Warning: Do not mix batteries of different brands, sizes, capacities or types. Doing so may cause damage to the flashlight or to the batteries being used.

Battery Replacement

Unscrew the light tail and insert the battery with the anode side (+) towards the light head, then screw the light tail back on.

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.

Intelligent Protection

The light will accumulate a lot of heat when used on High output level for extended periods. When the light reaches a temperature of 58°C or above, the output will automatically step down by about 1% every 1 second until to Med to reduce temperature. When the temperature is reduced, the output will gradually increase by about 1% every 5 seconds until to High. The original output of every mode is restored each time the light is switched.

Note: *The above specification is from the result produced by Fenix through its laboratory testing. Actual output may vary slightly according to the working environments.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:

A: The battery needs replacing.
Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s   specifications).

B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.

    Excellant EDC, Fenix delivers.

  2. JOHN M. (verified owner)

    It came highly recommended, and it is just as expected.

  3. Debra Farrell Jenne (verified owner)

    My husband loves his new flashlight!

  4. Walter (verified owner)

    The absolute most wonderful lighting device you could ask for – bar none.

  5. Bradley (verified owner)

    This flashlight is a nice hand fitting size. The tail cap button is easy to use as is changing between functions. I like being able to use rechargeable NiMh batteries, bit It would be nice if it were capable of using rechargeable lithium/LiFePO4 batteries also. I highly recommend this flashlight for EDC or around the house.

  6. Ernest Hercher

    This is my first Fenix purchase and will be my last. The e20 l bought broke within one week. The tail switch went haywire and will not cycle thru the brightness levels. I will go back to Browning and Surefire.

  7. Marcus (verified owner)

    An excellent 2 AA flashlight, among my favorite. Very compact and light for a 2AA light. 4 modes are spaced nicely. Has a nice broad hotspot with good amount of spill, it is more on flood side with decent throw. It starts on low and would be perfectly fine IF it had mode memory, but it always starts on low, I myself can get passed it but do wish it had memory and bet a dingy of a star due to this. Otherwise a great quality light and looks good to boot.

  8. Edgar D. (verified owner)

    Great product and quality made.

  9. Lawrence (verified owner)

    Best EDC AA light ever.
    Puts light EVERYWHERE! Light goes almost 180 degrees. Please build an 18650 powered version of this light.

  10. Scott (verified owner)

    Very excellent light with the AA nimh, or alkaline option. No frills, tail switch only, perfectly intuitive, plenty bright at 350 lumens on Turbo. Highly recommended.


    I had an old E21 that I recently sent in to Fenix for a warranty repair. It was what I thought would be a minor tail cap repair, but Fenix went above and beyond by sending me back a brand new and highly upgraded E20 V2 light. Way to go with standing behind your product Fenix, and for sending out my new E20 V2 so fast that I was without a flashlight for really only a few days. This E20 V2 is a great light! I am shocked at how bright it is on High mode. Thanks for the great customer service!

  12. Dan P. (verified owner)

    Very Happy with this lite, would highly recommend. I’ll be looking for other products as quality is also spot on.

  13. Andrew F. (verified owner)

    Just received my E20 V2.0 and am very pleased with it (and the shipping was lightning fast, even in pandemic times!). The small size is a delight and it feels great in hand or clipped in the pocket. The beam is very nice with a good combination of throw and spill. The hotspot makes a soft transition to the spill, which I like, but still has good reach. The spill is broad and really lights up the yard. I’m not tint obsessed but this one suits me fine. I’d call it neutral and very pleasing to the eye.

    The build quality is just excellent. The threads make for easy removal of the tail cap and came with a light application of lube. The tail cap button is a real joy. It has a nice crisp feel when pressed all the way and the momentary function only requires a very light touch which allows for smooth and quick changes between levels.

    As to the output levels, I’d prefer the low (30 lumens) to be a little higher. As is, it doesn’t seem quite bright enough for lighting the immediate path. But medium at 150 lumens really lights up the entire near-medium distance, and the promised runtime on it of 5 1/2 hrs. is terrific. High is very impressive, but for my needs medium will normally suffice.

    Keep in mind there’s no memory and the light (after a few seconds off) reverts to the lowest (“Eco”) level. As I mentioned, the tail cap button is a pleasure to use, so ramping up to whatever level I want is not a problem. Also, I’m more used to lights that either have a twisty head or a side switch, so the tailcap only operation here means more use of a hammer grip, which for me will take a little getting used to.

    In sum, this is a very quality light, with impressive performance in a small and sleek body, and offers a lot of bang-for-the-buck. Fenix has a real winner here.

    Ordered 3 weeks ago. Said shipped on 6/25. Still not received as of 7/16. I will change this review once I actually receive the item.
    UPDATE: received items on 7/20 and could not be happier. It works great, is easy to use and is super bright.

