I do think the brain is very good at interpreting incomplete visual data, and with a single light source, it will adjust its white balance. I dont think it adjusts the CRI of the LED though…
as to why an old Hippy into natural foods, and organic farming would be interested in High CRI… I think it is me trying to use the most Organic Light, given the option…
In the above photo, the wood of the table is not actually green. It is the lack of R9 in the Low CRI LED, that omits the red spectrum content of the wood.
a more subtle example:
I know the flower on the left is a Rose, but given the choice, I get more excited looking at the one on the right (it is a Higher Fidelity, fuller spectrum image):
so true!
which is why I think it is important to note ambient adaptation, when making an observation about the color of an LED output.
High CRI lights are great, and I love the ones I’ve got. But the main reason I like them is they have the CCT I like and the tint I prefer. The fact they are high CRI is the icing on a very sweet cake.
The reason I recommend High CRI, is because I like the superior color rendering, tint, and CCT.
Lets use a real world example. Someone asks, which AAA Tool should I get, the CW that is brighter, or the High CRI, that has less lumens.
My first answer is always, get the High CRI.
I dont necessarily go into the details that the High CRI being offered is a Neutral White Nichia instead of a Cool White Cree.
and I dont necessarily go into the details about the CW having green tint, while the NW has pink tint… all of those CCT and DUV factors are included automatically in the recommendation to choose the Nichia.
I do post photos showing the difference in tint, and Im honest about the difference in lumens…
some people prioritize lumens over CRI, Tint, and Color temperature…
it is their choice
if they ask which Emissar D4 LED to choose, then the answer is more complex, because the LED option is more than just Nichia vs Cree. I still say get the High CRI, but now the buyer must also decide the CCT and Tint they prefer.
the answer is more or less detailed depending on the actual real world choices available… for a given model of light.
