Are you searching for a small keychain light with some interesting features, and don’t want to break the bank?

This Imini might be for you.

You probably know that Olight makes some high-quality flashlights, headlamps, and other types of lights (penlights, desk lights, etc). But they aren’t particularly known for their smaller flashlights. Yes, they have a few like the Olight i1R 2 EOS, the i1R PRO etc, but this one is really Mini. Let me present you the Olight Imini.

But before we dive into all the testing and details, let’s start with the packaging.

Package quality.

The Imini (why didn’t Olight call it the Omini?) comes in a nice carton board box, which looks similar to the Olight i1R PRO. Inside the box, you will find the following

  • The flashlight: Olight Imini
  • 3 spare LR41 batteries
  • Split ring for on your keys
  • Manual

Flashlight in use

Alright, how do I turn this thing on?

Is there a switch? nope

Do I push the tail? nope

Do I twist it? nope

So how in the world do you turn this on?

In a rather unique way! Olight calls the Imini a quick-release keychain flashlight.

You pull the flashlight out of the tailcap (I just call it a tail cap). The moment you remove the light (which now looks like a bullet) it will turn on. The rear-end of the Imini has a tiny hole with a pogo pin that will activate and deactivate the light.

The built-in magnet is very strong, so you don’t need to worry about accidentally losing the flashlight. Actually, there are 2 magnets, 1 very strong one in the rear end of the flashlight, and 1 weaker one inside the quick-release tailcap.

I don’t know how many lights have this kind of magnetic quick-release tailcap, but the first time I saw it, was on the Lumintop Glow I. It has a similar kind of magnetic tailcap, but you still had to activate the light by twisting it after it was removed. However, Olight skipped that part by having this little pin-switch built-in.

The only way you can comfortably hold it is in between your index finger and thumb.

There’s a split ring at the tailcap of the flashlight so you can attach it to your keys.

So, what is this light for? Probably just as a keychain light, for small emergencies. You can’t really count too much on it, for your EDC light, because the battery life is pretty short.

Build Quality, and Warranty

There’s isn’t much to tell about the build quality, since there aren’t many moving parts. I love the idea of pulling the light out of the ‘tailcap’ and have instant light.

The coating is nice matte, and doesn’t seem to have any problems.

LED, Lens, Bezel, Beam, and Reflector

It’s no surprise that Olight isn’t mentioning what brand and type of LED is used in the Imini.

Just from looking at it, I can’t really tell what it is. But perhaps it’s an Osram P9?

It’s sitting behind an TIR optic, and gets the following CCT, and Ra (CRI) values, when measured with the Opple Light Master pro. I measured from about 20 cm distance.

CCT: 4995K

Ra (CRI): 73.1

In my honest opinion, the beam quality is not really important for this kind of light. Its runtime is so short, that you could only really use it for emergencies or backup. It’s too difficult to replace the batteries on the go to use it as your main EDC flashlight. That being said, the beam isn’t bad at all, and has a nice hotspot, without any artifacts. Just like I have come to expect from Olight. Well done.

Batteries & Charging

Okay, this is a little unusual, and the first flashlight we review at 1lumen.com that uses 3 LR41 batteries. Most other flashlights that run on LR41 batteries aren’t built by popular brands like Olight. So it’s no surprise this is our first review of a flashlight with this type of batteries.

Olight loaded the 3 batteries so you can get started. You just need to remove the insulating film before the first use.

But they also includes 3 spare ones.. and those are necessary for testing. I tried to combine Lumens and Runtime with 1 set of batteries. And throw with the second set of batteries.

Replacing them isn’t very easy, because these batteries are really small. so just keep that in mind! I don’t recommend trying to do this while walking or sitting in a car/airplane/train.

I wanted to see if a 10180 could fit, but nope, its too wide.

Performance test

Lumen measurements:

All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

SpecsLumens @ start@ 30 sec@ 10 min
1011.42 lumens11.139.92 lm

Runtime: Battery life

The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

ModeSpecified runtimeMeasured runtime (ANSI FL1)Time till shut off

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turn on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Throw Measurement: Peak beam intensity and beam distance

Measurements were taken indoors with a Hagner E4-X Lux Meter, at 2 meters.

@ turn on27cd31.6 cd1112.30
@ 30 sec27cd30.4 cd1112.06

Extra info: Peak beam distance according to ANSI FL1 standards: The calculated value of distance in meters at which the flashlight produce a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object).


It’s too weak to compare to any other set of outdoor beamshots I have. So I compared it to the Olight i1R 2 PRO in low mode (specs: 5lm, measured 8.5lm) and the Nitecore Tini2 (15lm).

Disclaimer: This flashlight was sent to me for review at no cost by Olight. I have not been paid to review, nor have I been holding back on problems or defects. 

Final Verdict


  1. Cute little light
  2. Very strong magnetic base, and sticks to everything
  3. Quick-release feature
  4. Includes spare LR41 batteries


  1. Can’t use rechargeable batteries
  2. Maybe a bit too small to use for any serious tasks
  3. Not easy to replace the batteries.

Explanation on star ratings:

1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues; almost unusable – 3: Average: some defects or issues; but still usable 4: Good: recommended (minor issues) – 5: Great: highly recommended

4.5 stars: ★★★★⋆

If you came here to see if this could replace your EDC light, I have to disappoint you. It’s not bright enough for most tasks, and the runtime is very short. But if you came here to have an emergency or backup light for on your keys… read the complete review.

If you get one, keep in mind that replacing the batteries is not particularly easy!
