If you're like me who does a LOT of research before buying anything, let me save you the trouble. This flashlight is worth it.

This was my second E12 after I lost my first one in the mountains. The flashlight is fantastic and I've used it on average about three time a week for a few years. I just wanted a good flashlight that uses a normal, easy to find AA battery. The three light modes on this are perfect. The low light is great when you need to walk to the kitchen in the middle of a night for a glass of water or looking around the inside of your car or desk. I medium is great for lighting the trail ahead of you or looking for something in your campsite. The max level really lights up the woods in front of you about 50ft. Know what you're buying. This is not a substitute for the sun or a 800 lumen Surefire or something like that nor does it have any SOS signal. This is a fantastic EDC that's works as an excellent all rounder. And when the battery starts to die, it's doesn't just go out on you all of a sudden. In my experience, you'll first start to lose the high level output. Then about two to three weeks later, you'll lose the medium. Then about another 2-3 weeks or longer the low will slowly start to lose the low setting. It's a great warning system and it's plenty of time for you to switch out a new AA. For me, I use the low and medium settings for 95% of my tasks, so I replace the battery once I lose the medium setting, which is around 2-3 months for me, depending on use. And I use a regular Duracell AA, nothing special. My advise on this flashlight: just buy it and try it out. If you don't like it, just return it, but the odds of that happening are very slim. If you want to get into the world of EDC flashlights, I cannot think of a better one to start with. It's an honest EDC flashlight that's durable (I've dropped it a lot and sometimes into water) and gets the job done. If you're budget conscious like me, and does a LOT of research on every company under the sun to get the best value, the let me save you the trouble. Just start with this flashlight.

this is for the ThruNite TN12 2016 XP-L Neutral White EDC LED Flashlight

Great flashlight. Sifting through all the tactical crap you find when looking for a modern, good quality flashlight can be tiring. Not everyone who wants a lithium flashlight also wants to mount it on a knife attached to a gun that mounts to a motorcycle.

Buy this flashlight because it is old enough that all the kinks have been worked out in the design, casts 8x more light than your dad's maglight, and fits in your pocket without looking like your going to conduct a swat raid later that evening.

I got two 3400mAh orbtronic 18650 batteries as well as the thrunite U1 charger that comes with a battery. My dad loved this flashlight so much he asked me to order him the same three items so he could have it for himself.

I have bought many flashlights in my life.  This may be the best one yet.  It is a compact size with a really bright light.  It even comes with batteries. I read some postings that said they could not figure out how to install them.  It is quite easy.  Just unscrew the black ring where the lights are, slide out the battery holder inside (be sure to keep it facing the same direction it comes out), put one battery in each of the three slots with the positive end as indicated, or it won't work til you reverse the direction.  Make sure the batteries are in place completely, or it won't work...ie if slightly off the contact point...no good.  Slide the holder back into the body of the flashlight, screw back on the part with the lights.  Yay!  a great flashlight.
We hooked the carabiner onto the wire shelf where we keep flashlights in our pantry, so it won't fall, and if it does, it is not going far.
I don't care if it floats, as that is not in my plans, but it is a nice extra.  I have never written a flashlight review before, because til now, others were were ok, or not so good, but this one deserves kudos.  Admittedly, we have not had it really long, but so far, it is beyond good.

This flashlight is amazing. It takes a little bit of time getting used to the half tap feature to get to strobe and half brightness, but once you do it's pretty intuitive. I love the rubber protruding switch, it's just as strong as the rest of the light. The brightness lights up a whole backyard when needed, and inside would be blinding to an intruder. The battery life is what surprised me the most, I got three months pretty heavy use out of these batteries, before I noticed them getting dimmer. Then another month and a half before they completely died. This thing has been in flood conditions, in mud, stepped on, dropped more times than I can count, and I have zero problems with this flashlight and it still operates as good as day one (albeit, it's a little dirtier than it was on day one). I would recommend this flashlight (and I have) to anybody who wants a great EDC flashlight.

