Manker MK34 219B vs. 219C: 219B is brighter!?

This is old, not sure anyone cares anymore, but…

An obvious explanation would be Manker used the 83 CRI R8000 219B and the 90 CRI R9050 219C. Both have same output.

219C: 90+ CRI NVSL219C R9050 D240 4000k CRI92

219B: 83 CRI NVSW219BT-V1 SW5055-5088/D240-260/R8000 not the R9050 219B.

Manker CS rep thought that both the 219B and 219C used in MK34 were 90+ CRI, but said the 219C had a higher CRI than the 219B. Either a) the second part of that sentence is correct and the first incorrect, or else Manker produced some runs with 83 CRI 219B’s and some with 90 CRI 219B’s, hence the conflicting reports.

maukka measured the 219B MK34 ( Review: Manker MK34, 12 XP-G3, 3x18650 Floodlight - #85 by maukka ) to CRI 92.
