TrustFire TR-J12 Flashlight 5 * CREE XM-L T6 LED 5-Mode 4500

at least with these cheaper lights you dont feel so ripped when the next big bright light comes out and get stuck with a $200+ light.....

I recieved my 26650s today but they're not able to have in series any tip how to extend the + pole contact?

5-10mm diameter x 1mm height round magnet!

 

[HB021]

Ok thanks ill try find that
Edit: bought 3x 5x1mm magnets now

 

[ergotelis]

search in ebay, they sell them in 50x 100x numbers at a very low cost. But because i guess you can't wait, ask any local shop there!

 

[HB021]

Bought in local store, wanted them ASAP! 2,5euro each, got to love Swedish prices...

 

[Glenn7]

like to see how bright the light is now that the 26650 batteries are IMR Vs standard lithium.....

 

[HB021]

Here are lux test with 26650s instead of 18650s compared to 2,8A XM-L C8 and 11w 950lumen desk light:

Tail cap readings are with (4,23v) 3x2,1A and with 2cells 3,3A.

 

[Glenn7]

trying to understand your post and youtube vid - desk lamp was facing down and flashlight was facing up,so to me it doesn't seem like a fair test - would you not point the lamp at the roof too or point the light down like the lamp?
and you said "Tail cap readings are with (4,23v) 3x2,1A and with 2cells 3,3A." so your getting 2.1A with 3 batteries and 3.3A with 2?

Also from the lux reading in the video the TR-J12 is 4.5x brighter Than C8 (298lux divided by 66lux = 4.5x brighter) so assuming C8 @ 2.8A is roughly 600 lumens then by your lux meter tr12 is around 2700ish so maybe not much brighter than a Dry with only 3x XML.

I just compared the TrustFire TR-J12 on high with the Dry on high. The TrustFire is brighter. The TrustFire is somewhere between the high and the turbo of the dry.

 

[Glenn7]

Hmmm so trustfire will cost more be bigger,have a longer run time and run cooler but not be as bright as the DRY....tough one.

Can you share your exact readings, please?

Under construction :

Ceiling bounce, same location

Trustfire J12 with 2 cells - 225 lux (I put the extender at the bottom in this config to make it equal in height to the 3 cells)
Trustfire J12 with 3 cells - 215 lux (don't ask me why, tailcap measurements sometimes are not representative)
Cells are done with XTAR 2600 and TF Flames 2400 at about 4.2V full charge. I have other good stuff like Sanyo 2600, Panasonic 2900/3100 but don't feel the need to test, should be quite representative.

For ref : DRY CW in Turbo : 250 lux
DRY NW 5A3 in Turbo : 225 lux
DRY WW 7B in Turbo : initial 175 lux (I took out the power resistor inside, Chicago X may want to open his and check for it)
Fenix TK70 - 220 lux
Xtar S1 - 210 lux
Trustfire TR-3T6 - 130 lux
Uniquefire 3900 - 143 lux
Sky Ray SR3800 - 160 lux
SWM T40CS - 79 lux
SWM V60C - 79 lux also

Nice!!! Thanks for that reference list, this puts the TR-J12 ahead of the TK70 in constant power . Btw my lux readings with 3x18650 was 289max and 298max lux with 26650s.

Which 26650s did you use?

 

[ergotelis]

just got mine. First comments:

The bad ones, Silly PWM,silly disco modes, i don't like the button in the back, wish it was on the side. no UCL, can't find either one!
The good ones, excellent quality for the money and for a trustfire, too many battery configs available, good heatsink design,excellent square threads, generally nice design.
As for performance, see everything else and last one the trustfire:


OTF lumen, white empty room, 30sec measurements:

Itp xp-g S2 eos A3: 67 lumen
Fenix LD15: 96 lumen
Zebralight H51: 155 lumen
Olight i1 eos(cr123): 242 lumen
Nitecore ife2: 256 lumen
Jetbeam BC20(17670): 266 lumen
Zebralight SC60: 288 lumen
Armytek Predator: 343 lumen
Olight Baton S35: 382 lumen
Defier XT: 500 lumen
Defier X3: 600 lumen
Thrunite Catapult V2 XM-L: 740 lumen
Eagletac M3C4: 780 lumen
Fenix TK60: 790 lumen
Fenix TK35: 860 lumen
Trustfire 3*T6: 1470 lumen
Skyray 3*T6: 1610 lumen
Fenix TK70: 2290 lumen
Trustfire TR-J12: 2386 lumen


I posted the others for comparison, to show how other flashlights perform in the same test method . Trustfire tested on 3 AW 2900, 2,17amp draw.The flashlight starts@1sec@ 2430 lumen and falls by little.

 

[Glenn7]

2386 lumens ain't enough to make me pull the trigger - shame, I really thought they could do better with 5x XM-L - now if you could DD them but not with 2+ batteries.

2400lm, that's still a lot of light! I can lit up a big field with it, and leave it in for an hour or so. If you push the LEDs harder you could maybe get 4000lm OTF for 1min maybe

Thanks for the test ergotelis!

 

[warmurf]

This still looks like a great value light- can't wait for one of our modders to get their hands on it and offer an upgraded version!
Just a quick question- can you use 3 x IMR 26650s on these lights?


Really looking forward to the beam shot comparisons!!!

 

[ergotelis]

of course!
