My youtube review:
Construction:
This light utilizes 2x body tubes so that you can use 1 or 2 18650 batteries. You can also use any combination of CR123, 16340 or 18350 batteries. It has a smooth reflector, large head with ample fins for heat sinking. There are springs on both ends of the tube so that you can utilize a wide range of battery lengths. Will use protected and unprotected batteries. Annodizing is good, threads are great, and the switch is excellent.
Performance:
Here is a comparison with a number of other single 18650 flashlights.
Here is a comparison of runtime and brightness using 1x and 2x 18650
Tailcap readings:
1x18650 - 0.0, 0.3, 0.47, 1.58
2x18650 - 0.0, 0.4, .50, 1.80
these were done with a cheap HF DMM and could be off by a bit. Bit you can see that readings are pretty similar
Runtimes:
1x18650 w/ ncr18650b 3400mah - 115 min
2x18650 w/ ncr18650b 3400mah - 127 min
1x18650 w/ 3000mah efest imr18650 - 102 min
surprisingly you don’t get a much longer runtime with 2x batteries, but you can see there is a massive difference in the regulation and how the light runs. You get max lumens for the entire duration using 2x batteries.
Ceiling Bounce test:
set up a ceiling bounce test to compare to the competition. This is done about 24” from a white wall and measured with a lux meter. I only did high mode only for this test. Of course, this is not very scientific… but I was as consistent as possible for the test.
TN15 - 1140 lux
Convoy C8 (with spring bypass ) - 1160 lux
Thrunite TC10 V2 - 952 lux
Olight M21 xl-2 - 941 Lux
Xintd c8 xp-g2 - 941 lux
BLF D80 (with Spring bypass) - 1308 Lux
Thrunite TN12 - 1450 Lux
Nitecore P12 - 1013 Lux
Defiant Super Thrower - 647 Lux
Thorfire VG10 - 910
Oligth S30 Baton - 1119 Lux
BLF 348 - 168 lux
Thrunite TN4a - 973 Lux
Thrunite TI3 - 124 Lux

User Interface:
This light uses a simple interface. Tail cap switch turns it on. Side switch changes modes. it has fast access to strobe with a long press when the light is on and a memory mode (minus strobe).
Conclusion:
This is literally my best light! Not only does it have one of the brightest hotspots, a good focused beam, and a super long run time, but it just
outclasses the rest. It can run full blast without overheating, in 1x18650 mode it may not be pocketable, but is very handy for coat pocket, glove box, or out applications like hunting, camping, hiking. The regulation in 2x18650 is fantastic. This light literally runs at 90% brightness for the entire duration of it’s 126 minute run. The bad news is that you don’t get any warning that this thing is about to switch off. The construction is good, this thing is very easy to mod, and is super tough… and is also rated for use on a weapon. mine came with a pressure pad, and Cutlery lover did a video of his on an AK47.
You have to remember that hotspot check with my lux meter shows this things is almost twice as bright as the convoy c8, and the runtime is almost 20 minutes longer. the fact that this light has so few of reviews, and more people aren’t raving about it is a complete and total mystery to me.
This is the light that turned me into a flashlight addict.
I may add some runtime tests in the future with 18350, 16340 and cr123 if I ever get some spare time. Given the long runtime of this flashlight it takes a whole evening to get through something like that.
