Olight i3E EOS 90 Lumen Flashlight Review

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.

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.

- None.

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.

Good Flashlights / Cheap AAA Battery

I would recommend the flashlights but the battery that came with it is cheap and doesn't last but a week. I would recommend you use Duracell or other top brands and you get much better performance and longevity.

Small but Powerful

Great little flashlights. I love how they run off AAA batteries and fit easily in your pockets. I bought a few as gifts for friends and family.

Highly Recommended Pocket Flashlight

I love these pocket flashlights! I bought the black version and soon after using it for a few weeks, I ended up buying the blue and green colors. They make excellent gifts for the holidays and work very well. The best thing is they only use 1 AAA battery which you can get anywhere.
