Sofirn support FAQ

Ajụjụ a na-ajụkarị gbasara akwụkwọ ntuziaka, ndebanye aha na nkwado maka ika a.

  • How do I change the brightness modes on my Sofirn flashlight?

    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.

  • What makes the Anduril UI different?

    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.

  • Are Sofirn flashlights waterproof?

    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.

  • What kind of warranty does Sofirn provide?

    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.

  • Can I use any battery in my Sofirn light?

    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.