This ia a seriously bright flashlight!  I don't know if it's 1000 lumens or not but it's the brightest light I've used by far.  At full power it's blinding inside the house.  There is no comparison whatsoever to the much less powerful (and lower output rated) lights I've used in the past (Fenix, Brite-Strike & Surefire lights in the 100 - 200 lumen range).

The light has a fairly wide beam.  I think it would be better if the beam were focused more narrowly and had a bit longer throw, but it works very well as is.

Flashlight build quality and materials appear to be very good, at least as good as the Fenix lights I'm more familiar with.  Comes with spare O-rings, spare tail-cap rubber switch cover and a lanyard.

One nice feature is the ability to check the battery voltage level by holding the mode switch in while pressing the tail cap switch.  A blue LED blinks to show the battery voltage (for example, 3 blinks, pause and 7 blinks means 3.7 volts).

The rechargeable battery is another nice feature.  In the long run it will save money over buying disposable batteries.

The only downside is the included UM-10 charger did not work.  I tried the different switch settings, different USB cables, etc. and it just would not charge the included Nitecore battery.  I borrowed a friend's charger for my first charge and then decided to go ahead and buy the Nitecore D2 charger.  This is a nice charger that charges a lot of different sizes and types of batteries.  I went with the D2 over the D4 to keep the size down but if I was going to do it over again I think I'd buy the D4.

At this point this flashlight seems like a no-brainer if you need an extremely bright but pocketable (OK, larger pockets) flashlight that can run on rechargeable batteries.

This was something I really had to think about before buying as spending over $100 on a flashlight sounds well, quite absurd.  But I did it and found out I would never look back or regret it.  Amazing light quality, amazing craftsmanship, I can't seem to find anything that would make me question the design or ways they may have "gone cheap".  I am exceptionally happy and would love another but spending another $100 on a flashlight I already own that sounds REALLY absurd.  But who knows, I just may do it...great light don't second guess yourself and remember, no more batteries to buy!!!!!

I didn't have a lot to spend so I was prepared to "get what you pay for." I walk my dog at night and I have so many flashlights, spent so much money. They all claim to have so many LEDs you can see a mile out. Not really but it seems like it.
This flashlight is amazing. You really can see whats going on. I've never had such a bright, focused flashlight.
The stun gun works! Here's how I use it. If I see someone walking towards us I just hit the stun button for 1 second, it makes a big spark and a loud threatening  sound. Then my dog goes nuts because of the noise. That is really all I have to do. I'm letting them know I have a stun gun, know how to use it and a dog that's aggressive.
It's small, easy to hold, I love it. It gives me the security I need when I walk at night
Thanks for making it affordable.

Like most guys I have a lot of flashlights most of them very cheap, I decided to get a high quality one for my bug out bag. I looked at almost every flashlight on Amazon and read a ton of reviews, I saw hundreds if not thousands of reviews on SureFire flashlights, guys just going on and on about how great they were. I was skeptical and found it ridiculous paying $60-$100 for a flashlight but I finally pull the trigger and bought the G2X Pro Duel Output. Now I'm on board, this thing is awesome, its built like a tank. You can tell when you have it in your hand that it is built very well and they paid attention to detail. I like it so much I decided to make it my every day carry light and I bought a StreamLight as a backup light to carry in my bug out bag (the StreamLight takes AA and I have a solar battery charger). I also bought a 12 pack of cr123 SureFire batteries to put in my BOB for the G2X, on low setting the battery life is good so this will last a long time. While the StreamLight is a very good light and a little cheaper, I think it was well worth the money for the SureFire, going from high, low, strobe is much easier on the SureFire, it's brighter, better battery life, and overal feels much more durable. If a A-Bomb landed right on the SureFire I feel like it might survive, that's how tough it feels. It was well worth the money and I would highly recommend it to anyone who wants a well made high quality flashlight.

