ThruNite TN12 Pro vs Olight Warrior 3S Titanium: Two Powerful EDC Flashlights Compared

Introduction

Some flashlights sit comfortably in the every day carry niche, and then there are lights like these two: larger, brighter, and built for people who genuinely need serious output on hand. The ThruNite TN12 Pro comes in at $49, while the Olight Warrior 3S Titanium runs roughly $100 to $120. They share a similar size class but take very different approaches to brightness, heat, and safety, so it is worth understanding where each one fits before you pick.

ThruNite TN12 Pro: The Pocket Thrower

The TN12 Pro is an 18650-powered flashlight claiming 1,900 lumens on turbo, held for about 7 minutes before stepping down to 477 lumens for roughly another 130 minutes. Lower modes include 550 lumens on high, 220 on medium, and 50 on low, plus a half-lumen firefly mode that can run for 37 days. Strobe is included as well. The claimed throw is 380 meters with 36,000 candela, and the light carries a 1.5 meter impact resistance rating along with an IPX8 rating, so it can get wet and go underwater.

At $49, that turbo runtime of 7 minutes is genuinely generous, since few lights hold turbo that long. The trade-off is heat: the TN12 Pro gets hot fast, hot enough that the front of the light becomes difficult to hold and can scorch nearby material. If it switches on in a pocket or holster, the head can burn fabric or skin within a short time, so it needs careful handling.

Operation is straightforward. The rear tail switch gives momentary or full-click turbo, but the tail only controls on and off for turbo. Mode changes happen on the forward switch: double tap for turbo, push and hold for firefly, triple tap for strobe. A rubber-coated USB-C port handles charging, and it charges quickly.

Beam Pattern and Runtime

The TN12 Pro has a big, concentrated hotspot in the center, which makes it a mini pocket thrower. It is the light for looking at things far away, with a clean viewing circle at distance. Up close, that concentration works against it: at 10 to 20 feet the hotspot washes out whatever you are looking at, even though a nice circle forms around the center.

That makes it best suited as a truck light or a work light for longer distances, such as commercial construction or site inspection. If your typical use is 10 to 20 feet, this is not the light you will reach for. Interestingly, despite being the cheaper light, the aluminium TN12 Pro is lighter than the titanium Olight, which makes it easier to carry.

Olight Warrior 3S Titanium: The Safer All-Rounder

The Warrior 3S Titanium takes a broader approach. On turbo it puts out 1,850 lumens for about two and a half minutes, then drops to roughly 35 percent of that for 235 minutes. High is 650 lumens, medium 200, low 15, and there is a one-lumen moonlight mode. Claimed turbo throw is 250 meters with 16,900 candela, and it is also IPX8 rated.

The standout safety feature is the proximity sensor. As an object gets close to the head, the light automatically turns itself down, so it will not burn anything. You can hold a hand right over the head on turbo and the sensor steps the output down. That makes it far more pocket-safe than the ThruNite, though you pay roughly double for that peace of mind.

The light runs on a 21700 battery cell and features a tail switch that doubles as the magnetic charger connection. A light press turns it on at low momentarily, a quick click latches low, and pressing hard quickly engages turbo. The front side switch panel is the highlight: a four-light battery indicator on the right and a mode indicator on the left, so you always know where you stand. The tail and forward switches work together intelligently, letting you move through modes from either end.

As a titanium model, it is heavier than the ThruNite, and the machining on the threads sounds slightly less smooth than Olight’s aluminium models, likely because titanium is harder to work. Still, the finish looks excellent, and the light has clearly been refined over time with upgrades like the new switch panel.

Buying Advice: Which One Fits Your Carry?

These are two genuinely different lights. The TN12 Pro is a thrower: 380 meters of reach, a 7-minute turbo that few lights match at any price, and a $49 cost that reflects a real heat-management compromise. The Warrior 3S Titanium is floody rather than spotlight-oriented, gives a broader, more even spread at close to mid range, and its proximity sensor makes it safe to keep in a pocket or holster. Its price sits between $100 and $120, but the safety and the indicator switch panel go a long way toward justifying it.

If you want maximum distance and output per dollar and can manage the heat, the ThruNite is the value pick. If you want an all-around light that will not cook your pocket, the Olight earns its premium.

Conclusion

Both lights are excellent at what they are designed to do. The ThruNite TN12 Pro is a superb budget thrower for long-distance viewing, while the Olight Warrior 3S Titanium is the safer, more versatile everyday companion. Match the beam pattern and safety profile to how you actually carry a light, and either one will serve you well.
