Side by side 4x26650 please.

Some more pics here.... I was thinking a short hand held tube + fanny pack mounted battery pack with a coiled cord.

Someone should try it. I would but I just won the pilotptk auction. :P

I checked, the shipping has two options. Economy for $101.63 and Standard for $131.83.

I just checked and I got quoted the exact same number.

Oh thought it was a US seller so didn't even bother to check, guess that's not a bargin then.

The description also states the head is 75mm not 98. They got the pics wrong though, so who really knows what to think....

Wow! I think it looks awesome :-)

I have no need for it but come on. That is the multi emitter XML light Darth Wader would buy! LOL

Well damn, just bought a TR-J12, this one will surely be on my radar for awhile though, if it gets to ~$75 I may snap one up, looks to be a BEAST.

That's a pretty long light to have a tail switch. This new Trustfire, like its predecessors are still limited to 7.5a regulated current.

Yea, I didn’t notice that at first, makes me a sad panda though.

I missed something. Why is 7.5 A no good?

Because it’s severely underdriving the LEDs. At 7 LEDs you would like to see 14 amps or more, 2A per LED, hell, even 10.5 for 1.5A per LED would be better, but at 7.5 for 7 LEDs you’re giving each just a little over an amp, almost pointless.

So this has the same brightness (lumen output) as the TR-J18? Which is commonly observed to have similar output to the J12, right?

The beam pattern would be different though. This one should throw farther than the J18 with deeper reflectors right?

That would be my assumption.

TR-J18 runs with 3*26650 or 3*18650. X100 runs with 4!

Oh yeah, I missed that, thanks. I thought the 7.5 A was battery current but I see now that it's "regulated" 7.5 A so it must be the LED current. Gee, if that 7.5 A figure is true, it's only pushing about 25 W into the LEDs. Some of the 3x XM-L lights are doing 30 W or more already, so what would be the point in manufacturing this huge light driven at only 25 W?

I hope the 7.5 is a typo. Or, if the 7.5 A turns out to be the battery current, now we're talking...

7.5 A x 4 x 3.5 V (approx. battery voltage under load) = 105 W

driver efficiency = 80% approx. ==> 84 W reaching LEDs.

12 W per LED ==> about 3.5 A per LED. That would be awesome but the light would get stinkin' hot, fast.
