The Sofirn BLF LT1 is a premium rechargeable camping lantern designed for serious outdoor use, emergency preparedness, and extended off-grid lighting. It features 8x Samsung LH351D LEDs (4x 5000K + 4x 2700K, all 90 CRI) that deliver a maximum output of approximately 700 lumens with fully variable tint from warm 2700K to neutral 5000K white light — perfect for creating a comfortable, high-quality atmosphere in tents, campsites, or during power outages.

Powered by four 18650 batteries (button-top, max 70 mm length; not included except in kit versions), the LT1 offers exceptional runtime thanks to its efficient driver and advanced thermal regulation. It includes an integrated USB-C charging port that also functions as a power bank, allowing you to charge other devices when needed.

The LT1 runs open-source Andúril firmware (GPLv3), giving you an incredibly versatile user interface with smooth or stepped ramping, Muggle mode for simplified operation, electronic lockout, battery check, sunset mode, configurable beacon, multiple strobe effects (tactical, party, bike flasher, candlelight, lightning storm), and more. The electronic side switch provides intuitive control, and the lantern is built from durable aluminum with HAIII anodizing.

With an IPX7-equivalent water resistance rating, the BLF LT1 is ready for real-world camping, hiking, fishing, and emergency situations. Its wide-area lantern-style output provides even, comfortable illumination without harsh hotspots.
