Disclamair: This flashlight was provided by www.flashlightbrand.com for free. I’ll keep my review unbiased as always.
Introduction.
I never heard www.flashlightbrand.com before so I was curious I cannot say anything good or bad about them since I never bought anything from them but the light came in perfect condition 21 days later. I had 5 months delay during the pandemic for other orders. I hope that this is an indication of shipping is going back to normal.
As for Convoy and the owner Simon this brand needs no introduction, they mostly delivers flashlight with good value, reasonable quality and DIY friendly and also provides more exotic LEDs.

Nichia 219 or 519 is awesome XPL version is also available for less heat.
Good machining, no blemish, nicks, no sharp edges.
Nice color rendering thanks to Nichia 519a.
Nicer to hold due to larger diameter.
Anodized thread(smooth) mechanical lock out is possible.
Square thread.
Relatively cheap for quad emitters light.
Cons:
Gets really hot really fast on High just like Nichia 219. You should get the XPL isntead as it is much cooler but not as nice tint wise. Choose your poison.
Heavy, though not as heavy as 26650, but still weigh down your pocket. You-always-knows-it-is-in-your pocket that kind of feeling
No build it charging.
Neutral:
I wish that it came with 4 different types of optics in the box lol as I found the 60 degree bead optics is to floody.
No clip is provided, probably a good idea?

Your typical convoy flashlight white box.
How it handle in my hand, 21700 flashlight is my opinion a nicer one to hold for longer time.
60 Degree optic with bead. I found this bead optic version cleans up the beam really nicely (sacrificing throw) there is no visible artifacts from 4 emitters but 60 degree just feels like a wall of light no hotspot probably a flat 60 degree or 30 degree flat is more useful.
Head is not glued. the bezel is easy to unscrew without tools.
Lens assembly, notice the fingerprint? it is not mine. The glass is AR coated.
The driver side. There is a 3 pin contact presumably for programming. Notice the rainbow colored spring? the spring was subjected to high heat and not longer able to maintain its shape I am not sure it is like this from the factory or it was mainly my fault? most likely the former since heat like that can only being produced by short circuit. The spring stays crushed and wont return to its uncompressed form. I had problems turning the light on and only to find out that the battery was moving back and forth inside the tube.
the optics
The tail spring also subjected to high heat and cant restored to its uncompressed form so I had to change to a new spring. Since this is the only one I have lying around and it is really long I had to add spring bypass to keep the resistance to minimum. Yeah i know it is too long i will probably get a better and shorter spring later.
The spring bypass with 26AWG silicon wire.
Tail assembly.
Square anodized thread at the tail, smooth and well oiled from factory. Also mechanical lockout is possible.
Tail Stand yay.
Beamshots.
Notes:
Convoy S21D 5000K Nichia 519a vs Astrolux S41 Nichia 219b 5000K
The Astrolux S41D is more focus as you can see in the Beamshots. The comparison is meant to compare tint not brightness.
I found the 519a to be more yellowish compared to the pure white in 219b. I think i still prefers 219b.
4x Nichia 219b 5000k (Astrolux s41)
4x Nichia 519b 5000k

Well you can probably see the trend by now.
Nichia 519a
Conclusion:
I think I have been spoiled by Anduril flashlights and its ramping UI. Going back to a simpler biscotti driver seems to be inconvenient. I found this to be the main problem after using it for 1 week. You can program it to memorized last mode or start at low but not both. The flashlight itself have no problem, it probably wont be become my EDC, that title is still belong to my FW3A with SST-20 mainly because of the size, the weight and especially the UI.
