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

Ships from Hong Kong

Trustfire 26650 5000mAh (4000mAh Real(!?)) : http://www.powerwholesale.net/trustfire-26650-5000mah-37v-liion-protected-battery2pcs-p-1663.html - 15 Bucks

They are real

DX has it for $22.80 for a pair

I also ordered mine from Aliexpress today and could luckily used a $5 discount coupon as this was my first order. You can search and fins some coupons for first orders >$50, $100 and $200 as well. It made the price ~$78 for me. The seller contacted me promptly and asked if I needed batteries and charger as well. Quite promising communications sofar.

I also ordered 3 pieces of King Kong batteries from Intl-Outdoors. I hope to have a super long life, super high power light at the end.

Manafont has 25500 type o ?

Add about 7-8 bucks for shipping.

Last year and this year, there were some threads on Bestinone.net and it's amongst one of the best sites around. Live chat works and the cells they do are very good. The best is the 18350s which many reported to significantly go over the stated capacity. My 18500 and 14500 can reach the stated capacity. Shao is selling them on CPFM. They have 3500mAh 26650s. Add $2 for shipping though. Unfortuantely you can't buy in 1 pc.

Bro, just to check, you know about Li-ion handling and safety right? One thing with unprotected batteries is never to leave it unattended. This is needed because quite a few would mention and want "super long life". When the light cuts, you need to run over quick to turn off the light via the tailcap. And i do mean fast within 5 seconds. Sometimes the driver components (usually MOSTFETs) burn out and cut out before that when it fails, so you are safe. Sometimes they flicker and you have early warning.

Oh...this is easy. I wanted to get the XTAR S1 and figured that i could save more with this TR-J12. hehe.... :D

Anyway, some videos of the Sky Ray L1. I think the hotspot of the L1 is a bit larger as well (other than it nets you 700+ lux compared to Trustfire's 500+) Disclaimer : It is just for your info. I cannot verify the accuracy of the tail readings. I repeat, this is for your reference and enjoyment only....

And in this vid, you can see that the 2-cell Sky Ray SR3800 with drop-in taking in quite lower readings at 1.8A. Usually we get like 2.6A with rev 0. And so you also get light that is similar to the Trustfire. My copy of SR3800 is much brighter than the Trustfire. It does not make sense though....2 cells at 1.8A and 3-cells at 1.5A but give off the same amount of light on the lux meter? Some variable is messing things up.

Hmm. Just made the calculation now. I guess you're right. When the voltage drops the current drawn from the cells will increase, but would it still go up to dangerous measures with 3x26650 cells really? I mean I won't push the light onhigh for long but might leave for 6 hours in the mid setting.

BTW, could anybody confirm if this light has under voltage protection for 2xcells? Maybe one who can read Chinese?

Oh actually that boost in current part is ok when the cell drains. I am talking more about driver failures, guess i did not mention that specifically in my post. When the driver fails, there is a high chance it would give a dead short, and most unprotected batteries don't like that and may vent after a good number of seconds. Only some Panasonics can hold up to dead shorts and what you get is a dead cell after that, no vents/explosions. I am talking about the safety part, not the dead equipment part.

Not sure if there is any LV cut and we cannot assume, need to test it out.

First post :-) I went on and ordered one. I guess the LEDs are in parallel since they claim 7,5A pull from driver, 7,5/5=1,5A each and should have about 2750 lumen total, am I correct?

On paper, 1500mA from the driver to each XM-L gives you a total of 2840 emitter lumens initially. Smile Still yet to determine the drive levels, could be the same with Fry Ray L1, could be different.

This gives 2000 OTF lumens, 25% hit by the reflector, 5% by the glass. That is a very conservative outlook. Same answer, need to measure.

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. :)
