Seriously fellows, for some reason I am subscribed to this thread so I guess it's time to kick ass.
Do you believe CRI makes little or no difference for you? Seriously?
Aim a cheap whatever colour laser (a score of 0 CRI, I believe) at something and see if you can tell me it allows you to discern colours beyond the vicinity of the emitter frequency well. Busted, doesn't it?
We humans are adapted to the main available light sources in our evolutionary timeline: the sun and fires. These sources are spot on the black body locus with perfectly uniform spectral power distributions. Light sources which deviate from this are going to be noticed, the more the harder.
Now I must promptly say that despite leds are completely synthetic light sources, we've come far enough already but still there's way to go.
Of course I can respect what you believe and each one of you can have her/his own reasons, but when I aim a good high-CRI torch at a chosen target with a good range of vivid colours and next I do the same with a dull emitter equipped equivalent torch the difference can be quite noticeable. All my close friends are “converting” to this high-CRI religion and honestly, with little effort from my side.
Cheers my dears :-)
