Maukka has a few beamshots and testing results posted for the LH351D 5000k and 4000k.
It may not be the same bins as what Sofirn uses though and the bin makes a huge differnce.
Without knowng the bins, your playing the bin lottery just like with any other led.
Contactcr also done some good testing using the LH351D with some of them in the same cct but different bins.
