If you're an outdoor enthusiast or simply in need of a reliable light source for everyday tasks, the Sofirn HS41 right-angle flashlight is here to meet your high-performance lighting needs. Equipped with four LUMINUS SST-20 LEDs, this powerful flashlight boasts a maximum output of 4000 lumens, making it the perfect companion for camping, hiking, and all your exploration endeavors.

Crafted from A6061-T6 aluminum alloy, the HS41 is built to withstand the rigors of outdoor adventures. Its rugged design ensures durability and longevity, while the IP68 waterproof rating ensures it can handle the harshest weather conditions without a hitch.

At its core, the HS41 is powered by a single 21700 battery, providing ample power for extended usage. With a working voltage range of 2.7V to 4.2V and a standby drain of less than 130uA, the flashlight delivers efficient performance that maximizes battery life.

Charging the HS41 is a breeze, thanks to the Type-A to Type-C 5V 3A input, which allows for a maximum charging current of 3A. With swift and convenient charging capabilities, you can quickly get the HS41 ready for action whenever needed.

The HS41 comes equipped with a smooth reflector and a toughened glass lens, delivering a spotlight beam angle of 25° and a floodlight beam angle of 96°. This combination ensures a versatile illumination that can cater to various lighting needs, whether you're focusing on distant objects or illuminating a wide area.

One of the standout features of the HS41 is the magnetic tail cap, which offers hands-free convenience by allowing you to easily attach the flashlight to metal surfaces. This magnetic feature proves invaluable in various situations, such as car repairs, campsite setups, or even just hands-free reading.

When it comes to performance, the HS41 is more than just powerful; it's also intelligent. Featuring Advanced Temperature Regulation (ATR) technology, the flashlight automatically adjusts the brightness level to prevent overheating when the temperature rises, ensuring a safe and efficient operation.

The HS41 is also designed with user-friendly protections in mind. The flashlight features Low Battery Protection, which detects the battery level upon turning on the flashlight and automatically switches to a lower output mode if the battery is low. This feature guarantees you never find yourself in the dark unexpectedly.

Additionally, the Low Voltage Protection feature ensures the flashlight's output is disabled if the battery voltage drops below 2.7V in eco mode or moonlight mode. This safeguard ensures you preserve your battery and avoid power depletion during critical moments.

The HS41 also comes equipped with Reverse Polarity Protection, providing built-in protection against incorrect battery installation, adding an extra layer of safety to your lighting experience.

To keep you informed about the battery's status, the HS41 features Voltage Warning. When the battery voltage falls below 3V while the flashlight is on, the indicator will flash red, and the flashlight will vibrate twice at one-minute intervals. This notification system alerts you to insufficient battery power, allowing you to take prompt action.

With a size of 30.129115mm and a lightweight design weighing only 79g (without a battery), the HS41 is compact and portable, fitting comfortably in your pocket or backpack for easy carry.

In conclusion, the Sofirn HS41 is a formidable right-angle flashlight that excels in performance, durability, and user convenience. Whether you're embarking on outdoor adventures or simply navigating through everyday tasks, the HS41's powerful illumination and thoughtful features make it an indispensable companion that you can always rely on.
