The Problem: That Sinking Feeling When the Power Dies
Sodium Flashlight
When your battery dies in deep winter, it’s more than an inconvenience. It’s a moment of real vulnerability. Whether you’re stuck in a snowed-in town or pulled over on a frozen highway, the last thing you need is for your flashlight to fail too.
Conventional flashlights use lithium-ion batteries that weren’t made for the cold. They slow down, dim out, and eventually shut off completely.
We fixed that.
The Solution
Built for Winter. Powered by Sodium-Ion.
We asked a simple question: What if a flashlight was designed with one goal in mind, working flawlessly in the cold? Not as a feature, but as its core purpose. The result is Sodiumfrostglow.
Performance at -40°C
While lithium fails below -20°C, our sodium-ion cells deliver stable, full-power output at -40°C. A fundamental shift in winter reliability.
3,000 Charge Cycles
Engineered for the long haul. Used regularly for over a decade before significant capacity loss. A permanent part of your safety kit.
Zero-Voltage Recovery
Forget battery anxiety. Our cells can be safely recharged from 0%, even after being stored fully discharged for extended periods.
Feature 01
Your Family's Power Reserve: 10,000mAh
During a blackout, it's more than a light. It's a mobile power station that can illuminate a room for an entire night and still have enough power to keep your phone alive.
Feature 02
2500 Lumen Adjustable Beam
From a focused spot to check the fuse box in the basement to a wide flood to light up the living room—all with a simple, intuitive slide zoom.
Feature 03
Honest Durability & Precision Body
We built Sodiumfrostglow with robust T6063 aluminum alloy and IP44 splash resistance to confidently handle household drops, snowy walks, and life in your car. Lightweight. Solid. Built to last.
3rd Party Certification: The Cold, Hard Facts
We believe that exceptional claims demand solid proof. We submitted our sodium-ion cells to independent labs under strict IEC standards (Report No.: E-NJ24090069A0).
Our Commitment to Transparency
Data Verifiability
Every figure in our charts is authentic, extracted from a complete third-party test report.
Future Verification
Production batches will be sent to a leading North American outdoor-gear testing institute for public evaluation.

About Us: Forged by -40°C
We didn't just read about the cold; we lived it. As two founders who endured the brutal winters of Saskatoon, Canada, we know the feeling firsthand: the sting of -40°C air, the howling winds, and the profound silence when your last piece of gear fails in the dark.
This became our obsession. We saw the need for dependable energy and the limits of existing solutions. So we turned to sodium-ion technology—a power source that defies the cold and respects our planet. Sodiumfrostglow was born to bring unwavering light to the world's iciest corners.
