I hope the OP considers your good information.
I second the A01. I gave it to my 2 year old to play with in the lowest mode which is less than a lumen. He lost it. I found it 24 hours later still on.
I have a recommendation that does not meet your criteria, but I share it anyway. Thrunite Ti-3. I used this light with a lithium primary 3 weeks last September. We did not night hike. We did live away from most civilized contact for those 3 weeks. John Muir Trail, only supplies available on trail were at Red’s Meadow and Muir Trail ranch. I had mailed a spare AAA lithium cell to Muir Trail ranch, and did not use it. It was clipped to the brim of my visor and provided light where I needed it. I rarely used anything but firefly mode. BTW, I’m 56 years old and my eyes are not the greatest. You just don’t really need a lot of additional light in the back country. Advertised at 0.04 lumen, 12 lumen, and 120 lumen. mode order L-M-H. Actually not far off from your medium level of 20 lumens, likely could not notice the different betweeen 12 and 20, and run time at 12 lumens is 6.3 hrs. 115 hrs on firefly.
That said, if you really want something more “survival”, I would agree with those that suggested an AA battery instead. 3x the capacity with little weight penalty. No specific recommendation for an AA light though.
I’d choose an 18350 light! In my view these are giving absolutely best runtimes on a really smart kind of volume to handle at the moment. With an AAA-light I would not feel safe on a backpacker-tour.
A single AAA can go on for many hours as long as you’re frugal with output. But 18350 are indeed very good.
Actually while I would chose 18350 not a long time ago now I find myself with 18650 increasingly often. That’s because of Folomov and their powerbank offering; the extra feature makes the extra bulk worthwhile.
Hi,
The tank 007 e09 is pretty good, not sure if they make them anymore, but fasttech might still have stock. Not sure how long the medium mode lasts, but I found it a decent twisty keychain AAA light. Not sure how low the low is, maybe 10 or so…
Wow, thanks for all the great responses!
I think some facts are worth emphasizing.
1. We’re talking about an EDC, pocket flashlight. Not a primary backpacking flashlight which they’ll have in, well, backpack (likely a headlamp).
2. Any backpacker going on such trip ends up at cities, towns & villages most of the time. Most hikes are day hikes; most overnights are in huts, designated campsites etc. In other words, it’s not very big on being out in the woods at dark.
3. We’re talking about young women, medium built I’d say, 1.60m tall. Not gear junkies or EDC freaks 
So with this in mind:
AA vs AAA
AA will certainly make it easier to satisfy my requirements, but I’m afraid the added girth girth/weight will compromise the “carry-ability”.
It’s a small coin-pouch with: knife, flashlight, botane lighter (+ waterproof cover), whistle, and 2 plastic tubes for pain killers, water purification etc. I wish they carry it all the time, whether they’re going to party in city or on a hike in the woods. The comfort and discreetness factor is highly important.
The knife (Vic Walker- blade, saw, combo tool) is the biggest item at 84mm length and 14mm thick. I’m trying to keep everything else smaller.
A possible alternative would be to have an extra AAA battery in the pouch (wrapped) - adds just 12gr or so.
20 lumen vs 12/15
I considered both Thrunite Ti3 and Nitefox K3.
I compared my own lights at 3 different (advertised) output levels: 9 / 20 / 25 lumen. Based on that I think 12 to 20 lumen difference IS noticeable. I think hiking an unknown trail with 15 lumen is doable, but it would feel easier with 25 lumen. If you find yourself outside on an unplanned night-hike (lost your way/got hurt/had to turn around/whatever) you want this little bit of extra because:
- good chances you’re not at your best;
- you’re not prepared for a night outside so it’s important to move fast to somewhere safe.
I’ve researched the topic on this and other forums, and it seems that most people consider 25-30 lumen as the good-enough output for a night hike.
Regarding that Astrolux A01, I couldn’t find any reliable output/runtime information. Anyone has got the numbers for the currently available offering (I understand they changed the driver not so long ago)?
Thanks again for your thoughts and suggestions!

