Has anyone noticed that the higher CRI cxb's are available 2 bins higher than the cxa was, as where the 80 cri cxb's are only one bin higher.
There will still be a lacking of output comparatively to it's 80CRI counterpart...but not as drastic as before.
Also the high CRI seem to have passed hps efficiency...which to me has always been the... should I use it, or shouldn't I use it line. But now that they are producing enough light(~42%+/-) to compete with hps...they might be worth incorporating, or even going all they way through...@hyroot.
The one thing that could throw a little wrench in the progress is that they changed the high cri from 90min/95typ(LER=275) to 90min/92typ(LER=?)...so slightly lower cri typical...with could affect the LER, and counter the extra bin in efficiency. But I still think the extra bin should still come out ahead of the cxa even if the LER is slightly higher.
Another thing is that with the higher CRI, I can see higher K temps giving the better/more ideal ratio's of nm's... while also allowing an other additional bin gain to be used. We just need some more SPD charts to really see what the higher cri(even 80cri 4K is unknown to us still...let alone 90cri 4K). 4k 90cri comes in AB..which we know AB kills it as far as enough total light...but this high cri version is doing it efficiently too, like the cxa 3K AB 80cri did.
Or the ultimately could happen...cree could have a 3000k BB on the back burner waiting to add to the sheet like they did with the ABcxa...to make 3 bins per color temp like before...all speculation/optimism/hope on that part though.
But the improvement in the higher CRI category was something worth noting.
