson 2100, if you continue that way, you could say, 10 X UF-2100 will give you the same for 100USD.

This is a single light, there is no way to compare to two sepparate lights in my opinion.

Haha...you are right.  Someone did tell me to tape 3 x UF-2100s together to get a triple XM-L.  The UF-2100 is $14.50 cheapest from what i come across though, i like that thing with 4.7kHz PWM!

But this really is a floodlight. The truth is this....  Something is preventing it to be so far below SR92's 45k cd, coz even by sheer power as a floodlight, it should be able to do above 45k cd. Heck I got nearly 30k cd from the 54mm diameter Sky Ray 3800, DDed of course.

 I guess the spacing is a bit worse than typical budgetlights.  Take the above mentioned TR-J12 for example, it's 44k cd for 9 XM-Ls.  Area is 30cm^2 for TR-J12. Minusing off those area which are unused and it could be say 25cm^2?  It's actually about 460 lumens for each XM-L, it's not a flashlight which has its emitter gunned like there is no tomorrow. Eg, DRY.

Feilong is 8cm, or 50cm^2. And it has a whole single reflector. But it is noticeably less throwy than 45k cd. 

 

What I can think of is :

(1) Noticeably less lumens per emitter than even a TR-J12, low drive levels. Could be due to (a) driver unable to support those power, though they are "rated" - doesn't mean that they need to do that in reality  (b) battery cannot supply such juice. But not likely as you need only 10 amps for each 32650.  I have good experience with the 26650 and 32600, the 32600 happily does 4.5A and does not even get hot much and lose much capacity.

(1a) what I am afraid is that due to point 1, the lumens output is there also. That is logical.

(2) Heat is affecting the output even at lowered drive levels due to the emitters designed in a cluster. 

 

I actually have the XTAR S1 which is effectively a 85mm head diameter light and 3P battery config, and i have examined the driver space.  Not too much space there, but of course much better than the usual multi-XML lights that i have (quite a lot there). The TK70 is a 105mm class multi-XML light that accepts the same 32mm diameter cells, slightly better.  The thing is that heat output of the lights affects them driver electronics. You can drive them hard of course, but they won't last past a few minutes.  That said, the DRY 3 x XM-L is a different breed, it's a light for the lumen junkies, truly unlimited/unrestricted stuff.

I still can't find that CSM-360 by feilong tested by a Russian guy....they were saying there were some drive problems, just not driven hard enough and it's not that bright at all from the measurements.

 

Don't get me wrong, it's an interesting concept.  The modders have done dual emitter versions on a single reflector, so it's not new. MC-E is a quad, the very little known CSM-360 is a quad as well.  But 5/7/9 emitters is new and definitely "hauls ass". But perhaps it would be better if the neck is made bigger with more fins, and they use at least a 100mm reflector preferably 150mm, and make it as special edition.

Folks can get like 300k cd with 75mm with HIDs.