    • Dianne

      Hi Peter – yes, from the tracking it looks like the package was sitting at the post office from the warehouse for almost 3 weeks before they scanned it in and got it on it’s way to you. Glad it finally made it there and that you love it.

    Best double A light I have found

  16. Jesse L. (verified owner)

    Haven’t had it for long but is great so far. Light small and bright. Interested to see how it holds up and how the company responds to possible mechanical or functional issues that may arise.

  17. Chris S. (verified owner)

    Good size just not quite as bright as hoped

  18. Kelly G. (verified owner)

    Not very happy with this light. I didn’t read that it had four modes and that I would have to click through them to get to the brightest setting. I like the size and the Fenix reliability, but I doubt I will use it much with all the clicking.

    • Dianne

      Hi Kelly, please note we do state on the product page that it always starts on low – ” It has a maximum output of 350 lumens and the tail switch operates all functions including on/off and four brightness levels, always starting on low.”

  19. Ronald Lopez (verified owner)

    Really pleased with this purchase. Use it when backpacking and as an every day carry.

  20. Robert Y. (verified owner)

    Great light, same feel and durability I’d expect. The throw is a nice medium, where it’s broad but has enough to make walking in the woods at night easy.

  21. kevin w. (verified owner)

    Love it Super bright and easy to carry! Would definitely buy another one!

  22. Anonymous (verified owner)

    Love it. I wish it was just 1 AA.

  23. Joshua (verified owner)

    Great little light with excellent fit & finish. Surprised how compact it is for a 2AA format. Threads are top notch as is the anodizing. Tint is acceptable but I don’t U sweat and why fenix chose the low CRI version of the sst-20, they were so close to knocking this one right out of the park. Note that mode order is always low-medium-high without memory. This is excellent for most general use and especially camping where extended runtime is useful. The low could be lower without loss of usefulness.

    Overall excellent light fro fenix. Why low cri when you are using the sst20 though??

  24. Tyler (verified owner)

    Excellent light with the right amount of lumens. I carry and use it everyday.

  25. John D. (verified owner)

    Love this light! Very well made and a great value. Plan on buying another one.

  26. Anonymous (verified owner)

    I hate to give this light a poor review but I’ll be honest. This is my 3rd Fenix. I’ve owned a LD22 [a great, functional AA torch] and then bought a PD35 Gen 1 for my brother as a police duty light [again, a great tool]. The E20 V2.0 has been a disappointment.

    First is the fact that it has no mode memory. You are always starting in low and have work up to high. I must not have gotten the memo. I had assumed, even for an inexpensive light, that there would be a simple memory function. Nope.

    I could have let this issue slide if the runtime on high @ 350 lumens operated as advertised. Anywhere NEAR 3 HOURS would have made this new E20 worthwhile. Unfortunately, I am getting about 10 – 20 MINUTES before the light kicks down to medium @ 150 lumens. Granted, this was with Alkaline batteries. Maybe the performance would be better with Ni-Mh but I doubt it.

    The light has great fit and finish [typical] and a great pocket clip [typical] and good throw – but it is a tiny, under-performer and as such I can only relegate it to Every Day Glovebox status instead of Every Day Carry.

    • Dianne

      We are sorry you are disappointed that this light does not have memory feature. If a light does have this feature, it is listed under “additional features” for the light. If memory is not listed the light does not have it.

  27. Richard (verified owner)

    It’s a good little light, uses AAs, which are always at hand. One switch, three brightness levels, simple. Comes over packaged, lots of plastic, have to wonder what that’s about. The nice bottle of hand sanitizer included – thank you – was not over packaged and the loose lid assured its contents were fully squeezed out.

    Love it, bought 2, one for me and my son. Great edc size, good light throw, good light level options. Would recommend.

  32. Christopher B. (verified owner)

    Finally a suitable “replacement” for my beloved L2D that I’ve been using for probably close to 20yr (?). Not that there is anything wrong with the L2D…still running like a champ!
    I consider the E20 the evolution of the L2D…..smaller, lighter, more powerful…..sounds kind of like the “Six MIllion Dollar Man”…..and a clicky tailcap. What’s not to love???
    Here’s hoping it holds up as well as my will probably outlive me if it does so!
    Let me also add that my L2D lived a very hard life working as an aircraft mechanic….dropped too many times to count! It’s worn down to bare metal in many places. I’m looking forward to many years of service from it’s “little brother”.

  33. David B. (verified owner)

    I like the slim profile and that it uses a regular batter. Works great in my Fenix light lineup.

  34. Jesus (verified owner)

    It’s Fenix!! Need I say more? It’s a great little light at a great price. Highly recommend this for a EDC. The only thing I can suggest for Fenix is producing these awesome products in different colors. “If you produce multiple colors they will come”!

