i3E

The OLIGHT i3E EOS is a great little EDC flashlight, especially for the price. It’s incredibly small and lightweight, making it perfect for a keychain—you barely notice it’s there until you need it. For such a compact light, it’s surprisingly capable. The 90-lumen output is plenty for everyday tasks like finding something in the dark, unlocking doors, or quick visibility when you need it. I really like that it uses a standard AAA battery, which is included. It’s convenient to be able to swap in a common battery instead of worrying about charging. That said, it did take me a minute to figure out why it wasn’t turning on out of the box—I had to remove the small contact paper that prevents the battery from discharging during shipping. I’ve added this to my keychain as part of my everyday carry, and it’s been a great, reliable backup light. While a rechargeable lithium-ion version would likely be brighter, and something I may consider in the future, this model does exactly what it’s supposed to do. Overall, this is a simple, inexpensive, and highly practical flashlight that’s perfect for everyday carry. Definitely a great value.

I wanted to try a few AA & AAA single cell powered lights to keep handy in my laptop bag and/or on my key chain in my pocket to use anywhere the need comes up, which in my case is a fair bit. After trying a few of these "Every Day Carry" type mini-lights, this is far and away my favorite. It does not have any infrequently used adjustment features I will forgot how to use or which annoy me by coming up in the wrong operating mode, it's smaller than the others I tried out, so it does not add much bulk at all to my key fob (It's dwarfed by either of my 2 car key fobs). Simple twist on/off and a really bright light output. This is a basic EDC flashlight and it excels in that role. And just so I wasn't clear enough, it is really tiny; barely larger than the AAA battery inside. Battery life has been great although I haven't kept track and so far I'm still on my original Alkaline battery installed a few months ago. I rarely use it for more than a few minutes at a time. Sometimes multiple times a day and sometimes not for a week or more. After a few minutes of on time, it will get noticeably warm due to its high light output. That said, if I need a light for much longer than that, it's usually where I need a broader beam and I have bigger and much bulkier units for that. I know a number of reviewers have complained the top has unscrewed and come off, some others have complained it has turned on in their pocket. I keep this in my pocket all day long if I am out of the house and have never even approached either of those issues. I give it less than a quarter turn to turn off and it has never come on by itself or come apart. It's possible those users damaged, lost, removed or had the little O-ring in the wrong groove too far back. It's that O-ring that provides its water resistance and also adds friction to the LED housing that screws on/off and to provide both battery access and the on/off switch function. I haven't gotten it any wetter than from being out in the rain briefly so I can't speak to the water resistance, but I'm not planning on swimming with this or using it underwater. It's rated similarly to other EDC lights, so it should be fine submerged up to a couple of feet deep if the O-ring is intact. Can you break it? I'm sure the answer is yes, but for my purposes and in my pocket, all it's showing is a little wear and tear on the otherwise durable finish from constant rubbing against my keys and pocket change. If and when it ever breaks, I will reorder immediately. To recap - small, did I say small? I meant tiny. - powerful little light for my near distance use (usually within 1-3 feet for me), but the beam will illuminate to quite a distance - Super simple to use and no extra features you probably won't use or don't much matter in a light this small for basic use - Good Battery life, and compatible with NiMH rechargeable AAAs. You can't use a 10440 Li-ion as the voltage is too high for its LED when fully charged, plus it will likely get too hot to hold if you do. If you really need Li-Ion, look to another light. - Inexpensive - Overall a five star for its super convenience, ease of use and function. 2 year update - STILL my favorite! In 2years of use. I've had the top unscrew in my pocket once and have had it turn on once on its own in my pocket. I've maybe missed not having a tail switch vs the twist on/off maybe a couple of times, but the size and weight are just perfect and ditto for light output. I've tried AA size, tail switch types, rechargeables and always come back to this one. Paired with NiMH rechargeable AAA batteries, I usually go for months between battery changes. The others stay handy on my desk or bench, this one lives on my key chain always on my belt or in my pocket and goes wherever I go so I'm never without a light and neither is anyone else who is alongside me at work!

