Flashlight Comparison: Convoy M21F vs. M21H - which is best?

Summary

In this flashlight comparison, the Convoy M21F and M21H are analyzed for their design, beam profiles, and performance. The M21F offers a wide flood beam ideal for general use, while the M21H is built for long-distance throw with a more focused beam. Both models feature USB-C charging, 21700 battery compatibility, and high efficiency, but the M21H excels in throw with a more powerful emitter. The video highlights their differences through beam shots and performance testing, helping viewers choose based on their lighting needs—whether for general lighting or long-range spotting.

Takeaways

• 😀 The Convoy M21F and M21H look similar in design but have distinct differences in performance and beam profiles.
• 😀 The M21F has a more general flood beam with some throw, while the M21H has more focused throw with less spill.
• 😀 The M21F uses an LED that produces a more practical, wider beam with good efficiency, capable of reaching around 4,000+ lumens.
• 😀 The M21H uses the XHP 70.3 high emitter, which offers significantly more throw than the M21F, with a narrower, more concentrated beam.
• 😀 The M21H produces much more throw, which makes it ideal for long-distance spotting.
• 😀 The M21F’s beam is wider and covers more peripheral area, offering a more versatile beam profile suitable for general use.
• 😀 The M21H offers a high level of efficiency despite its intense throw, and the LED doesn’t get excessively hot during use.
• 😀 Both flashlights feature USB-C charging and are compatible with 21,700 cells for power.
• 😀 The M21F has more heat sinking around the head and bezel, while the M21H has less but compensates with a higher throw output.
• 😀 During the beam comparison, the M21F has more spill, which starts about four meters ahead, whereas the M21H’s spill starts much closer at around 30 centimeters from the foot.
• 😀 The M21H offers a more useful beam profile overall, providing more peripheral spill for increased visibility, making it more practical for outdoor or emergency use.

Q & A

What is the main difference between the Convoy M21F and M21H flashlights?

The primary difference between the M21F and M21H lies in their beam profiles. The M21F is designed for a wide flood beam, making it ideal for general use, while the M21H focuses on long-distance throw with a narrower beam profile.

What type of emitter is used in the Convoy M21F, and what effect does it have on the beam?

The M21F uses the CUL PM1 TG emitter, which is a small LED with high surface brightness. It produces a broad, flood-style beam with some spill, providing good general illumination over a wider area.

How does the emitter in the Convoy M21H compare to the M21F's emitter?

The M21H uses the more powerful XHP 70.3 high emitter, which offers a significantly better throw, producing a tighter and more focused beam for long-distance illumination. It also has a more efficient design, with minimal heat buildup.

How do the beam profiles of the M21F and M21H differ in real-world tests?

In real-world beam tests, the M21F produces a wider beam with spill that begins around 4 meters ahead, offering balanced illumination. In contrast, the M21H starts spilling almost immediately and has a much tighter spot, ideal for long-distance use.

Are both flashlights rechargeable, and what battery types do they use?

Yes, both the M21F and M21H feature USB-C charging, and both use 21700 cells, making them compatible with high-capacity rechargeable batteries.

Which flashlight is more efficient, the M21F or M21H?

The M21H is more efficient, with its XHP 70.3 emitter offering better throw and performance without generating as much heat. The M21F, despite being less bright, tends to get hotter.

What is the maximum lumen output of the M21F flashlight?

The M21F can produce over 4,000 lumens, making it quite bright for a flood-oriented flashlight.

Which flashlight would you recommend for general everyday use?

The M21F would be recommended for general everyday use, as its wide flood beam provides practical illumination for a variety of tasks and environments.

What are the advantages of the M21H’s narrow beam profile?

The M21H’s narrow beam profile allows for long-distance throw, making it ideal for spotting objects at a greater range, such as during outdoor activities or search-and-rescue operations.

What are the key considerations when choosing between the M21F and M21H?

When choosing between the M21F and M21H, consider the intended use: If you need a flashlight with a wide, practical beam for general tasks, the M21F is a better choice. If you require a focused, long-range beam for spotting or tactical applications, the M21H is more suitable.
