Convoy M21F SFT40 21700 Torch

The Convoy M21F torch is engineered for users who demand top-tier performance without compromising on portability. The Luminus SFT40 LED, known for its efficiency and throw capability, is paired with a precision-machined smooth aluminum reflector. This combination creates a beam that not only reaches over 700 meters but maintains a tight, focused hotspot—perfect for identifying distant landmarks, navigating dark trails, or conducting search and rescue operations.

The torch’s body is constructed from high-grade aluminum alloy, finished with a Type III hard-anodised coating that resists scratches and wear. The stainless steel bezel adds structural reinforcement and protects the lens from impact. The green-coated, anti-reflective (AR) lens ensures maximum light transmission while reducing surface glare, delivering a clear, distortion-free beam.

User experience is prioritised with a side-mounted e-switch that supports a full range of intuitive controls. A single tap cycles through four main modes—0.1%, 3%, 30%, and 100%—while pressing and holding enables smooth ramping between brightness levels. The inclusion of moonlight mode (0.2%) allows for low-impact lighting during night-time camping or wildlife observation, preserving night vision. Turbo mode delivers the full 2,000–2,500 lumens for emergency or high-intensity needs, while strobe is accessible via double or triple taps for signaling.

Charging is simple and convenient with a built-in USB-C port. It supports 5V/2A input, enabling a full charge in under two hours without removing the battery. This feature enhances usability for daily carry (EDC) and extended trips where access to power may be limited.

Safety is built into the design. The torch includes low-voltage warning to alert users before power loss, reverse polarity protection to safeguard against incorrect battery installation, and thermal regulation that automatically reduces current if the body exceeds 55°C. This prevents overheating during prolonged use, ensuring consistent performance and longevity.

The M21F is compact and lightweight, measuring 143.8mm in length with a head diameter of 40mm. The balanced design and ergonomic shape make it comfortable to hold for extended periods.