A well constructed flashlight that puts out a lot of light for the price. This flashlight is as bright as those costing a whole light more, but the key lies in getting a good strong battery. I'm using UltraFire 18650  5000mah and they work great and are long lasting. Batteries with less power obviously won't last as long and aren't as bright.

It's a Maglite.  You can go wrong.  The light is powerful and the distance it reaches is impressive. The batteries last really long.  I gave four starts because for that price you will find more potent (more lumens) flashlight in the markets, not necessary the same quality as a Maglite.  Any ways you won't be disappointed.  A 274 lumens Maglite is at 30 feet or farther more powerful than a 400 or 500 lumens of most brands (not all). I recommend it.

I like not having to live with a fixed focus long narrow beam. This flashlight can be focused to light up as large an area as needed. The small included flashlight lives on only 1 AA battery and will also focus excellently, and, by itself, will fulfill a far superior performance to an ordinary flashlight. The lit areas of both flashlights are ample and huge! The set arrived very neatly boxed, and would make an excellent gift for a very good price. Stay with high quality 18650 batteries like the included ones. Don't  get scammed by the cheaper imitations!

I literally had to talk myself into paying this much money for a flashlight.  I thought for three weeks about spending the money on something I couldn't see up front.  I finally decided to do it.  I am so impressed.  This flashlight is extremely bright and is built well to boot!  It has already been dropped, banged, and stepped on without even one little battle scar.

The only possible negative thing I can say about this flashlight is that if you are looking for an extremely long distance light this is not for you (nor is any LED flashlight).  If you are looking for a great little light to have around the house or use for sporting/hunting purposes it is great!

I am so impressed with this flashlight I am thinking of buying a couple more!

Excellent Flashlight! Even better than the hundred dollar ones I keep going through.

Years ago, I bought a Surefire and it put a blinding 65 lumens. Then I upgraded it to 100 lumens and it was a great light. Batteries were about a buck apiece and all was well with the world. Now it's 320 lumens and only $63. It's still a rugged little light, very reliable and, like the older G-models, comes with two CR123 batteries that power the light for 2.75 hours at full power for 2.75 hours and 15 hours at low power.

The downside of the light is that for the money you can get flashlights with longer runtimes, more modes, at least as durable and rugged and for about the same amount of money. Try 1,000+ lumens in a body of HA-III aircraft aluminum, multiple modes and runtimes up to more than a week for less money. For example, the Klarus ST15 CREE XP-L HI V3 LED 1100 Lumens Watereproof Flashlight for $50. It has three modes, takes 18650 rechargeable batteries as well as the CR123 batteries that the Surefire does. Whatever Surefire light you're looking for, rest assured there are many better, equally reliable and better lights by Klarus, Fenix or Nitecore. Surefire is reliable, but overpriced and behind the times. If you're a cop and want a small, medium bright light that won't blind people in cars, it's a safe bet, but in my view there are better lights at a cheaper price. Many times a 1000+ lumens will be too bright for routine stops, but there will be times when you'll need the extra light when searching ground next to highways and in the woods, and the Surefire's a little anemic. Fenix lights and Nitecore are both exceptionally reliable lights. Take a look, too, at the Klarus AR10. Carrying a light that takes rechargeable 18650 batteries is nice because runtimes are better and spares can carried easier than new CR123 batteries. One of my favorite lights is the Nitecore SRT-7. These lights have been used by divers who have used them as dive lights at 70 feet under water. The SRT-7 also has red, blue and green LED lights that can be used alone or in combination (such as alternating flashes of red and blue emergency lights). They've also been torture tested and have passed with flying colors!

The E12 has proven to be an outstanding multi-purpose flashlight. I know that it's popular with the EDC (everyday carry) crowd, but even if you aren't into that you will be pleased with it. I ended up buying several: one for the glovebox of my car, one for my toolbox, and another for around-the-house tasks.

