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 :p )
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.
You may put the bezel face down, wrap legs and arms around the tube, have a friend punch it on high, and ride it to the moon! Light this candle, baby! Yeehah!
The CSM-360 with an aspheric will look like this:
I admit it, actually i wanted to get that feilong when i first got into the hobby!
The one I like most from that manufacturer is the flydragon, with an aspheric and also a regular reflector head, but it is far from a budget light I could assume to buy.
2100, I believe the problem of this huge thing is using a single reflector, surely one small reflector for each die would throw much better, but it would need a huge head..
De-focussing it a little bit to get all emitters on the same area should throw quite well, did anyone try it?
I really like aspherics, but even though it is impressive, I'm not fan of that beam profile.
defocusing would probably help a lot though
anyway, as for this 9xml - i can't figure out why they crammed the emitters together. if it is going to flood you might as well space them out in smaller reflectors like the current 3 and 5xmls.
That would also leave quite a cavern for adding more mass - although a 5 or 6 lb light is a little impractical (for most of my purposes anyway).
Yes Dthrckt, I agree with you 100%, but in the other hand it is good to see companies taking the risk of doing different models even if they are not that good :)
You want more pic - take a look at this forum (english translation link included):
agreed - I don't think it is that bad, actually. I mean, if you have the money to spend on lots of emitters, there's nothing wrong w/ underdriving xmls...
I don't care about the throw figures - if you wanted throw in a light this size you'd go HID, right?
let's hope they're reaching the point where they realize they'll have to begin to use some active cooling if they want to continue to push the envelope.
Yep, fei long in chinese is actually Fly Dragon directly translated. :)
I was hoping someone do some XR-Es in this bugger. Holy !@$!@#@ it'd be awesome. HIDs radiate quite a lot of heat via the front glass though. LEDs do not, it's via the back. LEDs hate heat, HIDs love heat. It is not until about 400W in a 7" portable host that do you need forced air cooling. Yeah, that is like WOW.
