Olight Warrior Nano
The Warrior series of flashlights are tactical flashlights produced by Olight, one of the world’s leading producers of all types of lights.
Olight is always on top of the game, doing stellar work with innovation and product development. You can bet your bottom dollar that Olight consistently releases new and exciting products and variations featuring fresh designs.
From gun lights to lamps, Olight has got you covered. They have recently begun expanding into developing products like pens and knives, too! The Warrior line of lights gives you incredible versatility for tactical flashlights.
The Warrior X Turbo light will be perfect if you want a big duty-oriented flashlight with a very good beam profile. Say you want a more miniature flashlight. Then, the Warrior Mini light is perfect for you. But what if you want an EVEN smaller light?
If that’s the case, you’re lucky because the Warrior Nano was made with you in mind. This new tactical flashlight takes its place between the Baton 3 Pro and the Warrior Mini, in size and output, producing 1,200 lumens.
Let’s take a closer look at this light!

What Comes in the Package?
Olight packaging is a treat for the eyes, as per usual.
The Warrior Nano comes in a full-size packaging design with a 1:1 scale image of the flashlight on the front and specifications on the back.
Inside the package, you will find:
The above is everything you need to get your light up and running. As per the “Welcome” deal in the box, you must remove the isolator film between the head and the battery driver. When you receive it, the battery is at 3.62 volts, which is a suitable storage voltage.
However, it would be best to recharge it to use the light to its maximum capacity. Regrettably, this dual switch flashlight does not come with extra o-rings. The manual is written in 20 languages, though, which is excellent!
Olight Warrior Nano Build
Build Quality
The Warrior Nano is an excellent tactical and EDC flashlight fit. It is small, light, and fits well in pockets, as you will see when I cover the light’s dimensions.
The light has excellent build quality, design, and finish. There is not even a whiff of quality control issues, and all the parts of the light fit perfectly. Having no sharp edges is essential for a pocket light, and the Olight Warrior Nano has none.
The Warrior Nano features a removable deep carry pocket clip with a unique dual retention clip. The light has a tail switch at the back and a side switch behind its head. The tail switch is metal, magnetic, and flat. It is magnetic so that the MCC charger can be accommodated.
This fun feature also means the Warrior Nano will stick to any magnetic surface at 90 degrees. The light also comes with a metal L-holder. I can hear you thinking right now, “How can a metal L-holder possibly help me?”
It’ll help you immensely in situations when you need to use your light hands-free. You can use the L-holder to hold up your light, and the holder itself can be attached to surfaces.
The flashlight’s front e-switch sits almost close to the body of the light, but it can be located quickly by touch. The rear switch of the light is 2-positioned to facilitate half-turbo or strobe mode. Even with the presence of this switch, though, tail standing is possible, and accidental activation is not a concern.
The Olight Warrior Nano has a semi-matte anodization in type III HA. You can choose from two colors: black and a Halloween limited edition green that’s dubbed “Zombie Green.” There are only 6,000 units of the Zombie Green version, and these lights are green with speckles of red on them.
The Warrior Nano has an IPX8 rating for ingress protection and a 1.5-meter drop rating. Since the o-rings protect the light well, this rating is no surprise. Batteries are inserted from the front, and threads are only present on the front of the tube. The threads are all sized well and rectangularly cut.
The flashlight’s tail has spring-loaded contact with five contact pads to facilitate the tail switch functions and charging interface electrical path. The head of the light has a distinctive electrical path with a gold-plated contact and an internal coil spring.
Overall, the build of this light is top-notch!
LED, Lens, Beam, Bezel, and Reflector
Olight keeps the LED under wraps, so I can’t say precisely what this flashlight uses.
However, I’m willing to guess that the Warrior Nano flashlight uses a cool white emitter, specified by Olight as 5,700-6,700K with a 70 CRI. It is most likely that the LED used here is an Osram P9, as opposed to the Luminus SFT40 used in the Warrior Mini.
It should technically be simple to find a replacement LED for emitter swaps. However, the Osram P9 has a 3737 footprint, which is incompatible with the usual 3535 footprint. Therefore, swapping out LEDs is difficult.
The LED rests beneath a TIR optic, a customized mix of a reflector and TIR. A crenelated strike bezel protects the TIR optic. The light’s beam is clean and perfect for everyday use. The hotspot of the beam is a flat circle, and it has a defined edge.
Dimensions
Here are the dimensions of the Warrior Nano flashlight. The measurements are rounded to the nearest millimeter and the nearest tenth of an inch.
| Millimeters | Inches | |

Olight Warrior Nano in Use
User Interface and Driver
The user interface of the Warrior Nano is typical of the Warrior series.
The side switch controls the light modes, and the tail switch puts the light in Half-Turbo, Turbo, and Strobe modes. As with the rear switches of the other lights in the Warrior line, the tail switch on this flashlight can switch the light on temporarily or entirely, depending on how the switch is pressed.
It can be configured in 3 different ways. The default configuration is Medium and Half-Turbo mode, and the second configuration is Instant Strobe. The last setup option available is for Medium and Turbo modes.
The following are the primary brightness levels available:
The Warrior Nano has the following blink mode available:
Here is what you should do to activate the flashlight when turned off using the side switch:
Using the side switch when the light is already on leads to the following:
Here is how to work the rear switch configuration 1:

To work the alternate rear switch configuration:
Here are the shortcuts you can use with this flashlight:
Here is how the low voltage warnings and protection work in the Olight Warrior Nano:
The steps below should be followed to put the flashlight in lockout mode:
Previous mode memory is available only for Low, Medium, and High modes. The Warrior Nano does not have Pulse Width Modulation (PWM).
The Olight Warrior Nano UI has a lot going on for such a small light. Regardless, it is flexible and easy to get the hang of. Quick access to Turbo and Strobe is essential for a tactical light, so, significantly, this feature is available.
Switching between Configuration 1 and Configuration 2 is also simple to do. To switch to Configuration 2, click the side switch while pressing the tail switch hard. In Configuration 2, Half-Turbo is replaced with Strobe.
To switch from Half-Turbo to Turbo, press and hold the side switch for 2 seconds while the charger is attached. This will cause the light to switch on in Moon mode and enter a lockout state.
Then, you can disconnect the charger from the charge port, unlock the light, and press the tail switch hard to activate it in Turbo. To return from Turbo to Half-Turbo, you must repeat the process.
Charging and Batteries
The Warrior Nano uses an Olight ORB-183C11, 1100 mAh, 18350 cell. This is a proprietary battery with the anode and the cathode on the top of the cell. The cell is well protected as it has under/overcharge and discharge protection.
Now I know what you’re thinking.
Proprietary cell?? Yikes! I would much rather prefer non-proprietary batteries.
The thing is, though, Olight makes its lights with average consumers in mind. And average consumers are not likely to know the ins and outs of using a lithium-ion battery safely. Olight batteries are superb quality, though, so there isn’t much to worry about.
Factory runtimes and outputs also match the specified values since testing was conducted with the included battery. Charging is done through Olight’s MCC charging system, which consists of a USB-A plug on one end and a magnetic pad on the other.
The magnetic pad has two contacts that interface with the tail switch. It is set for 1,000 mA, a safe current for this proprietary battery. If the idea of MCC charging is bugging you and you’re wondering if charging the cell in a hobby charger will work, the answer is yes.
However, keep in mind that Olight does not recommend this.
Olight Warrior Nano Performance
Modes and Lumen Measurements
Lumens were measured under the ANSI FL1 Standards with a 30cm integrating sphere using a Digi-Sense 20250-00 data logging lux meter. The fully charged Olight ORB-183C11 battery was used for testing.
| Mode | Specs | Lumens at turn-on | Lumens at 30 secs | Lumens at 10 minutes |
| Moonlight | 0.5 | 0.8 | 0.8 | – |
| Low | 15 | 14 | 13 | – |
| Med | 60 | 59 | 59 | – |
| High | 400 | 381 | 372 | 367 |
| Half-Turbo | 600 | 563 | 555 | 537 |
| Turbo | 1,200 | 1,129 | 1,102 | 362 |
The figures I measured are slightly lower than specified, which is unusual for an Olight flashlight. However, these are still good results for such a small light.
Battery Life
Runtimes were measured using a 30cm integrating sphere with a Digi-Sense 20250-00 data logging lux meter. Temperature readings were measured using a Digi-Sense 20250-92 data logging thermocouple. The Olight ORB-183C11 battery was used for the test.
| Mode | Specified runtime | Measured runtime ANSI | Time till shut off |
| High | 2 hrs 5 mins | 2 hrs 5 mins | 2 hrs 7 mins |
| Half-Turbo | 1 hr 25 mins | 1 hr 25 mins | 2 hrs 00 mins |
| Turbo | 1 hr 20 mins | 1 hr 21 mins | 2 hrs 1 min |
The runtimes I measured match up perfectly with those specified by Olight, which is no surprise. The light’s driver is well-regulated and delivers laminar output with no fluctuations as the battery runs out of juice.
Beam Intensity and Distance Measurements
The test for beam distance was done using a Uni-t UT383S lux meter at a distance of 5 meters. A fully charged Olight ORB183C11 was used for the test. Measurements were taken at 30 seconds as per ANSI specifications.
| Mode | Specs | Candela measured | Meters | Yards |
| Moonlight | N/A | N/A | – | – |
| Low | 65 cd | N/A | – | – |
| Medium | 262 cd | 177 cd | 27 m | 29 yd |
| High | 1,577 cd | 1,628 cd | 83 m | 90 yd |
| Half-Turbo | 2,304 cd | 2,529 cd | 102 m | 111 yd |
| Turbo | 4,697 cd | 4,881 cd | 141 m | 154 yd |

Final Thoughts
As always, Olight blows all its competition out of the park with the Warrior Nano.
This flashlight strikes the perfect balance between high performance, bright output, and compactness. It gracefully takes its place between the Warrior Mini and the Warrior 3S and is more tactical than the Baton line.
Among the many plus points of the Warrior Nano, its consistent laminar output, dual switches, the two-stage tail switch, and memory function take the cake for me.
You have my word; this is an ideal flashlight for anyone looking for a small flashlight that will not disappoint!
