Review: Thrunite TH20 Headlamp - XP-L - 1xAA/14500

It ramps between low and high!

Haha well it could be my eyes also because mine are getting way bad. I really don’t see a green tint though in the picture or outside , but you may be able to detect it a lot better than me also.

I'm glad that your battery fit, but tell me, do these batteries look like they fit? I never said that no protected batteries fit; I said that two of the batteries I tried didn't fit and that there's no good reason for the tube not to be longer since there's plenty of spring in the tailcap. Don't put words in my mouth.

Efest @ 53.25mm --- not even close.

EVVA Protected UR14500P @ 52.51mm

My sample is NOT neutral white. I know what neutral white looks like, and this isn't it. Like I said, yours may be different, and it looks like yours and Robo819's copies may have a better LED than mine, but the one I got is a "garbage" tint, so when you buy this light you get to play the tint lottery.

I'm glad that someone is here to keep me honest; remember, this is a review, not a paid advertisement like most "reviews" are. Shill on and keep calm.

I think that “shill on” comment could be seen as being offensive to many reviewers here. Yes, we may received the product for free, but many reviewers including myself have enough honesty and integrity to point out the negatives (or at least use politically careful wording) during a review. Reviewing takes a lot of effort and long time, and even getting a free product is often barely worth the effort.

Incidentally, as you pointed to a product that you do sell, during your review of a product that you don’t sell, then your “shill on” comment is a bit of a case of pot calling the kettle black.

Have a nice day. :slight_smile:

So what we now know is there there is both a tint and length lottery. In other words unlike say Zebralight, Thrunite needs to work on their Production and QC departments adherence to spec (or the spec it self is too loose (see engineering and marketing)).

Let hope they take this fair and honest review and actually find more value in it then we consumers. Meaning if they actually take the time and make the effort to to correct the Tint and Length lottery then their product will be the better for it, and there is hopefully value in that to Thrunite.

Now we have a review that is just short of issuing corrective actions to Thrunite for free, that is a great deal for them. I say if they are smart they will see they received their monies worth.

Funny as I was thinking about a month or two ago how I rarely read about the “tint lottery” these days. In my recollection I used to read about the tint lottery so more often about, what 5 to 8 years ago?

From Low 1.6 lumens to High 230 lumens? What just happened to the Medium…?

What a horrible mode spacing…

Variable, almost infinite output between low and high.

Oh. My bad. I skipped reading the review when I saw the specs.

This really got my interest. I’m considering getting one.

Same here. Was surprised with this feature for this price. Check out a video on youtube, I think it’s pretty sweet.

The light has pretty much infinitely variable levels due to the ramping feature. Like I said, the user interface is pretty nice. If you get one with a good emitter you'll be happy with it for a AA light.

I got two neutral ones. Both Gross green. So I modded with Nichia 219B and diffusion film. Much better.

Just got mine in Neutral tint. My ~7 year old Zebralight H501 at 80 pure flood lumens was starting to show its age. Still a great light, but its old school XRE Q5 is a bit lacking.

Amazing how technology has advanced. TH20 is impressive, so much light from a single eneloop. I think I got lucky on the tint lotto. My only other light thats neutral (5000K) is an older Fenix LD25. My TH20 tint is very close to that at the 250L setting. Every Cree LED after the XRE I have found to have a pronounced tint shift when under driven. So I am willing to bet when my 14500 cells get here and I can drive the XPL harder, the TH20 will whiten up at the brighter settings.

Anyone have any impressions using Energizer 1.7V lithiums?

thanks!!

Someone point me to a tutorial and where to get parts to swap this pee green time led with a Nichia 219b!

I described how I swapped the led here:

A 219B, I guess a high CRI one of 4000K/4500K, can be found at Mountain Electronics, i.e. this one:

Or look around here:

I haven't checked this thread since the week I wrote the review after being criticized so heavily for noting that the emitter was green by the schills of the world. I feel at least a little bit vindicated to know that I am not the only one who received a tint-bin-reject emitter.

ThruNite did not complain about the review at all---in fact, they liked it and have asked me to do several since then, but I really don't have time to do them. I just needed to do at least one "sponsored" review to get it out of my system.

Anyhow, I would go with the 4000K 219C 90+ CRI at this point---higher flux bin, lower vF.

Will that be able to go to the max 540 lumens? I thought Nichias don’t have very high output?

Ya for the life of me how does a flashlight screw up the specifications for dimensions so that ALL batteries in the specified type fit.

I truly don’t see how a MFG screws up what must be light design 101.

And as a tint snob one hopes that MFGs will respond to someone other then accounting, but we can keep hoping.

BTW love my H’2 don’t know why the killed it. Put a Nichia in there and its a great reading light.

No. It won’t. I have nothing to measure it either but the nice tint is worth it for me. The nasty green tint wasn’t acceptable.
