Thrunite TN4A Review

My youtube review

Specification:
- Cool White / Neutral White
- LED: CREE XP-L V6 LED with a lifespan of 20+ years.
- Output mode/Runtime*: Strobe(1150 lumens/150 minutes), Turbo(1150 lumens /56 minutes), High(550 lumens / 150 minutes), Medium(139 lumens / 14 hrs), Low(15 lumens / 93 hrs), Firefly(0.5lumens/80 days).
- Peak Beam Intensity: 26640cd
- Max beam distance: 326m
-HI Cool White
-LED: CREE XP-L HI LED with a lifespan of 20+ years
-Output mode/Runtime*: Strobe (1050 lumens/150 minutes), Turbo(1050 lumens/56 minutes), High (520 lumens/150 minutes), Medium (120 lumens/14 hrs), Low (14lumens/93 hrs), Firefly(0.2lumens/80 days)
-Peak Beam Intensity: 52340cd
-Max beam distance: 457m

- Runs on: 4x AA(NIMH 2450MAH)
- Working Voltage: 2.75-8V
- Impact resistant: 2 meters.
- Waterproof to IPX-8 Standard (1.5meters)
- Weight: 218.6g without battery.
- Dimensions: 111.5mm in length, 45.5mm in diameter.
-Accessories: Holster x1

Performance:

as you would expect performance is MUCH better with rechargeable NIMH batteries.
I got a runtime of 47 minutes using NIMH Eneloops and 19 minutes using Alkaline batteries.

I got about 2 minutes warning from the red blinking switch on NIMH
and 3 minutes warning on Alkaline.

The light ramps down based on voltage. You can use the light on the lower modes for a long time even after turbo ramps down.

ceiling bounce tests for all 4 modes:
nimh – 13, 113, 524, 1119 Lux
Alkaline – 10, 114, 547, 973 lux

using my other ceiling bounce tests it falls between the TC10 and the TN12 in terms of brightness, so I do think it’s genuinely about 1000 lumen, give or take based on my rudimentary tests.

Construction:

No problems here. Thrunites have always been built like tanks! Threads are great, perfect reflector, great annodizing, the battery holder is fantastic! good springs.









Beam Shots:




My thoughts:
Thrunites are always built great and run great. it is so nice to have a 1000+ lumen flashlight that runs on AA batteries. 47 minutes is a pretty respectable runtime, and would be better with Eneloop Pros. It gets pretty hot, but not unmanageable. I particular like that the light ramps down, and that it does so with enough juice to run the light a while. On my test after the ramp down I was able to use the light on the low mode for well over 30 minutes. I couldn’t access turbo after it ramped down, and when it did, it only ran for a minute or two. The low voltage indicator appears pretty accurate and goes from solid red, to blinking, and then ramps down in power. The switch is blue during normal operation. The switch and threads are great and very very happy with this flashlight.

I bought the NW version, love the beam pattern. And I think I like the NW tint better than CW.

That looks like the HI from the hot spot. Was thinking I should have went with that, but bought an EA81 on sale. So now I have reach if need it and two lights. (yea, I know it’s not really a thrower. But it’s the brightest light Ihave ever owned. So far. Smile )

Nice review.
I just ordered a TN4A NW. Look forward to using it.
Although it is a 4-AA cell light, right? (This thread is in the multi AAA forum).

Yes it is AA. Can’t believe I missed that.

Mine TN4A NW just arrived. I will post pictures ASAP.
Everything is fine except 2 things:
- battery carrier was wrong assembled: springs against springs, but I fixed;
- diode is NW, but has noticeable greenish tint especially on low modes.
From all my Thrunite’s TC12 has best tint.
Anyway, I am quite happy with my flashlight. Now expecting Thorfire TK4A to compare with TN4A and TN4A HI.

Interesting, I had the same spring issue with the battery carrier: Review: Thrunite TN4A Hi NW (Pics, Beamshots, Runtime) Primary tabs.

I’d rather use my flashlight around the house than turn on the lights.