    This is the AA light that I’ve been awaiting for several years.

    Our family has a bunch of Fenix lights, mostly with 18650 batteries. I specifically wanted a AA for the car, though, so I could buy alkalines off-the-shelf in a pinch. I’d been carrying around an ancient Mini Maglite from back when they first switched from halogen to LED. It was better than nothing, but wasn’t bright enough for many applications. Unfortunately, most of the newer AA-powered lights on the market are also relatively dim or have short runtimes, especially with NiMh batteries, despite having more modern lamps.

    I was happy to find an email from Fenix in my inbox one morning announcing the E20 v2.0. The specs are exactly what I’d been waiting for, and the light has lived up to my expectations so far. I haven’t quantified the performance but, qualitatively, it exceeds what I need it to do as an emergency car light. It’s small, bright, emits a nice neutral color, and has an even beam pattern with a balanced spill for short range (e.g. under the hood) and medium range (e.g. hoofing it down the road) applications. It performs well with NiMh, and I like the flexibility and security for my family knowing that we can get batteries at a gas station if our rechargeables run out.

    If you’re new to “real” flashlights and are concerned about the relatively-higher price than what you’ve been paying for junky lights so far, add up the cost of all of those ones sitting in drawers and glove compartments that are not meeting your needs; I’d venture a guess that the E20 costs less than that. Like everything from Fenix, this is a lifetime purchase. Heck, I even broke one of my bicycle lights – entirely my fault – and Fenix replaced it under warranty. After… seven? eight?… Fenix products, I don’t even bother looking anywhere else when I need a light for a new application now. Both the hardware and the customer service are tops. If you’ve bothered to read this whole review, just do yourself a favor and buy the E20; you’ll be glad that you did.

    Very nice

  39. JAY P. (verified owner)

    Overall it is a good looking light. Fits in a shirt pocket well. Light distribution is good. What I don’t like is the 5 position tail switch. The light always starts in low, and you have to keep pushing the switch to increase intensity from there. Otherwise the switch is on or off. For the money I feel the Streamlight protac 1l dual fuel is a better light in a smaller package.

    • Dianne

      Hi Jay, sorry to hear you don’t like the tail switch functionality on this light. Please note that the following sentence regarding the tail switch function of this light is listed in the description on our page:

      “It has a maximum output of 350 lumens and the tail switch operates all functions including on/off and four brightness levels, always starting on low.”

    Best use for AA batteries anywhere! Love the tail tap to change the brightness. Between that and rotary switch are my two favorite ways.

    Smaller and more compact than most 2xAA flashlights. Brighter and longer runtimes than all similar lights in its class. Not a tactical light as it turns on in low, but great EDC light.

  48. Gary H. (verified owner)

    Not as good as my others from Fenix,

  49. Justin Johnson (verified owner)

    One of the previous reviewers mentioned the E16 as their favorite light of all time and I’d have to agree, simply for the creamy warm tint it produces! It’s a dream light. Everyone should own one, or two.

    I decided to pick up the Fenix E20 to keep around the house mainly because of its power source. More than likely it will stay in my tool belt that is used for home repairs throughout the month. There is always something that needs to be fixed around here. We have AA’s everywhere throughout the home and so coming across immediate power is no shortage.

    I will also agree on the tint being ever so slightly greenish but on the last two highest modes it changes to a nice creamy white light. The pocket clip is nice and strong and works great for keeping it where you want it. The tail switch is by far the nicest Fenix tail switch ever. It’s crisp and deliberate. You know when you click it by the sound and touch. They are known for their ultra smooth tail switches and when you use one for the first time, you’ll understand. Anything else you use afterwards will seem like second class.

    I could go on and on about this light but if you’re here and you’ve made it this far, I think you already know it’s the right light for you. The quality is there, the price is there, and the excellent Fenix customer service is there just in case you ever need them. It’s a great light, one that’ll give you many good years of service.

  50. Blade (verified owner)

    Being part of the E series, this light is getting reviewed as such: an every day carry (EDC) light. To start off, it has the same reflector setup as my favorite light of all time, the E16. It makes a soft center and very diffuse surround. This is the most practical setup as it gives you enough practical throw combined with a surround that is wide enough to light up any obstacles in your walking path, helping you to avoid tripping over things. If you point the center beam at the ground about 10 or 12 feet in front of you, the surround will touch your toes. There is simply no better surround beam on the market.

    As for carry ability, this light is much smaller and lighter than the LD22 (another twin AA battery light). It clips in the pocket nicely, doesn’t weigh you down, and you almost forget it’s there. I would say the LD22 is more of a good outdoor light and as such would do a little better carrying on a pack whereas the E20 is truly an EDC. The size and weight are optimized for ease of use and carrying, making it a joy to carry.

