Convoy M21B XHP70.3 Hi 21700 Torch

The Convoy M21B torch is engineered for serious outdoor users who demand high performance, reliability, and durability in a compact form. Designed for those who venture into remote areas, whether on multi-day hikes, night-time expeditions, or emergency scenarios, this torch delivers professional-grade lighting in a user-friendly package.

At the heart of the M21B is the Cree XHP70.3 HI quad-die domeless LED—a third-generation emitter known for its exceptional efficiency and minimal colour shift. Unlike older LEDs that change hue as output increases, the XHP70.3 maintains a consistent, cool white beam (6500K) even at full brightness, ensuring accurate visibility and reducing eye strain during prolonged use. With a maximum output of 2,000 lumens, the M21B cuts through darkness with clarity, making it ideal for long-range spotting, navigation, or illuminating large terrain.

The beam profile is meticulously crafted using a light orange peel reflector, which creates a smooth, throw-focused beam with a well-defined hotspot and controlled spill. This design prevents hotspots from being too narrow or uneven, providing balanced illumination for both distance and surrounding visibility. The result is a beam that reaches over 500 meters—ideal for identifying distant objects, navigating trails, or signalling in emergencies.

Powering the M21B is a single 21700 lithium battery, a high-capacity, high-drain option that supports extended runtime and rapid discharge without performance loss. The 6V 5A boost driver regulates current precisely, maintaining stable output across all modes and preventing flickering or dimming as the battery depletes.

The interface is intuitive and accessible. A single tail switch controls a full 12-group mode set, including multiple brightness levels, strobe, and battery check. Mode memory remembers your last setting, and the torch includes safety features like reverse polarity protection and thermal throttling—automatically reducing output if overheating is detected. A low-voltage warning alerts users before power drops too low, helping avoid sudden shutdowns.

Weighing just 145g without the battery, the M21B is ultra-portable. It fits easily in a pocket or backpack. The tailstand function allows it to stand upright on flat surfaces, useful for campsite lighting, gear checks, or emergency situations where hands are needed elsewhere.
