It's a very interesting LED, but unbelieveably inefficient! Even the CRI rating doesn't justify this (other manufacturers offer similar LEDs with higher efficiency). It's also way too expensive. Other high-cri COB LEDs cost about one tenth.

A rough calculation of the luminance (assuming it's evenly distributed) shows that it is very low, 25cd/mm^2. So basically this LED will not throw, even with a big reflector.
