Powerful Illumination for Outdoor Use
The Sofirn SR15 features four SFT25R white LEDs with a color temperature of 6000-6500K, delivering a maximum output of 4500 lumens with a beam throw of 510 meters, powered by an included 21700 Li-ion battery (5000mAh). It offers multiple modes, controlled by a side e-switch, with the following lumen outputs and runtimes:
- Turbo: 4500 lumens for approximately 1 minute (steps down to around 600 lumens)
- High: 1000 lumens for approximately 2 hours
- Medium: 400 lumens for approximately 5 hours
- Low: 70 lumens for approximately 15 hours
- Moonlight: 1 lumen for approximately 410 hours
- Strobe: 4500 lumens (runtime not specified)
- SOS: 4500 lumens (runtime not specified)
- Beacon: 4500 lumens (runtime not specified)
The flashlight charges via a built-in USB-C port in about 2.5 hours with a 5V/3A charger, featuring a battery level indicator that displays power status for 5 seconds after turning on (green for 70-100%, red for 30-70%, red flashing for 1-30%). It is IP68 waterproof (submersible to 2m) and includes a buck driver circuit for stable output, though it may get warm on Turbo, requiring careful handling.
Durable and Compact Design
The Sofirn SR15 is constructed from aluminum alloy with a Type III hard-anodized finish, offering durability for rugged outdoor conditions like camping or tactical operations. It measures 130mm in length (5.12 inches) with a diameter of 40mm (1.57 inches), weighing 128g without the battery (approximately 180g with the included 21700 battery), making it suitable for EDC or bag carry. The flashlight features a crenulated bezel, a pocket clip for secure carry, and a lanyard hole for added security, though the clip may snag on fabric, suggesting careful placement.
Designed for Outdoor and Tactical Use
The Sofirn SR15 4500 Lumen 510m Throw Rechargeable Flashlight with 21700 Battery for Outdoor Use is tailored for campers, hikers, and tactical users needing a reliable, high-output light for outdoor activities, emergencies, or tactical scenarios. For example, its 510m throw can light up distant targets during a search, while the 410-hour Moonlight mode ensures extended use for reading, though the side e-switch UI requires practice to navigate modes (e.g., long press for Moonlight, double-click for Turbo), and the lack of a lockout function necessitates unscrewing the tailcap to prevent accidental activation. The IP68 rating, USB-C charging, and power bank capability enhance its reliability, but users should avoid direct eye exposure due to its intensity. The SR15's affordable price, included battery, and long-range performance make it a practical choice for outdoor scenarios, offering a balance of power and convenience, though users should plan for UI familiarity and heat management.
