Convoy M21H
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Convoy M21H is a budget-friendly 21700 flashlight highly regarded for its versatility and value. It is frequently recommended as a low-cost alternative to premium lights like the Acebeam L35, primarily due to its swappable TIR (Total Internal Reflection) optics and extensive emitter options. While praised for its performance-to-price ratio and integrated USB-C charging, it faces criticism for a clunky user interface and lack of advanced driver options.
Pros
- Excellent value, often cited as a 'poor man's Acebeam L35' for around $30-$40.
- Highly customizable with multiple TIR lens options (3, 8, and 12 degrees) to adjust beam profile.
- Wide variety of available emitters including SFT40, SFT70, XHP70.3, and GT-FC40.
- Integrated USB-C charging for convenience.
- Capable of significant throw (up to 600m) depending on the LED and optic configuration.
Cons
- Polarizing user interface (UI) with issues like memorized turbo and a relatively high 'moonlight' mode.
- Inability to cycle from moonlight directly into main modes, which can lead to accidental blinding.
- Lack of high-current driver options (e.g., no 6V10A driver) for specific high-power builds.
- Minor quality control quirks such as misaligned stickers or green-tinted LED bins.
Caveats
- Users recommend purchasing a 'butterfly gasket' separately to ensure the cleanest beam profile.
- Waterproof ratings are generally considered lower than those of premium competitors.
- The stock UI is often the primary dealbreaker for enthusiasts accustomed to Anduril 2.
Best for
- Budget-conscious flashlight enthusiasts who enjoy modding or swapping optics.
- Users looking for a versatile 21700 light with built-in charging.
- Anyone seeking a high-performance beam similar to the Acebeam L35 at a fraction of the cost.
Avoid if
- You require a sophisticated UI like Anduril 2.
- You need a true sub-lumen moonlight mode for use in total darkness.
- You require professional-grade waterproofing for extreme environments.

I rock the M21H with a SFT40 3000K and I love it.
I also recommend taking a look on the Convoy M21H with SFT40 or SFT70, you can choose 5000K and 3000K High CRI on both versions and also 4000K High CRI on the SFT70.
There are also cheaper options like the Convoy M21H. I'm not sure whether you're into good light quality or have a preferred CCT, but it comes with a huge variety of emitters and with its stock 8° TIR optic it gives a really versatile beam profile, slightly more uniform than what you get with the E75's quad reflector
I've got the sft40 3000k in an M21H. Lights for all occasions!
The M21H is a pretty awesome flashlight, I liked it even more than the M21K. The SFT70 4000K 90 CRI has an amazing neutral tint, it's light is pretty powerful even with the neutral CCT and high CRI; the MAO anodizing is beautiful, but it's a little easy to scratch it; the 6V 5A driver is really poweful (although a 6V 8A would be pretty welcome); the 8° TIR is one of the best I've used, it makes the beam super clean without any artifacts at all.

Convoy m21h with a Xhp 70.2 LED you will need to get a battery from Conway it's sold on the same page this one also has on board charging
I think in the M21H it's a much better light. Much more usable. ... It's worth getting the 12° as well, to see which you prefer considering the price Simon sells them at.
Parent context: Do you find the spill to be more usable with the M21H and 8deg TIR? Reply: A bit. Mostly just a lot smoother. I also like the 24°. If I remember right, there was noticeably more spill with that and the 36.
I love this led in the M21H w/8° TIR. You lose a bit of performance, but the beam is really nice.
