Just a small correction :
Prometheus FourSevens /4Sevens Mini Turbo MKIII 
Although it is now under Jason Huiās charge, they still brand it as 4Sevens. Actually, they are releasing now some new lights under the brand
Add:
MecArmy PS16 (1000 lumens)
Olight S1R Baton II (1000 lumens)
Butā¦this Acebeam TK16 is something gorgeous :heart_eyes:
I love mine!
Didnāt list the PS16 because that is an 18350 light that works with 16340 so itās much larger in size. Once it gets up to 18350, there are a ton of options including the D4 shorty, Thrunite T1, Tiara Pro, etc. The Olight S1R baton is also a good one. I have it also just donāt like the CW tint and pressed bezel is too hard to remove.
I also really like my TK16 Oslon White Flat version although I got the black anodized aluminum instead of the copper. Which version did you get?
Oops, youāre right :person_facepalming: The PS16 is 18350 oriented yes 
Sorry!
About the TK16, I also got the Aluminum version
And I am quite impressed with it. Despite the artifacts on the beam, I like it a lot! And the turbo on POWER mode? Insane 
I just tested the TK16 Osram version with these three cells. The new Vapcell 800mah is clearly the king of 16340.
Vapcell 800mah
Output: 1,184 lumens
Tested capacity: 781, 782, 791, 757 mah
Acebeam 550mah
Outpu: 1,190 lumens
Tested capacity: 617 mah
Efest 700mah Red wrapper
Output: 1,112 lumens
Tested capacity: 685 mah
Here are measurements I took of the different Acebeam TK series flashlights using the Texas Ace Lumen Tube calibrated with Maukka lights measured at 2 seconds. I love this series but not so much the emitter options. The Osram is actually my favorite tint in this series even though I'm not a CW fan because the negative DUV in the Osram makes it look pure white. I just wish they offer some below the BBL (negative DUV) NW tint in the future.

Good work SKV89. Thanks for sharing more data with us.
One of your 219C lights looks like it has fairly good tint. The other one typical for 219Cās.
Wow! That XP-G3 light either must have had a measurement error, or it must look downright purple.
