XM-L2 recently came out. The bins are roughly equivalent to 2 bins higher than XM-L. XM-L2 U2 ~= XM-L U4.
I’ve place an order of TN31(XM-L2 U2 1C version) baby after I receive this New Product emails.
I thought I ’ve been their dishes, 
hopely reach out my expectations.
$165 + free shipping
Hello Handsome, welcome to BLF.
Please edit the swearing from your post (even though I find it slightly amusing).
Handsome,
We don’t talk like that on this site. Please fix your post. That’s uncalled for.
Pls fix your post!
Sorry guys.
i wonder if they still using the same driver but with new LEDs?
technically we can change the driver to 4 Amp with these new LEDs 
Onestopthrowshop.com says the original TN31 had 130Kcd. The new one has 90000cd so how does that compare because the math does not seem to add open when Thrunite says the original has 75000cd?
At 165USD shipped it was too tempting to resist. The TN-31 U2 I got is just one month old, and still very easy to sell without loosing much money in the process (it was in the 139USD deal with the free T10), so....
Ordered! 
I read on a german forum that the original driver can be modified to go to 4+amps by changing the resistor values.
woo hoo… i wonder how much lumens does it add? 
hm… can i change the resistor value on the old TN31 too?
I was refering to the old TN31
Here is the driver mod tread on that german forum using google translate
Alex, thanks for that link!
My Supbeam K40 has 1ohm and .82ohm resistors in parallel (which means 0.45ohm in total), compared to my TN31 which has two 0.82ohm resistors in parallel (for a total of 0.41ohm).
So if I’m not wrong, to find out the current going into the emitter (at Level 6) from changing these resistors, it’s 1.435 divide by total ohms from those resistors.
Stock TN31: 1.435/.41 = 3.5A
Stock K40: 1.435/.45 = 3.2A
TN31 with three .82ohm resistors in parallel: 1.435/.28ohm = 5.1A (matches the readings from the taschenlampen forum thread!)
Seems about right to me! Now I’m going to hunt for some resistors :bigsmile:
thanks… 
I gave in at work and ordered the new T31.This is the most I’ve spent on a light so far…hope I didn’t make a mistake.So much for BUDGET light forums!I love you guys, but you are really starting to cost me!-Rick
My TN30 sent from China on Friday just arrived this morning to the UK, impressive!
Will try and get some comparison shots tonight with my old TN30.
Ordered 13/01, delivered (in Italy) 15/01. Unbelievably fast!
Now I have both TN31 XM-L and XM-L2 in my hands.
Inside the house, just aiming at a white wall, the difference looks minimal. But at this lumen level, the eye is not a faithfull judge, as I really feel my eyes "closing the shutter" to be able to look at those bright spots.
One thing I noticed is the tint. The XM-L2 should be a C1 cold white, but from direct comparison it's a little more neutral than previous version. Almost pure white.
I'll have to test outside.
Between the two versions there's a difference in the lens, the anti-reflective coating is completely different. On the XM-L version it has a definite blue-purple pitch, on the XM-L2 it's not blue at all! At first, I thought that maybe I got a lens without coating, so made a comparison with a cheap lense that has no coating at all. Well, the lens has an anti-reflective coating, just it's not blue. It's sort of neutral. Does not change the colour of the reflected images, just cuts the reflection to a much lower level.
I'm just waiting for the perfect conditions to get out and take a few beamshots comparing my old & new TN30, like you said indoors it's hard to spot the difference.
Here it's raining like there's no tomorrow... no outdoor testing today...
Cm2010 on yours did you notice any difference in anti-reflective lens coating?
