Mixing 2 Tints - am I Making My Own Higher CRI or Not?

Im contemplating purchasing a pair of dedicated zebralights for use on my work helmet: Two H501s strung on the same headband.

Here's my question: Should I mix a cool and a neutral white? Alternately I'd go for two of the neutral lights instead (which look warm to my eye).

Am I making a higher CRI (so to speak) by mixing a cool with a neutral? Is there any real advantage to mixing two tints? If not Ill probably just go for two neutral tints.

I remember the gist of replies to this thread...answer was "maybe a little, but mostly not."

Pretty much. The best you can hope for is a nice balanced white, but not really high CRI.

Sums it up pretty well. I remember I made a reply, but I can't remember the exact contents. For anyone who stumbles on this thread in the future, it was pointing to the datasheets and how there'd still be huge gaps in the spectral distribution of such a combination, most notably around the 475-500 nm area, and then again in the deep/far red section.

Coming across this got me thinking. What if you have a high CRI but too-warm LED that you pair with a cool or neutral low-CRI LED? What I have in mind is Cree's 90 CRI 3000k XP-G. If I paired this with a Cooler LED would I have a better color temp, and still retain a CRI higher than the typical 75 or so?

I've actually tried something like this (H501w with cool hand-held). While it may not technically be high CRI, it most certainly results in more pleasant and useful light. I've found it particularly useful to identify similar wire colors in confined areas (work on boats).

I can't see why not. It'd be an interesting experiment.

I tried this with a quad XPG P60 mixing neutral and warm. A straight neutral produced better color rendition.
