TrustFire TR-J12 5*CREE XML T6 from DX MF and KD

The LEDs are in series. All of these multi-emitter/multi-cell lights are. (OOPS - wrong) However, you assumption that they came up with 7.5A from 1.5A per emitter is still probably right. The specs just aren’t quite accurate. It WOULD be 7.5A if it was driven with a single cell. :stuck_out_tongue:

EDIT: I think we're looking at about 3A on 2 fully charged cells and 2A on 3 cells.

EDIT AGAIN: Where are my manners? Welcome to BLF!

Thanks :-), ok I'll measure both tail cap pull and lux meter and compare it to my other lights when it arrives :-) will try both with 26650s and 18650s, let's hope this a good quality light. My other Trustfires has been of very nice quality.

I thought the TR-3T6 was wired in series i swore it was ? but later on some one posted a picture of the emitters wired in parrallel on my thread ?

Hello and welcome.

Call me crazy i like the brand trustfire and all my multi cell trustfire lights are very well driven and regulated with good heat sinking

I haven’t seen that! Can you point me to the pic?

EDIT: Nevermind. I saw the discussion in the other thread. You learn something everyday.

Yeah i hear ya, so if the TR-3T6 has a 3 amp driver ( not saying it puts all that to the led,s ) and its wired in parrallel, it could be slightly possible the TR-J12 could be 7.5 amps wired in parrallel in a perfect world.

POsted in the other thread, but lets write them here again:

Trustfire TR 3T6 has the leds wired in parallel. The driver is a buck regulator of 4,7amp that is the same from trustfire x7 and other sst50 led flashlights. OUtputs about 1600 OTF, this is why it can perform from 2 or 3 18650 batteries. If it was a boost driver, it had to be a buck/boost converter, very very expensive and even good flashlights don't have it!!

This one, i am guessing it has 5 leds wired too in parallel. A new boost 1,5amp driver will cost too much. So ,they use an old, it is a 7,5amp buck regulator(they give this rating already) for all the leds. It is a driver that comes from other sst90 flashlights. I am expecting 2000 OTF, i ordered one too from KD.

good info thanks

The Fryray 3800 had a boost 1.5A driver, but we all know how well that worked out. :p Thanks for teaching me something today, guys.

I'm still excited to get the J12. :)

When there are 6 x XM-Ls in the market, give me a call and i'll shoe-horn 2 x DRY drivers in there and 6 IMRs into the tube and then take cover....thanks!

Seriously the modders have done it like the beginning of the year with even 6 emitters, how to drive 5 x XM-L with drivers properly right to the limit? (no DD pls)

<coughwatchspendingcough> LOL

I have a question ergotelis i thought we could not mix xm-l and sst drivers with diffrent emitters due to some thing to do with vf and voltage, i read it on here some where i tryed to find the thread with now joy.

So tr-3t6 has a sst-50 driver in it and they emitters are in pallel why cant we retro fit a sst-90 12 volt 9 amp driver and bump up the otf and depending on the screw-in drop-in for fix set up for the TR-j12 we could do the same.

p,s i have not looked up the sst90 data sheets

Me to but its the most costly light ive brought sofar and i know i dont need it lols

Ahh....so i guess can mod as parallel. Squeeze 1 SST-90 driver in there to drive 3 XM-Ls and 1 SST-50 driver in there to drive the remaining 2. The SST-50 driver must be able to take 12V though. But i guess high chance there is no space.

Yeah, i am excited too! It seems to be quite a good design for a "cheap" powerful flashlight!

No worries about the vF, the drivers are current regulated, for example, you can put two xm-l into series and the vf will be 6,7V and the amp still 4,7amp( i am not sure this driver will allow this, but i am guessing it will)

Swaping a 9amp driver is what i would like to do too! Of course it is possible as long as it fits! THough these drivers are still expensive enough, possibly a small mod in the existing driver might do the job to boost for a while the amperage.

Ordered a UCL lens too, i believe that this 72,7mm might fit. If not, i will trim it for my trustfire x6.

But to be sure, we have to wait for product to arrive, to open it and check it!

More high-res pictures at lightmalls. You can email them to specifically pick a copy that is flawless for you. They did that for my Uniquefire 3900, which really was literally flawless. I also asked the Aliexpress shop to do that for me, lets see if that is really true.

You can see the plastic disc and battery nipple for the head. Not a PCB and no sign of a spring. So that's a good sign, most probably not a drop-in!

I asked Ric (from cnqualitygoods) yesterday why he wasn"t selling the light..

Checked his website today and Tadaa:

http://www.cnqualitygoods.com/goods.php?id=1348

Reading this and the fact that Ric is planning a groupbuy for the DRY.. maybe he could do both ;)

ps, POK the link in your first post to the manafont website is wrong. It leads to a different light!

After a prompt conversation with the seller, asking if I needed batteries and stating protected batteries would be a must for this light I were more than happy with my choice. And after that my order from Aliexpress was dispatched in one day and with HongKong post as I requested. The tracking number was also sent with the shipping notification. I am now looking forward to getting this light in my hands.

Got myself protected Trustfre 26650 also. Thanks for the heads up guys. I guess I can stack a couple of King Kongs with one Protected Trustfire and get a decent short circuit protection, right? Though, nobody confirmed the cutting current of these protected 26650s yet.

I guess 1 Trustfire 26650 with protection does protect your other 1 or 2 unprotected cells like king kong in a dead short by a malfunctioning driver (worst case scenario). However still not recommended as the discharge would be mismatched, though i fail to see how the king kongs with so much capacity and current capability would be stressed. Not for the faint-hearted or those non-technically inclined.

3pcs of good 18650 like XTAR 2600s (nearly 2500mAh measured for cycled cells) are good enough and the slightly fatter tube does make the proportions better and more balanced, and very slightly enhances heat disspation as well compared to a 2 cell thin tubed flashlight designed for 18650s.

Of course. I’m just trying to minimize the risk while trying to keep my new King Kongs in circuit. I guess Trustfire’s would drop earlier so wouldn’t stress KingKongs with low voltage. Both were measured above 4000Mah while TFs are said to be more like 4000 and KKs 4500.

Ok, I'm in. My new years resolution for 2012 is to only buy neutral/warm, non blinky, 3-mode lights. So I figured I better get one more unrestrained purchase in before the big blinky ball descends.

I just wish Manafont carried 26650s.
