Sofirn SC18 SST40 18650 Torch

The Sofirn SC18 is a high-performance, pocket-sized flashlight engineered for everyday carry (EDC) and demanding outdoor adventures. Despite its compact size, it delivers an impressive 1,800 lumens of bright, cool white light, making it ideal for night walks, emergency situations, search and rescue, or illuminating large outdoor spaces. Thanks to its advanced Luminus SST-40 LED and precision TIR (Total Internal Reflection) lens, the SC18 produces a smooth, balanced beam profile—offering a sharp, focused hotspot for long-distance visibility and a generous spill for peripheral illumination. This ensures you’re not just seeing far, but also have clear visibility of your immediate surroundings.

Designed with practicality in mind, the SC18 weighs just 55 grams without the battery, making it easy to carry in a pocket, backpack, or on a keychain. Its sleek, ergonomic form is crafted from aerospace-grade 6061 aluminum alloy, hard-anodized for scratch resistance and enhanced durability. The double knurling on the body provides a secure, comfortable grip even in wet or cold conditions, while the solid construction ensures it can withstand drops and impacts during rugged use.

The flashlight features a user-friendly side e-switch with intuitive controls: a single click powers it on/off, a long press cycles through brightness modes, double-click activates Turbo, and triple-click triggers Strobe. A built-in battery indicator (green, red, flashing red) lets you monitor power levels at a glance. The six output modes—Moon (3 lumens), Low (100 lumens), Medium (350 lumens), High (800 lumens), Turbo (1,800 lumens), and Strobe—give you flexibility for any situation, from discreet night navigation to emergency signaling.

Charging is fast and convenient via the integrated USB-C port. The included 3000mAh 18650 battery charges fully in about 60 minutes using a 5V/2A power source (cable included, charger not). The SC18 also supports reverse polarity protection and low voltage cutoff, safeguarding both the device and battery. For extended use, the advanced Temperature Regulation (ATR) system automatically reduces output if the flashlight overheats, particularly during prolonged Turbo use, helping maintain performance and longevity.

Built for real-world conditions, the SC18 is IPX8 rated—fully waterproof up to 2 meters for 30 minutes—making it suitable for use in rain, snow, or accidental submersion. It’s also impact-resistant, ensuring reliability in tough environments. The included accessories—pocket clip, lanyard, and two spare O-rings—add to its versatility, while the tail-stand function allows for hands-free operation (note: the lanyard may interfere when standing).

While some independent tests suggest the actual output may reach 66–75% of the advertised 1,800 lumens under real-world conditions, this still translates to a highly effective and bright light for its size. The heat generated during Turbo mode is noticeable, but the ATR system prevents damage by managing thermal load. For users prioritising portability, durability, and strong performance, the SC18 offers excellent value—delivering professional-grade lighting in a compact, everyday-ready package.
