Review: Manker MK34, 12 XP-G3, 3x18650 Floodlight

Got my 219B MK34 today. Button top Samsung 30Qs from nkon do fit, but barely. I really have to screw the head in with force. No damage to the buttons or batteries though.

Review later, but I quickly measured:
CRI Ra: 92
R9: 73
CQS Qa: 91
Ra,2012: 92
GAI and Ra: 87
TM-30 Rf: 88
TM-30 Rg: 96
TM-30 Rf,skin: 91
Duv: 0.0041 (distance from black body radiator)

My sample of Astrolux S41 doesn’t have a green tint (but it’s not perfect rosy either) and its Duv is 0.0041. For reference, the Olight R50 that has a green tint has a Duv of 0.011. From my quick observation of the new metric I consider everything above 0.01 bad. A rosy tint of Lumintop Tool Cu (219B) has a negative Duv of –0.0008. This is almost perfectly on top of the black body radiator line.

These measurements might change when I test the light in a more controlled environment.
