Great review!
This week I received my Convoy S21D with Nichia 519A 4500K leds.
I absolutely love this flashlight!

I bought the Convoy S12 with 3x 519A 4000k-4500k.
I'm greatly disappointed with lumen output.
Light seems quite anemic on highest level.
Nothing close to the 2300 lumens that Simon calculated, @8000 mA

That is consistent with the ZeroAir review, which measured the output (with an SST-20 4000k) at only 1300 lumens. Your 519A at 4000k, which is also high-CRI, is probably similar. Seems like the S12 is simply under-driven or over-claimed.
