The Convoy L21B Long-range Hunting Flashlight is a powerful and highly customizable illumination tool designed for outdoor enthusiasts, hunters, and tactical users who require reliability and performance in challenging environments. Constructed from durable aluminum alloy, the flashlight combines a sleek, robust exterior with advanced functionality, making it suitable for demanding field use. It is equipped with high-performance GETIAN LEDs available in blue, green, and red variations, allowing users to adapt the light to specific tasks such as tracking, signaling, or preserving night vision. Each color operates within a precise wavelength range—blue between 450 and 460 nanometers, and green between 520 and 530 nanometers—ensuring optimal visibility and effectiveness in different scenarios. The smooth reflector and AR-coated glass lens work together to maximize beam intensity and distance, delivering a concentrated throw ideal for long-range spotting.
At the core of its performance lies a powerful driver capable of a maximum 8A output, supporting twelve programmable mode groups. This advanced configuration system offers users a unique level of control rarely found in similar flashlights. Activation and mode switching are intuitive: a full click of the rear tail switch turns the flashlight on or off, while a light tap cycles through available brightness levels. Entering the configuration mode involves tapping the switch twenty times while the light is on, triggering a series of coded flashes that indicate specific options. In Option 1, users can select from twelve sub-groups of lighting patterns, which include various combinations of brightness levels, strobe, SOS, biking, and battery-check modes. Each sub-group is identified by a distinct number of flashes, from one to twelve, providing a surprisingly efficient method for navigating settings without a digital interface. Once inside a sub-option, tapping the switch confirms the desired group, and if no action is taken, the light progresses to the next configuration step. Option 2 governs the mode memory function, enabling or disabling the flashlight's ability to recall the last used mode upon the next activation.
The flashlight supports tail-standing for hands-free use and features reverse polarity protection and low voltage warning, enhancing safety during operation. The battery-check function is especially useful in the field, as it allows users to assess remaining battery voltage through a simple series of flashes: one flash indicates a voltage below 2.95V, two flashes signify 2.95 to 3.25V, three flashes represent 3.25 to 3.55V, four flashes correspond to 3.55 to 3.85V, and five flashes show a voltage above 3.85V. These indicators ensure users are always aware of battery status, reducing the risk of unexpected shutdowns.
The Convoy L21B requires a single 21700 lithium battery, which is not included in the package. This battery type offers a higher energy density and longer runtime compared to standard 18650 cells, making it a suitable choice for a high-powered flashlight of this class. With a length of 170.5 millimeters, a head diameter of 62.6 millimeters, and a body diameter of 26.1 millimeters, the flashlight is ergonomically balanced for handheld use while maintaining a compact enough profile for easy storage in a pack or pocket. Its net weight of 212 grams, or 247 grams when packaged, reflects its solid construction without being overly heavy, striking a balance between rugged durability and portability.
Every design aspect of the Convoy L21B reflects an emphasis on functionality, resilience, and user control. The combination of a tough exterior, precise optical engineering, and deeply customizable light outputs make it an ideal choice for those who need dependable illumination in outdoor, tactical, or emergency situations. Whether scanning a distant trail, signaling teammates, or performing a battery check in the dark, the L21B delivers consistent performance with thoughtful features that enhance both safety and usability. This flashlight is not just a lighting tool but a versatile companion that adapts to your needs through intuitive controls and a robust, efficient design.
