Sofirn SK40 21700 Torch

The Sofirn SK40 is a high-performance flashlight engineered for demanding outdoor and emergency scenarios. Designed with precision and durability in mind, it delivers exceptional brightness and long-range illumination, making it ideal for search and rescue operations, night hiking and camping. At the heart of the SK40 is a premium SFT70 thrower LED, capable of producing a maximum output of 3200 lumens. This intense beam can project light up to 580 metres, ensuring clear visibility over vast distances—perfect for scanning terrain, identifying objects in the dark, or signalling over long distances.

The dual switch design enhances usability across a wide range of situations. The tail switch offers a quick, tactile click for momentary or constant-on operation, ideal for tactical applications where rapid activation is crucial. The side e-switch complements this with precise mode control, allowing for smooth transitions between brightness levels and functions. With both duty mode and tactical mode, users can tailor the light’s behaviour to their environment—whether it’s a steady beam for reading or a strobe for self-defence and crowd control.

Powered by a single 21700 lithium-ion battery, the SK40 provides extended runtime and reliable performance even in extreme conditions. The flashlight supports USB Type-C charging, offering fast, convenient recharging with any standard cable—no need to remove the battery for charging, saving time and improving usability.

Constructed from high-strength AL6061-T6 aviation-grade aluminium alloy, the SK40 is built to withstand drops, impacts, and harsh weather. Its robust design includes an IP68 waterproof rating, meaning it is dustproof and can be submerged in water up to 2 metres deep for 30 minutes without damage. This makes the SK40 suitable for use in rain, snow, mud, or even accidental submersion—ideal for unpredictable outdoor environments.

The compact size of 146.5mm in length and 40mm in diameter ensures it fits comfortably in a pocket, backpack, or gear pouch. Weighing just 132g without the battery, it adds minimal bulk to your load while delivering powerful performance. The textured, anti-slip surface enhances grip, even in wet or cold conditions, ensuring secure handling during critical moments.
