MomentumExchange's 'BEAST-DRIVER' MODIFIED TRUSTFIRE TR-J12 BEAMSHOTS!!

Greetings all Smile

I have modified my Trustfire TR-J12 with this driver: http://www.kaidomain.com/Product/Details.S020417 which has increased the power from a fairly decent 27W, 2350 lumen OTF (reported) to a totally staggering 50-60W, 4000 lumen OTF (again reported, perhaps slightly less) for less than $20.

This has to be the cheapest 4000 lumfen light out there, for less than $90 (now less than $65!) ALL-IN (the TR-J12 is available here http://www.aliexpress.com/product-fm/546607503-Free-shipping-TrustFire-TR-J12-5-Cree-XML-T6-5-Mode-5xT6-SMO-Reflector-Led-Flashlight-wholesalers.html). The amount of light pumped out of this thing is just astounding, and it has great spill and throw. I have little to no mechanical, electrical or technical know-how (just a little intuition and a soldering iron…) so this is something anybody is capable of. 

I have taken a series of beamshots at ISO1600, F3.5, 1/10sec using a tripod. If there is anything else you’d like to know about this light or how I modified it, just ask! I do not, however, have any technical equipment so I can’t take tailcap or light level readings. I’m open to suggestions for other beamshots too Smile

 

So without further ado, happy viewing…….

Be warned: as I say, I am a complete novice so took literally no effort in making the insides look pretty, they just don’t. The soldering is, however, properly done and the connections are all reliable. This post is just to offer some idea of what to expect if you try this yourself (and do a neater job!) and I’ve included a circuit diagram of the driver in case the two boards need to be reconnected. All I am interested in, really, is that it works as it should which it does.. what more can you ask?

So…

The old driver removed with a drill:

The Beast Driver:

The installed Beast Driver
(yes I know it’s a total mess… no solder between the edge of the driver and the contact ring… glue everywhere… an uneven filing job and a messy blob of copper braid and solder as a contact but the fact of the matter is: IT DOES THE DAMN JOB!!)

I somehow separated the driver boards whilst filing them down to fit in the torch, so KaiDomain kindly sent me a diagram of how to rewire it! (obviously it’s red to red and blue to blue)

I can say your soldering is better than mine. Of course that doesn't say much. Silly

Wow is right!! I might need to add this light and driver to the list of must gets. Sure would love to see direct comparison photos with stock as well as hard numbers. With these results I’m sure it won’t be long until it happens. Great job!!!

imagine 9 led driver on x100 FUUUUU, I soldered for the first time when i changed the driver of my DRY few weeks ago. But i think I’m going to wait now with buying lights until there is a LED flashlight with 10k lumen or more in a compact format :d For now my 6000 lumen HID will have to do it, but it must be awesome to have full power immediately.

Wow, that is incredibly bright. For some reason glue wasn’t used on the J12 I recently received and comes apart no problem. I’ve received the Kadomain driver 3 mode driver and the custom mode version from them too. I just have to figure out how to solder a spring to the drivers +B before I try to install it. I don’t think my soldering iron will get hot enough to solder a heavy duty gold plated spring to it correctly. Nice photos, thanks for posting them.

I feel I should add these photos were taken with 3x SenyBor High Drain 18650s 2800mah in the torch. Haven’t had a chance to test the runtime in high mode (not sure if I want to because there is a lot of heat) but in the other modes it seems good (think 50% = 100% on the regular TR-J12 perhaps). I’d be keen to know which 26650s work best – A123s?

Thanks for your kind words

the black plastic element that is shown on dx has to be removed before you install the driver i guess?

Thanks for sharing this. And no worries about the solder skills. We are NOT all electronic whizzez. In fact a lot of us just do it because it means more lumens or less flashy modes or another emitter type or tint.

One quick question though. Just before you drilled through that driver the first time, did you stop to think something along the line of
“Whoa boy – what am I getting in to?” I know I would.

I love what you have done to this light. It really takes it to a new level.
Another question is this. Would you say that high mode with the old driver is ~ the same as 50% on the new one?
Just asking because then it seems you can have a nice long runtime with nice cool temperature at 50% and then still have the WHAM! effect of going full tilt. And THAT is close to having your cake and eating it too Wink

I’d say 50% on the modded TR-J12 is about equal to 100% on the old one, and yes it runs nice and cool on this setting. The modes are actually 100%, 75%, 50%, 35%, 5% and there is absolutely NO visible flicker (PWM) at all or flashy modes – something custom added for this driver by someone elsewhere on this site (if I find I will credit!) The 5% mode is even lower than the low mode on the original torch, so the beast driver really is better in every way.

And yes… it was a bit of a vertigo-type experience starting out blind but hey, someone’s gotta do it!

Nice….

