Common questions about manuals, registration, and support for this brand.
Operation varies by model. Many Sofirn lights use a side switch where holding the button cycles through Low, Medium, and High, while a double-click activates Turbo. Models with the Anduril UI use 'smooth ramping' by holding the button.
Anduril is an advanced, open-source firmware found on some Sofirn models (like the BLF LT1 and SP36). It offers highly customizable features, including smooth ramping, candle mode, lightning storm mode, and battery voltage checks.
Most Sofirn flashlights are rated IPX8 or IP68, making them resistant to water submersion up to 1-2 meters. Specific diving models (SD series) are rated for much deeper underwater use (e.g., 100 meters). Always check the manual for your specific model's rating.
Sofirn typically offers a 1-year warranty for flashlights and a 6-month warranty for batteries purchased directly or through authorized retailers. Contact service@sofirnlight.com for claims.
Sofirn lights generally require specific button-top Li-ion batteries (18650, 21700, or 14500). Using incompatible or flat-top cells may result in poor connection or damage. Always use sufficient amperage cells for high-output models.