This is a great little keychain, flashlight, and I have nothing to fault it on. The size is perfect and there is just one brightness level of 90 lm which is adequate for lighting up a sidewalk or something in the evening. Granted this is not the most exciting flashlight you will ever pick up but for the price it should be perfect for most people who are looking for a compact and capable keychain light. The fact that it comes with a lifetime warranty and is completely waterproof at this price is also pretty amazing. I like that it has the twist on and twist off design so it will never turn on accidentally in the pocket. There’s nothing about this light that is very exciting but again for the price, size, design, and capability it is hard to knock it.

Purchased 12-13-2016, reviewed 12-7-2017: I have used this now for coming up on a year. It has been in my pocket on a daily basis on my keychain. It is very bright, and I love that it uses a simple AAA battery. I use a rechargeable Eneloop, and it has been super. My only ding of the 1-star was because, as others have pointed out, the head can come unscrewed and you lose the innards of your light, including battery and the bulb. Fortunately for me, it is always in my pocket, rather than hanging on a backpack or belt loop. I have also gotten into the habit, when my hand goes into my pocket, or if I pull out my keys, to tighten the head of the light down to make sure it doesn't come apart, and then back it off a bit to make sure it isn't turned on in my pocket. Since doing that, I've not had it fall apart in my pocket, and I've never found my battery dead because it was inadvertently on in my pocket. But you shouldn't have to do that, hence my one star off. It's very bright and dependable otherwise. UPDATE 12/13/2022: I have now had this little light in my pocket pretty much every single day for 6 years (that's SIX YEARS). To be honest, in the last few years it has been more of my "backup" because in 7/2018, I bought a Streamlight 66118 Stylus Pro 100-Lumen LED Pen Light with Holster (https://www.amazon.com/gp/product/B0015UC17E), and it has become my multiple-use-per-day flashlight. But I probably still use the little Olight a couple of times a week. Since I have the Streamlight on a belt holster, and use it frequently, the Olight probably doesn't need a recharge more than twice a year (on the Eneloop rechargable AAA). Between these two lights, I've never been let down for light when I need it. I've moved up my rating to 4 1/2 stars. I would be tempted to up my review to 5 stars, because it has been such a durable, dependable, convenient, and efficient flashlight on my keychain. But I just can't give it a full 5 stars because of the potential to completely drop all of the pieces, with it's potential to come unscrewed if you don't give it a little check once in a while. But please know that in my book, ANY product of 4 or more stars is a "buy with confidence". You'll notice that my rating for this Olight shows as 5 stars, but that is only because I can't move it up 1/2 star. But the reality is that this tool deserves more than 4 stars, for being so dependable after 6 years. I've bought a number of these as gifts, and in fact have two of them new in the box on my desk and will probably give them as gifts this Christmas. I put my Streamlight and Olight flashlights as some of my most satisfying purchases of all time, their minor faults not withstanding. They have been more durable and helpful than just about any purchase I've ever made, and I would hate to have to live without them.

UPDATE 4/2024: Bought yet another one in the orange. Wish it came in blue, too. This was my backup work flashlight that I kept on my person when I worked at a state park. I often worked in dark-dark conditions and it lit up things nicely when my main 1000 lumen flashlight was less accessible. I now use it at my current job inside a walk-in cooler which has poor lighting and I can't read print all too well on products and boxes. I keep it clipped to my shirt collar, usually a tshirt, on a carabiners attached to one of those retractable ID clips with the little snap closure. Sometimes the little twist on function was a little wonky when I worked at the park, but I was on the move a lot so maybe I wasn't paying 100% attention to my level of twist. Hasn't acted funny at the current job so there you go. Can't be beat for the price, brightness & it's super compact size. AAA battery is pretty decent. Since it was well-used and bonked around a lot at the park, the black finish is currently all jacked up. So bear this in mind if you like keeping your things tip top. I just bought 2 more for my sons to keep on their keys/person when they are out playing/riding around here in the early darkness of late winter on their scooters so they can troubleshoot/lock them up properly if necessary.

Great portabily, size and illumination! Must have!

