When I've finished installing the new module in my projector, I'll do a side-by-side comparison of the new green against a Kvant red (array of 638nm) and a Kvant blue (Single Nichia 445 nm, from when they cost loadsa money, before people started harvesting video projectors...). One thing I can say - compared with my Viasho DPSS green 1W that's just come out of the projector, the new diode green is significantly brighter.