    For the tint snobs out there, there is only a small caveat on the first 2 power levels, having a slightly greenish tint. However, at power levels 3 and 4, especially 4, it is a SNOW WHITE beam. To be sure, many many other lights on the market exhibit this same feature at lower power levels, but not all of them have such a nice white beam at higher power levels. I absolutely love it, and unless you are white-wall hunting at low power levels, you will never notice the tint as being a problem.

    The power levels are well thought out and the jump in brightness for each level is linear to my eyes. The tail switch has a very satisfying click and cycling through brightness levels is intuitive. The LED puts out every bit of 350 lumens if not a touch more. There is enough throw to get the job done in every realistic situation that you would carry this type of light for. I can’t imagine anyone expecting to ever need more throw for EDC tasks than this light can provide. If you want a good outdoor light that runs off of AA batteries I would recommend the LD22 instead, having more throw, a tougher body, and an SOS mode.

    As for modes, there are only 4 regular modes with no strobe or SOS feature. I have no problem with this at all and quite honestly I don’t know how you’d practically incorporate such modes with this type of clicky tail switch. Lots of people these days seem to be gravitating away from strobes on lights anyway, me being one of them. The majority of people do not need tactical ability in their EDC light, unless of course you need to throw an inpromptu dance party for your friends. If you need or want a light to blind someone to get away I would highly recommend the E16 as it has an awesome strobe that is easily activated. This light is great for navigation in the dark as well as inspecting anything you’d ever want to.

    If you are concerned about preserving your night time vision, the light does reset to the lowest mode after a few seconds. Personally I may or may not like to see a memory mode for the last mode used, but cycling through the modes is easy enough that this isn’t really an issue. Once your eyes have adjusted to the dark it is no fun getting dazzled, so I can see where this would benefit many people such as night time photographers. Also, I like the ability of a light to be able to tail stand but the awesome clicky switch on this light doesn’t allow for tail stand. In order to get such a great feeling tail switch it is going to NEED to protrude a bit to get that great action, sacrificing tail stand ability. Everything in life is a compromise, and with an EDC type light such as this, it makes sense to compromise tail stand for a better tail switch. I completely understand why Fenix did this and I think others should be aware of this fact. Did I mention I love the clicky tail switch?

    The price is right, the function is ideal for the task at hand, and it runs off of AA batteries. They sell AA batteries everywhere man walks, meaning you will always be able to find power for this great little light. I challenge anyone to find a more convenient light in this form-factor. And with that, I will end by saying CARRY ON.

  51. Frank Whorton (verified owner)

    Great little light for the price. The tapping the tail to change brightness takes some getting used to, but I like it better than a button on the side because you always know where the tail is, but a switch on the side is a different story. I bought it on the excuse that I have 36 AA batteries that will go bad before they are ever used. This is my 12th Fenix purchase, I believe. The only thing I have ever been disappointed with were their bike lights, but that’s a different review. See pics for size comparison.

  52. Fenix Lighting US Product Manager

    Detail review from inside our company on the new E20 V2.0:
    This upgrade from the original E20 provides more light with less throw (wider diffused beam). Why less throw? We really value and need more compact options in our line (and get ready cause more are coming). We felt the 2AA E20 was a better service to our customers with half the weight of the original and a very noticeable 20% reduction in size. Part of making it shorter and smaller required shrinking the depth and width from the original E20 head and reflector. By doing this you dramatically lose your ability to throw light as far. We also used an optical lens to keep any artifacts from showing and making the light as clean as possible when you’re lighting up the darkness. This light is really compact and comfortable in hand or pocket. Light enough to feel comfortable in a shirt pocket (all you EMT take note). We also added a nice pocket clip and adjusted knurling to upgrade the appearance to match our most recent released designs.

    I think this light is the perfect backup flashlight for our members of public safety (MOLLE to vest, clip to shirt pocket) and can be a great light to carry for home, car, toolbox, camping kit, etc. It’s really not going to blow you away with power (of course), but is highly functional in a multitude of your day to day uses (especially close up lighting).

    I’ve been asked to put why I would not buy this light (even though I would). I would not buy this light if I was looking for an option to reach longer targets (see farther). We have plenty of other options in our line for that and I would stick to those. Some of our customers are also going to wish this had a red light AND THIS DOES NOT, so I wouldn’t buy if you’re requiring a red light option.

    I’m biased, but I love the simplicity of this light and would recommend in a heartbeat the combination of a LD30 and E20V2.0 for a powerhouse EDC combo or a PD36R and E20V2.0 for a perfect duty combo within Law Enforcement/Security operations. I hope you all value it as much as I do.
