Olight Warrior X 4 review

We have not tested this flashlight, own none of the products on this site, and have no laboratory. This review works from what Olight publishes through its retail listing and the ANSI FL 1 arithmetic that follows from it.

The Warrior X 4's published figures put it in an unusual position: 630 meters of reach from 2,600 lumens is the longest published throw of any light we cover that you could still reasonably use in a building. That middle position is the whole argument for it, and it is a better argument than the specification sheet alone suggests.

What Olight publishes

Two numbers and a charging method. Olight is in the same disclosure group as Nitecore on this site — the headline figures are there and nothing underneath them is. Our Olight versus Streamlight comparison sets out how wide that gap is when you put the two spec sheets side by side.

The beam, computed

38 candela per lumen is the interesting number, precisely because it is moderate. A Streamlight ProTac HL-X sits at 27, a dedicated thrower like the Nitecore P30i at 125, and the Acebeam L19 at 256. The Warrior X 4 is tighter than a duty light and far looser than a thrower.

In practice that means a hotspot with real spill around it. You get most of the reach a thrower offers and you keep enough peripheral light to walk down a hallway without the tunnel effect. For most people who think they want a thrower, this is the beam they actually want.

Magnetic charging: a real advantage and a real dependency

Whether that trade is right depends entirely on how you use it. For a light that lives in a vehicle next to its own cable, magnetic charging is strictly better. For a light that travels, it is a single point of failure you are choosing to accept.

2,600 lumens and the heat problem

An LED converts most of the power it draws into heat rather than light, and a flashlight has nowhere to put that heat except its own body and then your hand. Every high-output light therefore steps down, usually within two to five minutes, and the driver does it automatically to protect the emitter.

This is why the missing runtime matters more on a 2,600-lumen light than it would on a 600-lumen one. The question is not whether the Warrior X 4 steps down — it does, they all do — but what level it settles at and how soon. A light that holds 900 lumens indefinitely is a better tool than one that flashes 2,600 for ninety seconds and drops to 400, and the two are indistinguishable on Olight's published sheet.

For contrast, Streamlight publishes 1.5 hours at the ProTac HL-X's 1,300-lumen high and Fenix 3 hours 30 minutes at the PD36R Pro's 2,800. Both of those are measured to the FL 1 threshold, so they include the step-down — which is exactly what makes them useful. How runtime is defined sets out the 10 percent rule that makes those figures comparable.

Where it sits in the tactical field

The Warrior X 4 reaches furthest of the five and is the only one of the top three that publishes nothing about endurance. The Nitecore P20iX is the instructive row: 4,000 lumens, the most output in the set, and 221 meters, the least reach — because at 3 candela per lumen it is a flood wearing a tactical body.

Against the Fenix, the trade is explicit: the PD36R Pro gives up 250 meters of reach and gives you a published 3 hours 30 minutes at 2,800 lumens, a 21700 you can replace, and USB-C. Against the Streamlights, you gain output and distance and lose per-mode runtimes, IP ratings and impact figures. Our tactical field ranks the whole set.

What cannot be said about it

• How long it runs. No runtime at any level and no battery capacity, so neither the figure nor the arithmetic exists. On a 2,600-lumen light, sustained output is the question that most needs answering and it is unanswered.
• Whether it survives weather. No ingress rating. Not evidence that it fails, but an unknown on a light sold as tactical.
• Whether it survives a drop. No impact figure, where ANSI FL 1 specifies a test and Streamlight publishes 2 m on comparable lights.
• What it weighs, which on a light you carry is the specification you notice first.

Four blanks is a lot for a light in this bracket. It is the reason this review cannot tell you the Warrior X 4 is the best light in its class — only that its two published figures describe something unusually well judged.

Who should buy something else

Skip it if you need maximum reach. The Nitecore P30i publishes 1,000 m and the Acebeam L19 1,300, both with far tighter beams and far less usable spill. See throwers.

Skip it if you need documented durability. The Streamlight ProTac HL-X publishes IP68, 2 m impact, a per-mode runtime and a weight range, and runs on its pack or two CR123A primaries.

Skip it if you travel with one light and one cable. The proprietary magnetic charger is the wrong dependency for that, and a USB-C light is the right one.

Skip it if you work only indoors. 2,600 lumens with a concentrated hotspot is more light than a building needs, and a 600-lumen pocket light will be pleasanter to use. Our EDC field covers that end.

The verdict, stated as what it commits to

Olight commits to 2,600 lumens and 630 meters, which computes to about 99,200 candela and 38 candela per lumen. That combination — real distance without surrendering the spill — is the most broadly useful beam in our tactical set, and it is the reason to buy this rather than a dedicated thrower you will find frustrating indoors.

What Olight does not commit to is runtime, weather sealing, impact resistance or weight, and it ties you to a charger only it makes. Buy it for the beam, with your eyes open about the sheet. If published evidence is what you are buying, Streamlight is the brand on this site that provides it.
