Best Tactical Rechargeable Flashlight
Olight Warrior 3S
Bottom Line : A well-regulated dual-switch tactical light with a big 5,000mAh cell, dinged only by a proximity sensor that dims it at the wrong moment and proprietary charging.
Pros
- Large 5,000mAh 21700 cell
- Well-regulated 800 lumen sustained output
- Dual-switch tactical interface
- Proximity sensor prevents overheating
Cons
- Proximity sensor can dim it unexpectedly
- Proprietary MCC3 magnetic charging only
- Grey anodizing wears relatively easily
Our Verdict: Olight Warrior 3S
A well-regulated dual-switch tactical light with a big 5,000mAh cell, dinged only by a proximity sensor that dims it at the wrong moment and proprietary charging.
A 2,300 lumen dual-switch tactical light on a customized 21700 5,000mAh cell with a proximity sensor, earning the tactical award on regulation and runtime.
So, is it any good?
The 2,300 lumen Turbo is a short burst; the light steps down to a regulated 800 lumens after about 2.5 minutes.
Reviewers note a well-regulated driver with no visible PWM, so the sustained output is steady not flickery.
The regulation is excellent, 800 lumens held rock steady for hours on a search. My one gripe is the proximity sensor dimming the beam when I bring it near my hand, though a double-click sorts it.

Our Analysis, Comparisons, and Test Results
The Olight Warrior 3S scored 86 out of 100 overall.
It is strongest on brightness and weakest on beam quality.
Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.
Battery Life
Powered by a customized Olight ORB-217C50 21700 cell rated 5,000mAh, larger than most rivals here.
Turbo 2,300 lumens runs about 2.5 minutes, then 800 lumens for 160 minutes, then 250 for 39 minutes.
The sustained 800 lumen level for over 2.5 hours is a genuinely useful working runtime.
Charging uses Olight's MCC3 magnetic cable, which does not accept older MCC cables, and takes about 3 hours.
| Battery Life | Rating |
|---|---|
| Best in test | 8/10 |
| Olight Warrior 3S | 8/10 |
| Category average | 7.6/10 |
| Worst in test | 6/10 |
Brightness
The 2,300 lumen Turbo is a short burst; the light steps down to a regulated 800 lumens after about 2.5 minutes.
Reviewers note a well-regulated driver with no visible PWM, so the sustained output is steady not flickery.
You might be wondering:
The proximity sensor will cut brightness when it detects an object close to the head, which can dim it unexpectedly.
You can double-click to temporarily disable the sensor when the drop is unwanted.

What Other Rechargeable Flashlights Should You Consider?
Not sold on this one? A few others from our testing are worth a look.
The Fenix PD36R Pro is our best rechargeable flashlight overall. The most complete tactical EDC here, with a genuine 21700 cell, USB-C, and a beam that stays usable long after the turbo burst fades.
The Streamlight ProTac HL-X USB is our best duty rechargeable flashlight. The toughest and most dependable light here, with a throwy duty beam and the flexibility to run rechargeable or CR123A cells, though its peak is modest by 2026 standards.
The Nitecore EDC29 is our best brightest rechargeable flashlight. The brightest peak in the group by a wide margin, but that 6,500 lumen figure is a headline burst measured in seconds, not a way to actually light your path.