There is certainly no shortage of rugged LED flashlights these days, but the E12 has been a winner in my book for a few reasons. First, it uses a single AA battery. A lot of these ultra-bright ones that are best-sellers on Amazon need a lithium battery that costs $10 or more. No way am I throwing that kind of money away on batteries for a flashlight that only gets occasional use. Another reason I'm loving the E12 is because of the size. It's small enough to hold in the palm of your hand without feeling like you'll misplace it or drop it, yet can also be maneuvered into tight spaces like the engine bay of a car or behind furniture. The third reason I bought a few of these is that they're able to take a lot of punishment. The one in my toolbox has been dropped onto concrete repeatedly, smacked against objects in my car's engine bay, and has suffered some accidental blows from my wrenches and hammer -- and it just keeps on ticking.

The E12 has three brightness modes but I rarely find myself using anything other than the dimmest setting. If anything, the highest setting is only for use in very dark environments such as a forest in the dead of night. I tried using the brightest setting while working on my car and found it to be overpowering: it simply reflected off everything and made me squint.

For the price paid I think it's really hard to beat this. It fits just about anywhere and uses cheap/readily available batteries. It'll take abuse without any issues and I won't cry if it does break (since it was only about $20). I can't bring myself to spend $100 on some of these fancier ones when you can get 95% of the performance and quality for so much less.

I have to confess I bought this flashlight on impulse thanks for suggesting it Amazon. My wife will tell you I've I have never seen a flashlight I didn't want. She's only partly right but it was true this time.

This is a quality product and is very bright for it's size and intended use but you cannot expect it to be a 'real' flashlight. It is amazingly small and made no noticeable difference to the bulk on my keyring.

If you decide to buy the Nano you may want to buy a small supply of batteries at the same time. Not because the batteries don't last but because when they finally do die you might have difficulty finding replacements.

As a low-cost backup to my backup this little flashlight really shines.

Ok, I will admit it here on Amazon: I have a flashlight fetish.  Whew, there, done.  I feel so much better now.

With that full disclosure behind us, this $16 flashlight is wildly bright.  It is brighter than every flashlight I own, and I have many.  My brightest halogen Streamlight cannot touch this especially when you consider the size differences.

I agree most are thinking it is another cheap import product that is often just rebranded for the PepBoys check stand or Lowes, regardless, the quality is reliable enough. I am tough on it and it is holding up great.  It was not DOA, no complaints about the switch on the base; just a very small palm sized light that has huge light.

When I first got it, I forgot about the 3.7v battery issue.  It is an odd size for the average handheld light.  I picked up a few Duracell CR17345 3v batteries at my local Kmart (yeah still in business).  Together these were over the limits of the light's 3.7v rating but no one had a single 3.7v lithium battery so I tried it.  Although they did work and lit up my entire living room with a clear white HID quality, after using them I noticed the light was getting hot (Danger, Danger, High Voltage!) and ended up buying the suggested rechargeable Tenergy 18650's.  Those arrived and I was worried the doubled 3v batteries were going to be way brighter than (1) 18650 3.7v.  Not the case. Perfect.

So as a guy that really likes collecting different flashlights, you really need to try this.  It will not disappoint.  The only exposure you have may be the quality could be hit or miss based on other reviews.  Mine was perfect.  I am buy two more for my kids' to have in their cars. Btw, the Tenergy rechargeable is exceptional.  I left the light on for (3) hours and I could barely see any dimming.  I had to turn it off because it does get pretty freaking warm.  Great hand warmer if get stranded on winter evening and have to hoof it.  Do be sure to get the battery with the protective PCB.  There are many out there, look for the over limit PCB.  Will save the light.  Batteries are pricey in relation to the light but well worth it.  I use my modestly and still on the first full charge.  I bought (3) batteries thinking it would suck them up fast; not the case.

Enjoy!!
