The Olight i3T EOS Flashlight is a sleekly designed flashlight with a design slightly more significant than the i3T keychain light. It’s got more lumens than most lights its size and easily fits in one’s pocket, making it great for EDC (Everyday Carry). 

This device also comes with a new tail cap and switch, featuring a dual direction pocket clip. All in all, it’s quite the big deal for something so little, and you can learn more about why that’s the case by reading below:

What Comes in the Box?

To start things off simple, let’s discuss what comes in the packaging. Here’s everything you get in the Olight i3 T’s box:

  • It contains the Olight i3T EOS Flashlight, which uses a Philips Luxeon TX emitter. 
  • It comes with a user manual for the i3T EOS, which features 17 different languages.
  • It comes with a warning card that covers helpful safety precautions.
  • It comes with a single AAA battery, specifically the GMCELL ‘AAA’ Alkaline Battery.
  • An installed dual direction pocket clip.

Packaging and User Manual

The packaging is made out of reinforced card stock. The material is fool-proof and highly durable, making good first impressions before the i3T is even out of its box. 

The user manual is straightforward, which is a great thing. It’s just one page with instructions on both sides, including convenient diagrams. These make everything much easier to understand for beginners, unlike other lights with lots of features that might make things confusing for some.

All the Features and Specifications in Detail

  • It comes with two different modes of operation. A “high mode” and a “low mode.” High mode offers total output at 100% at a severe expense to the battery, whereas low mode offers just 3% output without eating through batteries. 
  • The output in high mode is 180lm and 5lm in low mode.
  • It comes with a waterproof rating of IPX8. 
  • It can spread a balanced beam of up to a distance of 65 yards at the highest setting.
  • It has a light intensity of 900 candelas. Compatible with the following batteries: 1.5V AAA Alkaline batteries, 1.2V AAA NiMH batteries, and 1.5V AAA Lithium batteries. Finding a new battery is easy enough as there are many AAA batteries to choose from. But, it’s not compatible with rechargeable lithium batteries.
  • The durable design makes it resistant to impacts of up to 1.5 meters in the distance. 

Physical Dimensions, Weight, and Size

  • The total width of the head is 15.01 mm.
  • The length of the device is 85 mm. This changes to 88.88 mm when you include the protruding tail switch.
  • The grip area is 15.01 mm, just like the head.
  • The total width of the tail cap is 14.99 mm.

The weight of this flashlight depends on whether you have an AAA battery inside or not. For example, its total weight is just 39g grams, which is easy to carry around. With an alkaline battery and the pocket clip included, this shifts to 66 grams

That’s still pretty light, especially when you consider all the features it has to offer. 

Analysis on Build Quality and Disassembly

There’s not much to say about the build quality of the Olight i3T. It’s simply exceptional. The body is a treat for carrying. It has perfect size and durability and comes with a grip better than most flashlights. 

The color and materials are also great, which is a bonus. The main material used in production of the light is aluminum.

Everything about this device is crafted expertly, from the tail switch to the tail stand. The only real complaint some people might have is the clip. Unlike the rest of the device, it has a much weaker build and easily breaks if you aren’t careful while taking it off.

You might notice that the device has a little QR code on its body, which has an affiliate link associated with it. If you scan this, it simply takes you to the Olight i3T EOS serial number you own. It comes with a double helix design, like other versions of the i3T EOS.

As for the disassembly part, the only removable part of this device is its tail cap. Further disassembly requires tools and extra components, which can be difficult and cause damage if not done correctly. 

So, if you want to swap parts around, such as the cool white emitter or other components, make sure to do so with care and caution.

User Interface and Ease of Use

One of the best things about this device is its ease of use. Lots of flashlights with multiple features make things too difficult for beginners, but that’s not the case with this one. That’s because the Olight i3T EOS uses a forward clicky switch for most of its functionality.

The switch is there to power the flashlight on and off. But, it’s also for switching between the different modes. You can adjust this device’s AAA lights and modes through a half-press and following the user’s manual instructions.

While it’s off, a single click will turn the light on. To turn it off while it’s on, just click it once. Half-click the device once to put it on low mode, and do it twice in quick succession to switch to high mode.

The best part is that it is also comes with mode memory. This is a convenient feature, as you don’t have to revert to your last-used mode each time you turn the device off to save power.

It also offers options for hands-free usage, as you can use the clip to attach it to your shirt or a hat. That way, you can work in tight spaces while having both your hands at your disposal. 

Generally speaking, the Olight i3T EOS is an excellent option for most people because it is easy to use.

How Good is the Battery? Along With Battery Replacement

It has a GMCELL ‘AAA’ Alkaline Battery installed inside. But, you can also use one of the battery types we’ve already discussed instead if you want to replace it. The battery is decent, as it lasts nearly 18 hours on low mode.

However, the story is much more different when switched to the highest setting. That’s because it lasts less than half an hour on these settings, which is understandable given the high intensity compared to the small size of the battery and the device itself. 

The Price of the Olight i3T EOS: is it Worth it?

How much do all of these great features and specifications cost you? Most people would assume lots of money, but that’s not the case. This device costs only 19.95, which isn’t expensive.

So, the answer to the question, “is it worth it?”? For us, it’s a resounding yes because of this flashlight’s build quality, features, lighting, and overall functionality. 

It’s an excellent option for anyone that needs a new flashlight for everyday use, regardless of how much experience they already have with one.

What makes things even better is it’s pretty much entirely risk-free. That’s because you can get a five-year warranty with this flashlight, a further promise of its good durability and long-lasting quality.

While there isn’t a refund policy, Olight still offers customers free repairs or replacements at any time while the warranty lasts. Even after those five years, the brand provides discounts to those who want a new Olight flashlight after their previous one wears out.

Things to Like

  • One of the best, most likable things about this light is its size. It’s perfectly sized so as not to be too small, but also not so big that it’s a hassle to carry around. You can easily take it with you and use it for any job you need.
  • The tail switch, tail cap, and tail stand are all excellent components of this flashlight. They’re super easy to work with, and anyone can make the most of them, even if they’re new to using flashlights like these. 
  • A subtle thing many people skip over when it comes to the Olight i3T is its sleek design. The curves aren’t there just for show. They’re helpful additions to the flashlight that provides firmer gripping, making it a reliable light in tight situations.
  • Many people aren’t sure whether to spend big bucks on something as simple as a flashlight. But, sometimes, the investment is more than worth it. If you’re still scared about wasting money, you’ll be glad to know that it comes with a five-year warranty.
  • Unlike most lights that are its size, the Olight i3T has excellent light intensity. Do we need to say why that’s a massive advantage in a flashlight?

Things to Dislike

Not every detail about this product is an amazing one. There’s some stuff many would dislike too, such as:

  • The most significant disadvantage of this product we can think of is the lack of lithium-ion support. You can’t use 10440-sized rechargeable lithium batteries with it, which is a substantial preference over alkaline batteries for some.
  • The battery life isn’t too bad, but certain drawbacks make it worse. For example, there’s no lock system on this device. If it accidentally turns on while moving around in your pocket or some other way, the battery will drain away without you knowing. 
  • Not everyone likes having a pocket clip on their flashlight. Unfortunately, if you’re one of these people, the Pre-Attached Dual Direction Pocket Clip on this device is difficult to take off without breaking it completely. Probably don’t try that unless you’re willing to take the risk of damaging the device.
