What, that the emitters can be custom picked? Perhaps, I'm just quoting their website. Could be XPEs or something. There are pics of the front panel on the website but you can't see much. I doubt there would be a pic of a custom array anyway.

I'm not sure though, why show off a lamp and not give any specifics including a name brand?

Yes . They told me that some led grow light with CREE OSRAM LED Chip are expensive for some growers . That's why they use some cheap led chips like other manufacturers . So far all good .
 
Their website shows a few CREE reels with bin numbers

XPE 3800K R2 bin @700mA (assuming typical numbers and Tj 50C)

The royal blue D3 bin, typical numbers Tj 50C

So 26% for the whites, 42% for the blues and ~32% for the reds, assuming they are at Tj 50C which may not be the case because the thermal path has to pass through a warped aluminum plate. Would be interesting to check the temp droop.

Just to let you know guys, fake XP-Es are known to be produced. I certainly wouldn't buy this panel.
