I have a TN11S review
The TN11S is about the same lumens on 18650 and 2x16340 but is bigger, thus it has more throw. Also the Crelant has ramping while the other has set modes. The Crelant geys much lower.
Non-hidden strobe on TN11S is a turn-off. Actually looking at the TN11 now. Sort of like it’s twist-to-turbo UI better.
First hello to all members and flashlight fans!
I have this flashlight from aprx 3 years (XML U2), as you know is not so bright with 1x18650 and no regulation, I had few unsatisfactory attempts with 2x16340 (poor runtime) and I ended with Xtar IMR 18350 850 mAh. Matching is OK (I think no other 18350 can fit because dimensions)
Very good quality, true capacity and with them the flashlight is insane bright, flat regulation, no steps (!) full power easily for 25 min (I don’t know the current at the led) , test made 5 minutes max , 2-3 minutes cool down, 5 min and again 2-3 min cool down, because are no steps the flashlight can go exaggerated hot after 6-7 minutes on max!
On max output compared to my Eagletac T200C2 and I don’t see any difference on the brightness, of course aprx 100 lumens between ~750-850 is hard to see, there are some differences on hotspot (little more focused on Eagletac) but at general brightness to little difference to be observed on naked eye.
This flashlight I put it on “storage” more than a year because I was not satisfied how goes on 1x18650, but now in 2x18350 configuration became again one of my favorite for close actions 
(because it is without discussion a flood light) .
PS: sorry for my bad English