This is a review of the Olight i3E EOS 90 Lumen Flashlight in Black. I am an enthusiast of flashlights and coolers. This flashlight meets my criteria perfectly well: 1) small as possible, 2) bright, 3) lightweight, 4) uses only 1 aa or aaa battery, 5) is waterproof, and 6) has a simple interface. Positives: 1. This is tiny, even more so than the Fenix E05 (which was already tiny). 2. This is very bright and appears to be about the 90 lumens that it claims. 3. This is even lighter than the Fenix E05. This is the lightest AAA keychain style flashlight that I have come across. You can tell by my reviews, I have had a lot of experience with flashlights. Out of all of the AAA flashlights, this is the first that I do not mind having on my keychain, which is a very lightweight setup. 4. It uses just one AAA battery, which is common in other things such as your remote controls for the television. 5. It has the same o-ring design as other lights in this category with the typical IPX-8 submersible standards. 6. It has the most simple interface, just twist for on and twist back again for off! That is my favorite feature of this light. With other lights, 95% of the time is used on the "high" level. All of my other flashlights, with exception of the Fenix E11 which is my favorite light (too bad it has already been replaced with the E12), require users to cycle between multiple brightness levels along with SOS or Strobe modes to get to your desired setting. This is just simple on-and-off. Negatives: - None. Neutral: 1. The Fenix E11 is my favorite AA flashlight (and overall flashlight) being the smallest AA flashlight I have come across and it has my favorite feature of a simple CLICK of the button switch to turn on and turn off. This Olight i3E is likely my favorite AAA flashlight as it has just one setting of "high" and has one simple step of TWIST tight to turn on and loose to turn off. Both flashlights have a simple one-step interface. However, I prefer the easier to use (especially with one hand) CLICK switch to the TWIST switch. This is just my preference. Some may argue that the twist switch is more reliable, which has merit to it. Other will say that a click button switch can be accidentally activated if bumped into something, which is possible. Lastly, if this flashlight had a click button switch on it, it would likely be longer in length. Despite all of these points, I have found the simple click is easier to use with one hand and I have never had the Fenix E11 accidentally turn on whether in my pocket or in a bag. I have only had this light for a couple of weeks as of March 12, 2016. It is too soon to determine if this is a reliable flashlight, which will require continued use over time. So far, it has been attached to my keychain, which stays in my pocket or gets thrown into a bag for most of the day. An update will be provided in several months to report on how this light does. Previous experiences with the Fenix E05 has been disappointing as at least four of the flashlights that I purchased (for myself and family members) failed within a year's time. These lights were all replaced with the larger Fenix E11, which all continue to work, as does my Fenix LD20. Though the other lights continue to function well, I must admit that the failures of the E05 really hurt my confidence in Fenix. Overall, I rate the Olight i3E EOS 90 lumen flashlight a 5.0 out of 5.0 stars. It is the simplest, tiniest, lightest, single AAA light around. I use it just about on a daily basis. It is the first AAA light that is comfortable enough to have attached to my keychain, which go everywhere with me. UPDATE June 30, 2016: This is easily my favorite AAA light ever. In addition to the black version that was originally purchased, I also picked up the copper version ($20) and two of the silver versions ($13 each). This should show you how much this flashlight is appreciated. My wife took over the beautiful, but heavier copper one. My favorite is the silver version, which I put in our emergency kit. Once again, this is the simplest, tiniest, and most lightweight AAA flashlight I have owned. Best feature, according to my preferences, is the one setting of full power mode. With other lights, too much time is wasted on finding the desired setting. With this one, you know that there is just one full power mode before you even turn it on. UPDATE July 8, 2016: Attached are some pictures to compare the Olight 90 Lumens i3E EOS in black. A size comparison with the 4Sevens Preon 2 in Green, the 4Sevens Preon 1 in solid Titanium, and the Olight i3E EOS in black. The other pictures compare the beam shots for 3 lights in high mode at a 20 inch distance from a white wall (the Preon 2 on the left, the Preon 1 in the middle, and the Olight i3E EOS on the right). I believe Preon 2 claims 192 lumens, Preon 1 was 80 if I recall, and the Olight i3E is 90 lumens.

Very handy... just the right size for my keychain. Very bright light.

Estoy satisfecha y sobre todo por el precio un producto de Exelente luz

Une très petite lampe d'une puissance étonnante pour sa toute petite taille. Construction sérieuse et finition parfaite, autant que la qualité de la lumière qu'elle fournit. Seul petit bémol, la solidité de la partie porte-clef qui semble vraiment juste. A revoir si vous voulez la conserver; elle est si pratique qu'on n'a pas envie de la perdre ! Livraison très rapide et emballage soigné, vendeur consciencieux.
