The Sofirn SF26 is a handheld tactical flashlight designed for everyday use, offering a powerful and versatile lighting solution. It boasts a maximum output of 2000 lumens and can project a beam up to 964 meters, making it suitable for illuminating large areas like garages or yards. The flashlight is designed for ease of use, featuring a primary switch for momentary or constant-on operation and a separate mode switch for adjusting brightness levels, ensuring that even elderly users can operate it without difficulty.

Function Description:

The SF26 operates with a dual-switch system: a primary switch for power and a mode switch for brightness and special modes. A tap of the primary switch provides momentary on (to the last used mode), while a full press engages constant-on. Another full press turns the light off. When the light is on, a single click of the mode switch cycles through the brightness levels: Eco → Low → Medium → High → Turbo. A double-click of the mode switch accesses Strobe mode, and subsequent double-clicks cycle through SOS → Beacon → Strobe. A single click from any special mode returns to the lighting mode. For quick access to Strobe, the mode switch can be pressed when the light is off, and releasing it turns the Strobe off.

- Low Voltage Protection: Automatically detects low battery levels, drops brightness, and turns off the flashlight when battery voltage is below 2.9V.

Usage Features:

Battery Installation: Before first use, the insulating paper must be removed from the tail cap. When replacing the battery, ensure the positive end faces the flashlight's head.
Battery Level Indicator: After turning on, an indicator displays power status for 5 seconds:
- Green Constant On = Saturated
- Red Constant On = Poor
- Red Flashes = Critical
Charging Indicator:
- Red = Charging
- Green = Fully Charged
Safety Instructions:
- Avoid staring into the beam or pointing it at people/vehicles to prevent retinal damage.
- Keep out of reach of children.
- Strobe mode may trigger seizures in individuals with photosensitive epilepsy.
- High-powered modes will cause the flashlight to heat up, which is normal.
- Ensure proper battery installation with the positive end facing the head.
- Unscrew the light body half a turn during transport or storage to prevent accidental activation and battery drain.
- Never leave the SF26 with its face against any surface (including skin) while in operation, as heat buildup can cause fire, burns, or damage.

Maintenance Features:

Disassembly: Disassembling the sealed head can damage the flashlight and voids the warranty.
Battery Care:
- Sofirn recommends using high-quality brand batteries. Damage from battery leakage voids the warranty.
- Remove the battery if the flashlight will not be used for an extended period.
Thread Maintenance: Every 6 months, threads should be wiped with a clean cloth and lubricated with a thin layer of silicone grease.
Waterproofness: Replace worn-out o-rings with approved spares to maintain the IPX8 waterproof rating.
Troubleshooting: If issues persist after following maintenance guidelines, refer to the warranty policy and contact an authorized distributor.
