Why no red COB's?

It's just that, sourcing a PPFD meter is not like shopping on amazon.
Each PPDF has their own measuring specification, some do not measure as low as 450nm, and some do not go as high as 660nm.
Some don't come with spectrum filters, some don't come with attachable ppfd readers and must be hand held .. etc.

So, we custom ordered a lab grade ppfd meter which takes time to manufacture and build. So I do apologize for not shopping on Amazon Prime.

So you can build a red chip better than cree,but you dont have the wherewithal to even have a ppfd meter? Really? Peace bro im out.lol

Sounds good. You will be using the Duet? The blue channels are 3.34 umol/J making the unit overall 1.84 umol/J according to the datasheet. Will you be running them at nominal current? I do appreciate the availability of datasheets and the opportunity to test blurple with known parameters. If blurple is worthy then 1.84 umol/J should pull decent numbers, though the efficiency on those reds isn't exactly something I would brag about.
