Nice beast!
But I wonder, as with any very high power LED, about thermal management. That emission is at case temp of 25ºC and Tj=55ºC. For real conditions they must be way higher, very aggressive heatsinking required to avoid it cooks up. The really low thermal resistance case to junction (0.3ºC/W) is achieved by COB on aluminium, with no protection diodes. I would like to see this device exposed to thermal cycling and aging when operating at high currents, good reliability would surprise me. But if it is well priced, for some applications it seems a nice option.
Anyway, running it at lower power, 80-85W at 1,5A gets a typical emission of 9890lm, which is very good at 120lm/W. But both color tint and rendition seems horrible, just suited for security lights, garage lighting and so. Cromaticity is directly well over the planckian locus, with a greenish tint.
The choices of CRI80 have way better color, at the cost of 15-20% less lumen. Adequate for most applications, around 100lm/W (1,5A, Tc 25ºC)
