XTAR S1 looks nice, but the price will be right up there i think, i rather some thing a bit cheaper to knock around.
I plan to mod this TR-J12 with 2 drivers from DX or KD.
1 for 3*XM-L in row, another for both side.
With 3*26650 I can get 2.7-2.8A per LED

Hi Pok, this is like the DRY driver (I have lots of them!). 3 in series is ok. How do you plan to wire the other 2 LEDs? You cannot use another of these to power the 2 LEDs at 9V.
With 3 x 26650, this light would be very efficient and you will get 2000 lumens OTF at least. The original ver 0 of Sky Ray 3800 you can get 1600L OTF, but it cannot be sustained I mean it can do that but the driver will fry eventually.
The DRY would not fry, just that it gets too hot and eventually will too. But generally reliability is fine.
Need to get the light first and examine it. Hope the driver can stand up to heat. This seems to be driving each XM-L at 1.5 amps. Not sure is it in series or parallel. With 3 of King Kong 26650, you can do slightly over 2hours at 2000 lumens OTF with no issue of overheating.
We need to know if the leds are in series or parallel first, even the TR-3T6 with a couple of resolders should throw out 2700 otf,s but for how long is the question.
I did that, DD. no issue. Strobe with the DRY driver killed one of the LEDs in my SR3800 (replacement 16mm coming from dinodirect, $8 only!). Looks like strobe is very hard, maybe the cell can recover during that brief OFF period and when it comes on it whacks the XM-L silly......do this a couple of times and it goes POOF. That is why i told people not to operate the DRY with fully charged cells, let it drop a bit to 4.1V at least and the light would serve you for a long time. My best cells, the Sanyo 2600 (better than my NCR18650 and NCR18650A) would have absolutely no issue POOFing XM-Ls when fully charged, they are like near IMRs in terms of current delivery.
Strobe is realy hard on led,s and jsut about every thing electical, not to mention your eyes, still not sure why they insist on selling lights with strobe.
Remember that this driver is up to 18V with no memory mode.
Both 2 drivers power with 3*26650 and always start in low mode when you switch on.
Sorry for my bad English I can't explan well.
Nice! I think they just raised the bar with this one. Pity about the price though, although the per-lumen or per-emitter price is still reasonable.
Maybe one problem, How can I put 2 drivers in bezel 
Pok, thanks for trying to explain. Maybe someone like E1320, mitro, dopmuller, boaz can figure it out.... If it's 6 x XM-L then that's very easy, as long as there is space inside.
sb56637, this works out to be usd16.6 per XM-L for the aliexpress store at usd83. For this light at 75mm diameter and slightly bigger body tube, there is quiet a lot of aluminum too. The tube is pretty thick. I think it is easily 500g.
Interesting, this is only 63mm HD and the Sky Ray L1 is 74mm. On Kaidomain you can see the SR L1 to have the reflectors not extending to the edge, while this TR-J12 got reflectors all the way to the edge.
Someone listened to us!!! Whats up with the 72000mA drive rating lol??
It is good they have moved away from the TR-500, 600, 800, 1200, 1600 and TR-3T6 hosts but they would of had to for 5 x XM-L's.
Run time with 3 x 26650 4000 mAh batteries should be decent and with all that alloy and fins it should do well for heat, ill be intrested if they stayed with the style of the TR-3T6 screw in as I thought that was great.
Price for 5 x T6 emmiters and a new designed host is not to bad, but it is getting up there for budget lights, on first impressions I'm keen.
Vaporware or a prototype. Look at the blurred out host and terrible pics. I don't trust this one bit.
Rich
I agree with Rich about the first pic. It's a bad 'chop.
The other pics from the site look legit.
The 72-amp rating looks to be a decimal point off.
I'm partial to single-cell lights, but this light is just too tempting. Can't wait to get it. :)
I don't think it's blurred out or it's a prototype. I mentioned that there is even a nice instruction manual printed for it. MAybe you missed my link, but the cuttings and flashlight seems high in quality (at least in the budget lights realm).
And with ESCROW, payment is not released to the seller until you "press the button" after you have the item in your hands and inspected it. You do not pay first, the money is with ESCROW and if there is an issue, you can raise a claim. There is also an Ebay style rating system.
I have purchased 38 items from Aliexpress, if the item is bad, you negotiate with the seller, the psychological advantage is on your side. I think cd520 also used it before, unfortunately USPS lost his parcel when DHL handed it to USPS for the last leg to his house. *shucks!* At least on paper for this Aliexpress store, if sometime goes wrong witinh 15 days, they would pay for the return shipping. I do not think anybody from GG, Illumination Supply, etc any store selling even a $300 branded light in the USA has such a policy. In the past, i have made use of this for 1 time as in return shipping is paid by the dealer, but that's another HK dealer.
It's 7.5A maximum output current. I guess that is 1.5A to each LED. Check out the instruction sheet on Emmy Zhang's Aliexpress site.
Aliexpress say 7.5 amp max.
Kd say its a 7.2 amp max.
going from KD it works out around 1.4 amp to the each emitter aprox 2600 out the front lumens, if there is no boost circut in the driver, it still should hurt the old eyes on high when you first turn it on.
Ill wait for manafont and see what they say, but even if its well under driven around 1.4 amps x 5 it will put out a huge amount of light.
Bro, it should be read as, the Trustfire instruction sheet as photographed by the Aliexpress website reads as 7.5 amps. It probably is the same as SPAMBOT's Sky Ray L1 drive levels. You have the TR-1200 which i believe is the well driven earlier copies that came out initially, some others copies report a 1A drive level only for the later batches. MF sells a "1.5A per LED" driver, so you can change that out for the under-driven TR1200s. BTW, 1.5A XR-E R2 and 1.5A T6 is a heck lot of difference coz above 1.1A there really is not much meat left for R2. :)
I trust you guys' readings much more.
you should not drive an R2 or Q5 higher then 1 amp, the emitters are only rated for 1 amp.
