The Convoy M21J SBT90.2 21700 Long Range Flashlight is a high-performance lighting tool designed for users who demand the best in terms of brightness, durability, and range. Built from durable aluminum alloy, this flashlight incorporates advanced features to provide reliable and powerful illumination for a variety of applications. Here, we delve into the detailed aspects of the Convoy M21J, highlighting its key features, technical specifications, and practical uses.
The Convoy M21J is constructed from high-quality aluminum alloy, ensuring a robust and durable build that can withstand harsh conditions and rough handling. This material is known for its excellent strength-to-weight ratio, making the flashlight both sturdy and lightweight.
The flashlight features a sleek and ergonomic design, with a head diameter of 55mm, a battery tube diameter of 28mm, and a total length of 223mm. Despite its powerful capabilities, it weighs only 274g, making it easy to carry and handle. The ability to tail stand adds to its versatility, allowing it to be used as a hands-free light source when needed.
At the heart of the Convoy M21J is the SBT90.2 LED, renowned for its high brightness and efficiency. This LED produces a maximum luminous flux of 5000 lumens, providing intense and powerful illumination. The theoretical output value indicates the potential brightness, though the actual output may be slightly lower due to real-world conditions.
The flashlight is equipped with a 50mm 3-degree TIR lens, designed to focus the light into a tight beam for long-range applications. This lens type ensures that the light can reach distant objects, making it ideal for search and rescue operations, outdoor exploration, and other activities where long-range visibility is crucial.
The Convoy M21J includes a low voltage warning feature that automatically powers off the flashlight when the battery voltage drops too low. This protects the batteries from over-discharge and ensures that users are aware when it is time to recharge or replace the batteries.
This feature prevents damage to the flashlight's circuitry caused by incorrect battery installation. If the batteries are inserted backwards, the flashlight will not power on, safeguarding the internal components and extending the lifespan of the device.
The M21J is equipped with an intelligent high temperature protection system. When the temperature of the drive board reaches 55 degrees Celsius, the current gradually decreases to prevent overheating. This reduction in brightness is imperceptible to the naked eye, ensuring consistent performance without causing a noticeable change in light output.
The Convoy M21J is designed with user convenience in mind. It features a side button for switching modes and a tail button for turning the flashlight on and off. The forward switch in the tail allows for momentary or constant-on operation, providing flexibility in how the light is used.
The flashlight offers a mode memory function, which remembers the last used mode and returns to it when the flashlight is turned on again. This feature is particularly useful for users who prefer a specific brightness level for their tasks.
The Convoy M21J requires two 21700 batteries, capable of handling a current of up to 10A. This power source provides ample energy for the flashlight's high output and ensures long runtimes. The flashlight does not include a built-in charging port, so users will need an external charger to recharge the batteries.
With an output current of 20.5A, the M21J ensures that the LED operates at peak performance, delivering consistent and powerful illumination. The choice of 21700 batteries provides a good balance between capacity and size, making the flashlight both powerful and portable.
The Convoy M21J is suitable for a wide range of applications, thanks to its powerful performance and versatile features:
The flashlight's long-range beam and high brightness make it an excellent tool for search and rescue operations. It can illuminate distant objects and cover large areas, helping rescuers locate people or items in low-light conditions.
For hikers, campers, and outdoor enthusiasts, the M21J provides reliable illumination for navigating trails, setting up campsites, and exploring the wilderness. Its durable construction ensures it can withstand the rigors of outdoor use.
The high brightness and strobe mode make the flashlight useful for security personnel and law enforcement officers. It can be used to disorient potential threats, illuminate dark areas, and signal for assistance.
In emergency scenarios such as power outages or natural disasters, the M21J offers a dependable light source. Its low voltage warning and high temperature protection features ensure it operates safely and effectively.
The Convoy M21J SBT90.2 21700 Long Range Flashlight is a top-tier lighting tool that combines advanced technology, robust construction, and user-friendly features. Its high-performance LED, intelligent protection systems, and versatile modes make it suitable for a wide range of applications, from professional use to everyday tasks.
The flashlight's durable aluminum alloy body, combined with its intelligent features such as low voltage warning, reverse polarity protection, and high temperature control, ensures reliable performance in various conditions.