Can’t wait for the 9 XM-L version to come out and someone tries the 9-LED KD driver. But i think even for the 7-LEDs the components were overheating and power was throttling down by 30 seconds or so.

mate i say well done thats what the manufactured suppose to do before the rated china lumens!!. i am waiting for my tr-j12 from allied express i got it for 45 $ lol!! + 20$ driver so 64$ = 4000 lumens !! THIS HAS GOTTA BE THE BEST BANG FOR BUCK RIGHT ?!!!

excuseme mister glow in the dark signature rings ? if i may size 37mm x 1mm or 36 × 1.5mm?? thanks for my J12 Big Smile

weird i just get addicted to flashlight like in a blink of an eye.

WOW!!! thats just NUTS. I love my TR-J12, such a great light. This mod takes it to BEAST MODE… Vernon Davis BEAST MODE ON!!!

Oh also one more thing… I melted+annealed my springs with the stock ~29W driver. A solder braid mod is a MUST with this ~55W driver.
Nice job and thanks for posting this!

That’s cheap. Cheapest i have seen on aliexpress was 50 bucks.

I got the X100 for $119. Charger (useless but well i’ll keep it), 4 x Trustfire 26650 protected which is a $44 dollar value and so the light is $75. Not too bad.
I can use the 26650 for my J12, JM05 and JM07. I feel safer than using the KKs.

The X100 should be able to do 3800L OTF stock with 2 cells. (assisted by 1 dummy via PVC 18650 sleeve stuffed w foil). The J12 tube does not fit the X100, confirmed by bro dong of thaicpf/flaslightmania.

I got my X100 from them, and their J12 is 50 bucks shipped.

That is insane! What’s the heat management like on high? The output is mind blowing, but the body doesn’t look like it’s made to handle such high temperatures and looks like it could do a bit of cooking!

Oh! I see you already answered that while I was typing. But then you answered it – Again. Wink
Thank you for the answers. Just what I was hoping for. And what a deal some of you guys have made on this light. Sweet!

It made me finally order the similar 7-led beast driver for my Keygos. Let's see how it performs..  J)

Be careful. Its 70W for the initial 30s or some before kickdown on the driver due to thermals. Might just burn the LEDs ont he J18 and similar. As you can see the X100 is much chunkier. Usually dong’s temp starts at 30 deg C or so. (Bangkok)

Slewflash – on high it heats up pretty fast, becoming very hot to the touch at around 5-6 minutes. The fins around the driver section get hot first, but pretty quickly the heat travels down the handle. The reflector is a huge chunk of aluminium screwed into the body, so I’d have to say the torch handles heat pretty well. I’m yet to experience the driver throttling back due to being too hot.

Theres some OUTSTANDING thermal and power analysis on this driver in the TR-J12 in this thread here…
It starts out drawing 88W (!!) at 12.5Vin for the first ~60 seconds, then power consumption drops to 25-32W for the rest of the run.

News: Some direct comparison shots coming between the Modded TR-J12 and my other lights (none strictly comparable but a good guide nonetheless)

- Xtar WK21
- Warm White 5-Mode P60 Drop-in (from KaiDomain)
- Custom made 1-Mode Cold White 1500 Lumen P60 (the brightest single 18650 P60 in the world!!) – Hand made by vinhnguyen54 on CPF – Specially selected cold white XML-U2 directly bonded to a copper – 5.5A driver, used with AW IMR battery

Shots up in a few days..

I'm looking forward to your photos. Just remember that anything that burns up or blows up is replaceable (in the flashlight that is). I have just built a JM05 running 5 amps and keep a fire extinguisher handy. Seriously though very interesting.

It does that for the 5-LED driver too?!

I wonder why these drivers do such a thing, and the drop is it due to thermal regulation. Maybe someone can do that IR thermal scan on the components. Smile

88W is not good for 5 LEDs definitely, it is worse than the DRY plus the immediate thermal mass is still in the DRY league. Luckily there is no strobe function….. If there is then the LEDs could fail very fast. I killed 3 this way. (the one which started it all, Sky Ray SR3800, which in my copy with the DRY driver it has much lower resistance so can quite a bit more current than the DRY).

In the DRY, you might measure 4A at the tail in steady state modes, but in strobe it goes much higher. Seems like the batteries are not taxed and can provide much more current during the ON state. Of coz that’s the early 3-mode driver. Luckily this new 5-LED driver excluded the strobe mode, else it might be the same.

I am 99% sure all discussion and analysis in that thread was regarding the 5-LED driver in a modded TRJ12… at least no one indicated anything otherwise.

whats your run time on that mode or say even 75% mode ?

weird i just get addicted to flashlight like in a blink of an eye.

I have not used it for that long on 75% mode so I don’t know. I tend to use 50% or lower for long runtimes (- even 5% is adequate to be honest) and the ‘big boy modes’ (75-100% of course) for… ahem .. impressing people/dominating large areas/arousing attention from neighbours several houses away Wink

youve got me hooked, i just ordered a driver for my trj12 from KD

for $20 cant go wrong

for anyone interested edcplus is carrying 3.7ah 26650 cells for $15 a piece. A little expensive, but a good reliable us source. I picked up 3 for the new driver. They are rated at 10a discharge rate (20a max continuous)

i wonder if the 7led driver in the x100 would get too hot lol … someone is bound to try it

Would you mind keeping the wrong flashlight?
Best wish, May
