Nitecore TM26 was factory upgraded to 3800 lumen!?!?

Edit!!!! I moved this conversation to the TM26 thread ... best to reply there: http://www.candlepowerforums.com/vb/showthread.php?353991-**NEW**-Nitecore-TM26/page42

I just got my second TM26 due to the smoking deal IS had ... I turned it on and was taken aback when the OLED said 3800 lumens.


Compared to my other TM26 that is only a month old or so, it still says 3500 lumens. The box my new TM26 came in also still says 3500 lumens.


Looking at the LEDs, you can see a difference (new on left, old on right). The '3800' LEDs have a silver PCB with 2 wires visible into the diode. The '3500 TM26' has a green PCB and 3 wires visible into the diode.



Anyway, I could have been living under a rock (I have been busy lately) but this seemed very noteworthy to me and worth sharing.

I hope a moderator can move this into the TM26 thread. No need for a standalone thread, and more people would see it there. It looks like they upgraded to XM-L2 LEDs! That's a great improvement...about 10% more efficient emitter, so an extra 300 lumens or so without making any changes to the drive levels. It is weird that they haven't advertised that...but maybe Nitecore is trying to sell off all the XM-L versions before they market the new version.

I just played with it some more and noticed the other modes are different.

Level 2 is 150 vs 95


Level 3 is 600 vs 540


Level 4 is 1850 vs 1700

hmmm so did they tweak the temperature thresholds as well?

could you please see how long it would run on Level5 before it steps down?

This may be exciting then, I'll break out my DSLR and get some better pictures.

Trying it right now

All of those line up well with the XM-L - XM-L2 upgrade except level 2. Strange.

Tail stand with no airflow, ambient temp of 68F was 3:44 with a step down at 62-63 degrees C.

it seems they didn't thank you for the test though!
