Convoy L21b

Pros

• Exceptional throw distance, often compared favorably to much more expensive LEP flashlights
• Excellent value-to-performance ratio, frequently cited as an 'A+ tier' budget option
• Lightweight design makes it suitable for weapon-mounting or long carries
• Available with a variety of high-performance emitters like the SFT40 and SBT90.2

Cons

• Reduced mass can make the light feel 'cheaper' or less robust compared to the heavier L21A
• Lower thermal mass means it may heat up quickly or have less heat-sinking capability than bulkier alternatives
• The beam can be 'too throwy' (too narrow) for general-purpose use

Caveats

• Specifically designed with less mass to be lighter, which is a deliberate tradeoff against durability and heat management
• Users often need to purchase batteries and chargers separately as they are not always bundled

Best for

• Long-distance spotting and search tasks
• Budget-conscious enthusiasts wanting maximum beam distance
• Users looking for a lightweight, large-head thrower

Avoid if

• You prefer a flashlight with a heavy, 'premium' hand-feel
• You need a versatile beam for close-up or indoor work
• You require high sustained output where thermal mass is critical
