Review: Great Small Inexpensive Keychain Flashlight - 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.
Review: Olight i3E EOS 90 Lumen Flashlight Review - 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.
