Review TrustFire TR-3T6 Triple XM-L T6 5-Modes Memory LED Flashlight (3x18650)

Do you see the cutted trace? The upper part is the input pin of the current regulator.
If you solder a wire to the upper part and connect it to the positive pin of the controller it will give you full regulated current through the LEDs. No modes.
I haven’t tested it for more than 20 seconds but I could do it, I also could post a picture of a wire if you like to.

VCC I won’t do that anymore from now on I say V+ Or positive supply voltage.


If you want custom modes not just high it would be more complicated, I have some parts in progress(will take 3weeks at least)which will make it easier for everyone who can solder a bit.


If someone has a driver on which you still can read the writings on the IC please make a picture. Mine are all grinded away.

Edit:
This is how to make it one mode only:
Cut the trace of the Pwm signal and grind a bit of the green stop mask away:

Solder a wire on the grinded spot,or on the resistor which is a few mm above the cut. Make sure you don’t short something while doing it.
Solder the other end to this spot, it has +5V

The wire I used is a bit long and ugly(was just laying around), you should make it more clean.

A photo with the wires conected on the board would be the best explanation for that discasion.Photo would help much more…Thanks!!!

Ηι Werner, Thanks for the useful information, but could you please upload the photo with the conections again, because we cant’t see it?

Sorry. I am currently experimenting with dropbox for uploading my pictures. I am still unsure what happened. I am sure that the picture was visible after posting.

Hi, Werner
Could you please, reupload the photo to see the conection?

Thanks Werner,
Got the photo, I’m gonna test it right now.!!!

Wow.
Easy solution for the 3/5 modes of this driver.
Can we have the same result with the pencil&capacitor tweak?

Τι εννοείς?

I am curious to see your results gogo.

I guess the driver stores the mode permanent in his EEPROM, it never looses the last mode, at least it didn’t in the time I tried. you can try it too, maybe I am wrong.
So a faster discharge with a pencil won’t work. Also there are a lot capacitors on this driver which have different reasons so I will not investigate this further. This seems to be fairly easy too.

This mod is only to make it one mode always high.
If you want custom modes you can hang another controller on top of the driver, like I did. For example you can use a nanjg and simply solder the PWM pin on the right spot of the driver that’s what comfy and me are investigating right now with the srkdrivers…

P.S.: still waiting for the 64k :wink:

As far as good Werner, the flashlight works great with that mod. That was exacly what i was looking for.
Thanks Werner.

is there any fix for the nasty pwm on these drivers?

Wire another controller on the driver and use the modes and PWM from the new controller…

Reviving old thread!

I have one of these, it works fine on 3 battery setup. Last night I switched it to 2 battery mode and it wouldn’t work. Just flashed once when turned on. Admittedly using Shitfire blue batteries. They’re all at 4.1 volts.

Does a 2 battery setup draw more current to trip the protection circuit?

Yes I believe it will.

Of Course, if you use just two batteries the current will be higher.
If your batteryvoltage breaks further in at 2A the current increases even more and this can be too much for Garbage batteries, a kind of vicious cycle.
Check post 689 to See some measurements…

Hey guys just picked one of these up and looking for throw (yes I know it’s not a thrower). I am planning on either all XP-G2’s on copper or possible 2x XP-G2’s and 1 XP-E2 all dedomed. Do to think the addition of 1 XP-E2 would give it any additional throw? What about even switching it up and doing 2 E2’s and 1 G2 or even all E2’s? I could care less about about total output but I have set a goal of 100kcd, I got the driver covered just tell me what emitter setup to use.

Any thoughts?

For throw you would be better served with a different flashlight, a c8 with xpg for example…

I’m going to be adding in a .2. My board is the one with R100 200 250 already in place. Do I add the .2 ontop / of any of them or does it have to be a specific resistor? The most accessible is 200.

I am looking for the cheapest price i can find on at least four to six of these. (i have plans… :stuck_out_tongue:

Ok, so as above I have the driver with R100 200 250. I added an extra 200 in on top.

Standard tailcap with Shitfire - 1.8a (3 cells)
Modded tailcap with Samsung ICR18650 4.3 @ 4.17v - 2.0a (3cells)

Does that sound right? Thought there would be a bit more?
