↑ This - I truly feel at some level led "grow light" companies are intentionally dooping people so they can roll out spectrum one step at a time and keep selling fixtures to the same customers over and over.
The technology is there, yes we see goniophotometers being used but the tech is also there to PROPERLY develop a combination of diodes that gives a true FULL spectrum including Fr/Ir, some UV end nm's, plus a proper spectral blending at distance from fixture.
Hello....Hellooooo....... Where are you led manufacturers that are actually putting in the work?
I think that diy market grow light companies are growing and evolving. They base their product on the call by customers. What they use in product is dictated by what diode manufacturers make available, and what the customers pocket can take.
So whilst companies in the diy/home grow market appear to roll out spectrum, its simply a case of them responding to the call from the customer base, and whatever diode is the latest and most "efficient".
And the customer base is applying spectrum choice based on a mish-mash of cherry- picked data from incomplete scientific papers, and results from online forum influencers. High CRI is the apparent king.
Who is going to produce the one-size-fits-all perfect spectrum? Because cultivar, environment and grower method and application vary.
It would have to be a multi-channel adjustable lamp. That implies complexity.
I would argue that experimenters in this forum who are trying, are still learning what small tuning adjustments have what particular influence.
And when to appropriately apply them. Its still evolving. Open source development is good.
So when you say, "Where are you led manufacturers that are actually putting in the work?"
I would say, look to HLG. Maybe they will develop and give you what you want, once they got their hemp facility up and running.
