So I get that a higher CRI value means the led is capable of creating a more uniform and pleasing lighting aesthetic for humans but does it really mean anything to the plant so long as the minimum spectral power needs are met? The CREE literature shows graphs of relative power output at a given frequency for various CRI values but I interpret this as an intensity related to the overall quantity of light generated by that LED. Meaning that although the 93 CRI 3000k leds show more area under the graph at a given frequency it may not actually produce more photons in that region that an 80 or even 70 CRI?
For whatever reason I think the plant can handle a slight variation of color so long as it meets some minimum level. A little extra blue or a little extra red and the light looks blurple to us and is annoying but doesn't have a huge adverse affect as long as we stay away from the extremes.
On ANSI color bins I think my question is at least slightly related to the above thought train but it seems to my uneducated brain that these focus on getting accurate color at the light temperatures that are pleasing to humans and less effort is placed on manufacturing leds optimised to create a photoactive environment. Basically it looks like these might be good option if high CRI values are desired in the 5000-6500k color range? There must be a reason why these are so much less expensive but I wonder if it is that CREE dosen't recognise them as meeting the needs of a specialty market and therefore could "justify" asking a premium price for them??? or are they total crap for plants??
I am new to LEDs and due to a poorly researched purchase have been thrown into this world. So I beg your forgiveness in advance, and appreciate any insights.