Bamba,
Is the criteria of having available batteries important? Otherwise, there could be another (eventually) good solution (in terms of output/runtime) that is the Nitecore Tip 2018. It is USB rechargeable (through Powerbank or electricity), has a good ouput and despite being bigger that an AAA light, it is quite “concealable” in a purse or pocket!
I use mine on the neck, sometimes , with 2mm paracord adustable lanyard. Maybe it could be an option too!
EDIT: It has memory, so it will turn On in the last used mode, though :zipper_mouth_face:
Left to right, AO1, Sak with lite, watch, lighter.
AFAIK, Astrolux A01 and Manker E01 are the same light. Manker is advertised at 7 lumens on medium mode, so it likely does not meet your criteria. My data is from a couple years ago, so if there is a new driver then maybe the light is still worth considering.
Just found a post from January 2016 regarding this light.
The Tip looks very nice. I have a couple of Tubes that stopped working after a few months. On one it was a disconnected battery wire (which I managaed to solder back in place); the other I don’t know. But I read the Tip is tougher and more reliable overall.
Anyway I like the built in rechargable batt., no issue for me. I’m concerned about the IP rating, the other lights mentioned so far could go for a swim, not the TIP.
Also on the pricey side.
But I think I’ll get one of those for my wife.
That’s a nice EDC! :+1:
Thanks, yeah I saw this post and others, there was one mention of 21 lumen but that was on another thread a few years ago.
I think I’ll pull the trigger on a couple of K18 in the end…
And encourage the girls to keep an extra AAA in that EDC pouch.
If these lights are just for a small survival kit, I would recommend a fenix EO-1 with a lithium battery. I know it doesn’t really meet your criteria but they really are bomb proof and have nice runtime. I put them in the small survival kits I made with a extra lithium battery and they take very little room. For a primary or even a back up light I would definitely go with something bigger at least AA size.
How about a jetbeam jet u
hard to compare lights if you’re looking at specs and runtimes given by manufacturers . Most of whom lie their butts off
I was going to ask if you were counting ounces but it looks like you are counting grams. Yikes. I am all for minimal but dang. My brother cuts every strap to absolute minimum length, his tent is paracord with a plastic sheet, has modern lightweight clothing, etc… His emergency kits are like yours, but maybe a bit more. May I suggest someone carrying a venom extractor for bug bites, wasp stings, or snake bites… If the light you are looking for is truly emergency use only, a AAA seems okay to me, but AA makes more sense in almost all scenarios.
I also like the E01 for small survival kits.
There’s a catch here: this is not a survival kit.
It’s an EDC kit, that’s supposed to have enough usability for common hiking/backpacking emergencies.
13 lumen is too much for indoor use when you don’t want to disturb your fellow; on the other hand it may be too little for a forced night hike.
That’s true. I happen to EDC the K18 myself so I know what to expect from it.
Given that ALL runtimes are inflated, we can still compare…
Regarding that Jet-mu, this is one of the few cases where I saw a review claiming much longer runtime on mid than advertised. But I didn’t see any other reports supporting that.
Have you read the original post? or my first reply to responses?
1. This is not MY survival kit.
2. It’s not a survival kit in essence. It’s a small EDC kit that’s supposed to have enough to aid in survival/emergency situations, related to hiking and backpacking.
It’s not replacing a bigger flashlight, just providing a handy source of light that may be good enough if push come to shove and that “primary” flashlight is somewhere else (common scenario for global trotters that carry a big backpack and a small day pack).
Pocket EDC has a lot with counting grams, yes!
For instance, a lot of “knife people” like the Victorinox Farmer (86 grams) for EDC, but consider it too bulky & heavy for pocket carry.
For this purpose the the Cadet (46 grams) is much more popular, even though it has limited usability in comparison.
“The best knife flashlight is the one you have when you need it.”
Lumintop Tool aaa version . (Massdrop aaa flashlight low-med-High)
Jetbeam mu aaa flashlight.
Just my 2 cents.
