The warm Yinding has been tested, and the performance was disappointing. Not only does the output underperform the XPL-HI, but so does the intensity! I think the XPL-HI is a much better bet.

Also, the die of the Yinding emitter is often off-center from the square footprint, which does not play nice with a reflector.
