the newest craziness 9x XM-L U2

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.

what I see:

4-6-9 * 18650锂离子电池或4-6-9 * 17650锂离子电池或8-12-18 * CR123A或2-3*C(26650)锂离子电池或2-3*D(32650)锂离子电池,使用加长筒(另购)时可达3D锂或9*18650等电池。

with google translator:

Or 4-6-9 * 18650 lithium-ion battery or 4-6-9* 17650 lithium-ion battery or 8-12-18 * CR123A or 2-3 * C (26 650) Lithium-ion batteries or 2-3 * D (32650)lithium-ion battery, plus long-barreled (optional) up to a 3D lithium or 9 * 18650 battery.

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?

That's a $200+ 'pill.'

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.

My thoughts exactly!

You just said it better.

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....

Cracked me up

yes, please

ok, I can't afford it - 109 xb-d though?

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.

Flashlight nirvana. Wish Taobao had an English setup.

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.

they are representing the different models in their pics - frankly a 3 or 4 banger would work for me

  • 灰色/XML-T6*5
  • 灰色/XML-T6*7
  • 灰色/XML-T6*9
  • 灰色/XML-U2*5
  • 灰色/XML-U2*7
  • 灰色/XML-U2*9

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.

Oops. I need to work on my chinese.

is the beamshot of the sr92 with it on low or something?!

It's from this company : http://feilong.us/

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.
