Our Verdict: Streamlight ProTac HL-X USB
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.
A duty-grade 1,300 lumen tactical light that runs a USB-C SL-B26 pack or two CR123A cells, earning the duty award on ruggedness and dual-fuel flexibility.
What's the bottom line?
Machined 6000-series aluminum with a Type II military-spec hard anodized finish.
Streamlight duty lights have a long field reputation for surviving abuse, which is why it scores top here.
This is the one I would trust to keep working after being dropped on concrete, and the CR123A backup option is peace of mind. It is not the brightest anymore, but 1,300 lumens for a real 90 minutes beats a bigger number that lasts seconds.

Our Analysis, Comparisons, and Test Results
The Streamlight ProTac HL-X USB scored 85 out of 100 overall.
It is strongest on durability and weakest on features.
Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.
Battery Life
Runs the Streamlight SL-B26 protected 18650-class pack with an integrated USB-C charge port, or two CR123A cells as backup.
On the rechargeable pack: High 1,300 lumens for 1.5 hours, Medium 420 for 3.75 hours, Low 70 for 25 hours.
Dual-fuel flexibility means you can drop in CR123A lithium primaries if the pack dies, a real duty advantage.
The 1.5 hour High runtime is honest and steady rather than a brief burst.

| Best in test | 8/10 |

Brightness
1,300 lumens is the High rating and it is far more sustained than the higher-peak lights here, holding about 1.5 hours.
It does not chase a huge burst number, so there is less dramatic thermal step-down.
Here's what that means:
35,000 candela gives a focused, intense beam that reaches out well.
Output is modest against 2,800 or 6,500 lumen rivals, but what it claims it largely delivers.

Cool white tint, tuned for a working duty beam.
