Sofirn SR15 21700 Torch

The SOFIRN SR15 is a high-performance, long-throw flashlight engineered for users who demand maximum brightness, reliability, and versatility in demanding environments. Designed for outdoor adventurers, hikers, campers, search and rescue teams, and professionals requiring a robust lighting solution, the SR15 delivers exceptional illumination with a powerful 4500-lumen output. This intensity is achieved through four high-efficiency SFT-25R white LEDs, producing a crisp, daylight-balanced beam with a color temperature of 6000–6500K—ideal for accurate visual perception in low-light conditions.

One of the standout features of the SR15 is its impressive maximum throw distance of up to 510 meters. This long-range capability makes it exceptionally effective for night hiking, wilderness navigation, spotting distant objects, or signaling in emergency situations. Whether you're scanning a forest at night, surveying a remote trail, or needing to communicate over long distances, the SR15 ensures visibility where other flashlights fall short.

The flashlight offers five distinct brightness levels, ranging from a low 1 lumen for stealthy night navigation to full power at 4500 lumens, with a smooth stepless dimming function that allows for precise control over light output. This flexibility means you can conserve battery life during routine use or unleash full power when needed. Additionally, the SR15 includes three emergency lighting modes: Strobe for distress signals, SOS for standard distress calls, and Beacon for steady, visible signaling—essential for safety in emergencies.

Built with a robust Buck Driver circuit, the SR15 maintains consistent brightness even under high load, preventing thermal drop and ensuring stable performance. This intelligent circuit design also protects the LEDs and battery from overheating or over-discharge, significantly extending the lifespan of the device. The flashlight is fully sealed and rated IP68, meaning it is dustproof and can withstand immersion in water up to 1.5 meters for 30 minutes—making it reliable in harsh weather, rain, or accidental submersion.

Charging is quick and convenient via a USB Type-C port, supporting up to 5V/3A input for rapid recharging. The SR15 uses a single 21700 lithium-ion battery, which provides high capacity and extended runtime. What sets it apart is its dual functionality: the flashlight can also serve as a power bank, allowing you to charge your smartphone, GPS device, or other USB-powered gear in an emergency—making it an indispensable tool for off-grid adventures.

Compact and lightweight at just 128 grams (without battery), the SR15 fits easily in a pocket, backpack, or gear bag. The flashlight includes a memory function that remembers your last used brightness level, and a lockout mode to prevent accidental activation—ideal for storage or transport.

Whether you're exploring remote trails, conducting nighttime operations, or preparing for unexpected emergencies, the SOFIRN SR15 combines extreme brightness, long-range visibility, and smart features into a single, reliable, and compact tool. It’s a top-tier choice for anyone who values performance, durability, and adaptability in their outdoor lighting equipment.
