What the hell? :)
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.

This is going to get floody...

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.

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.
