ThruNite TN12(2014),1050Lm,1x18650 compact light,Review+Outdoor Beamshots

One more great compact,very bright flashlight is on the market. The new 2014 updated TN12 from ThruNite will give you one more flashlight to choose from when a new EDC light is needed. Compact size,Cree XM-L2 U2 LED,1050 lumen output and 5 well spaced brightness modes and no brightness step down!

Dimension: 143mm (Length), 25.4mm (Diameter), 82g weight (without batteries)

Uses 1x 18650 or 2xCR123A batteries

This is the first flashlight that has a pocket clip that I like and will use. It is not too stiff and will not tear my pants or backpack.
The clip has good shape and keeps the flashlight securely attached.

TN12 comes well packed in very nice,hard cardboard box.

There is a foam to keep the flashlight in place.

The accessories are under the foam. Lanyard,spare O-rings and very good sturdy holster.

This is my favorite type holster. It will protect the TN12 well. But I miss the velcro option for mounting.

There is only loop for mounting to a belt, e.g.

Unlikely for its price,ThruNite TN12 is precisely machined.No sharp edges.
Excellent anodizing.Beautiful knurling that reminds me on a Jetbeam and Klarus style precise,smooth knurling.
Black,more like gloss finish.

The cooling fins are required for good heat dissipation in such a powerful light. Side switch for mode selecting.
There is an anti-roll design,but actually without the pocket clip the light can be easily rolled.

TN12 tail-stands sufficiently stable.

The side switch has round shape. There is no similar feel around it when touching and I found it quite easy to use in the dark.Actually for me this switch is the easiest to find in the dark from all flashlights I tested so far.

Great care to detail.

The UI is simple and doesn't require time to get used to it.

Electronic(push button) switch for mode selecting. Short click to select brightness,press and hold to activate Strobe mode.
Instant(quick) memory for the last used mode(excluding Srobe).

I really like that this flashlight unlike most new flashlights has Ultra Low mode,which could be very useful sometimes.

All modes are current controlled.No sign of PWM.

The Strobe is the best I’ve ever seen! Great for self defense,but be careful because you might start seeing triple too. It does not change its frequency like the strobe in TN32/35.

This is a runtime graph showing the brightness curve through the time.
Battery Keeppower 3400.
U start 4,2V
U end 2,7V
Highest mode. 8cm cooling fan used.

As you can see,there was no step down to a lower output(to protect from overheating) after a few minutes as usual for most flashlights,big or small.
This gives you some more freedom and does not engage you to use 45% of the full brightness after just a few minutes.
You have the full power as long as the battery can hold it. The flashlight has thermal protection and will decrease the output if needed,but if you feel it too hot you can switch to a lower mode to extend the life of the LED and all electronic components.

From the graph we can see some great numbers. 94% brightness after 10 minutes. 80% after 30 minutes. 62% after 60minutes...
The flashlight has a low voltage warning feature and when the battery is depleted,the light will flash two times every 10 seconds.

The Turbo and High mode have only about 15% difference which sometimes is not visible.

ThruNite TN12(2014) is equipped with powerful and high efficient Cree XM-L2 U2 LED.
Aluminum smooth reflector,toughened ultra-clear glass lens with anti-reflective coating.

The light from the LED used in TN12 gives clean cool white beam,without greenish or bluish tint.My sample has a cool white LED.
A neutral white version is also available!
I like this light more than the light from the PD35.

The beam is flood,similar to the PD35's beam, which is normal for a small head flashlight.
The hotspot is a little bit smaller.

ThruNite TN12 has tighter hotspot than Fenix PD35,but according to my lumen measurements the PD35 still pulls out more lumens.

Beams aimed toward the base of the trees.

Beams aimed at the corona of the trees.

Fenix PD35 has a better grip due to its shape(especially with removed pocket clip) and type of knurling.

ThruNite TN12 is defenitely a great flashlight. It is very bright and with the Ultra Low mode and no unwanted brightness step down TN12 became my new 1x18650 compact/EDC favourite.
I like that the light from the LED has no greenish tint,and the beam is just what it should be for normal,EDC use.

What I think could be improved? The knurling is just amazing,but it doesn't give the same stable grip as the knurling used in the other ThruNite lights.
The difference between Turbo and High mode is not so visible,especially with not fully charged battery.

Having in mind the price and the advantages over its competitors,ThruNite TN12 is a great choice for powerful and compact 1X18650 light.

Thanks for reading!
