ThruNite TN12, 1050 lumen,compact 1x18650 flashlight REVIEW+ Outdoor Beamshots

One more great compact,crazy 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 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.

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.

The tail switch is easy to access and use. Forward clicky with momentry ON option.

Great care to detail.

The UI is simple and doesn’t require time to get used to it.
5 brightness modes 1050lm(90min), 800lm(1.5hour), 280lm(5hours), 20lm(74 hours), 0.3lm(1585hours) + hidden Strobe.
Turning ON/OFF by the tail switch. Half press for momentary.
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.

The Strobe is the best I’ve ever seen! It just kicks! 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 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.
ThruNite TN12 (2014) is equipped with powerful and high efficient Cree XM-L2 U2 LED.

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

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.
I like this light more than the light from 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.

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!

TN12 provided by ThruNite for review.

Noticed that the led isn’t well centered, which should have been for that kind of money. Nice review!

great Review ! always like to see your great photos too of your review lights.
I noticed the side Switch cover… It looks identical to the one on a Nitecore EA4.

I always look forward to reading reviews; this was excellent as usual.

Thanks for all your efforts!

Great review as always!

I should be excited about this light, but I don't know why I'm not. Output is as high as can be expected out of an unmodded light, except for the TN32. It has a side clickie, nice low, nice mode spacing, a good set of modes including a turbo mode that gets that little extra bit of output even if it's inefficient, tailcap lockout, rear clickie with lockout and it can tail stand. The full price is a very reasonable $46 too. The lanyard hole doesn't let it tail stand perfectly with a lanyard though. Could that be the only reason I'm not excited? Or maybe it's Richard's 1600 lumen 18650 lights that have me spoiled. Not counting Richard's lights, I can't think of a better brand name unmodified 18650 flashlight that's pocketable, especially for the price.

Wow!… wonderful photos, FlashLion - and much thanks for the review.
I have the original TN-12 and I love everything about it but… levels 2 and 3 are a little too close IMO.
Seems they have fixed this in the new version. And the new side-switch… darn… I’m tempted :stuck_out_tongue:

Just one question: my TN-12 has a warm-ish tint which I like a lot. How does this new one compare?

Thanks guys. Glad you like the review. 8)

The tint usually depends on the light used for comparison. In use the light is normal cool white without greenish or bluish.Not neutral white,but it’s better than the light from my PD35.
The modes 2 and 3 are well spaced,but 4 and 5 are too close and sometimes the difference is hardly visible.I don’t know is this only on my sample.
Overall,I like this flashlight a lot. I measured the PD35 about 940 lumens. TN12 is brighter. My lumen measuring equipment is still in testing phase.

EDIT: I found that a version with neutral white LED is also available. :wink:

Here, how were you able to keep the light exactly in the same place while you clicked through the modes?

Your photos are impeccable, thanks again. :slight_smile:

Excellent review and outstanding photos! One question. I am curious on how hot the light got when keeping the light on the highest mode for that long? Was it too hot to touch or hold?

I tried it for about 10 minutes without cooling. The head gets pretty hot.There was no step down and I stopped testing. I took out the battery to see if it is too hot,but it was not. So the heat dissipation is good and heat goes to the cooling fins.
Just measured the current draw from the battery. On Turbo the current is a little over 3A. On High mode is about 2A. I will take some lux and lumen measurements later.

Very nice review again, thanks. But I'm glad it is not perfect for once:

"1050lm(90min), 800lm(1.5hour)"

:-)

Great pictures and review! I’m wondering does it step down from 800 lumens mode after a few minutes? Or it depends on the battery and thermal protection to lower the ourput? Thanks!

It was very hard because this flashlight has no good anti-roll design and I take pictures without special table or something like that. Patience is needed. :slight_smile:

I saw it,but copy/paste it from their website as it is,for more fun. :bigsmile:

I am also interested.Will test it and will make a graph.

Excellent review and outstanding photos!

Yes, I agree. On many lights I’ve noticed that the high/turbo modes are not much different.
It’s almost as if the 2nd highest level is more for power saving/heat management whilst putting out (visually at least) a similar brightness level.
At least that’s how it seems to me (kinda’ makes sense don’t it?).

Btw… If a neutral white version is available I’m IN :smiley: Woohoooo !

Great review, thank you! I love the side switch for mode changes, active thermal management and that the strobe is hidden. what a great looking light!

Thanks for the great review , FlashLion .

are the modes L>H or H>L?

thank you sir for the review, i was planning on to get the pd35 but just bought this one instead, killer deal and killer looking light.

For the price, I think thats it’s a definete winner :slight_smile:
