Convoy 3x21D

Pros

• Exceptional value for the performance, often cited as the best thrower for the money.
• High lumen output and massive throw distance thanks to the SBT90.2 emitter.
• Excellent battery capacity and runtime provided by three 21700 cells.
• Features an efficient 25A buck driver and convenient onboard charging.

Cons

• Bulky and heavy form factor that is entirely unsuitable for pocket carry.
• Poor factory weather sealing; users suggest DIY modifications like epoxy for all-weather reliability.
• The user interface (UI) is considered sub-par or basic compared to enthusiast standards.
• Limited light quality with low CRI and a fixed cool white (5700K) color temperature.

Caveats

• The beam is extremely focused, which can make it difficult to use effectively at close ranges (under 150 yards).
• Achieving very long runtimes (10+ hours) requires staying in lower output modes (e.g., 10%).
• Users note that the high output can easily disturb neighbors if used in residential areas.

Best for

• Long-range spotting of animals or intruders at tree lines.
• Search and rescue or field work where maximum throw and battery life are prioritized over portability.
• Flashlight enthusiasts looking for a high-performance SBT90.2 light on a budget.

Avoid if

• You need a light for everyday pocket carry.
• You require high color rendering (CRI) or a warm light tint.
• You need a light with guaranteed IPX8 water resistance out of the box.
