User Manual
The Sofirn LT1S is a compact and highly practical rechargeable camping lantern designed for tent lighting, hiking, fishing, power outages, and everyday emergency use. It combines 36 white LEDs (18× 2700K warm white + 18× 6500K cool white) for fully variable tint from warm to neutral daylight, plus 4 dedicated red LEDs for night-vision-preserving illumination that also reduces insect attraction.
Delivering up to 500 lumens of white light with a useful 18-meter beam distance, the LT1S is bright enough for cooking, reading, or setting up camp, yet efficient enough for multi-day trips thanks to its buck driver and single high-capacity 21700 battery. The lantern features a convenient USB-C charging port that doubles as a power bank, allowing you to charge phones or other devices in the field. Four LED indicators clearly show remaining battery level during use and charging progress.
A sturdy stainless steel hanging hook lets you suspend the lantern from tent poles, tree branches, or gear. The body is built from aerospace-grade aluminum with Type III hard anodizing for durability, and it carries an IPX8 waterproof rating (submersible to 2 meters) plus 1-meter impact resistance.
The user interface offers mode memory for white light levels and separate intuitive control for red light modes (including strobe and SOS). Advanced thermal regulation automatically steps output down when needed to protect the lantern and maintain performance.
