Interesting would be, if you would test different CRi values (higher than 95) on these powerful LED lamps at same settings you did here so very nicely in your studio . .. so it would be consistent all the time. Yours here have a very low CRI color values it seems. Although LED's are seemingly brighter, the tint they have, are impossible to remove in Film editing software .

let me explain :

First: Cri values are technically "NOT" applicable to LED lights, (contrary to common believe), Cri value is solely applicable to Fluorescent Lights for which it was invented, and additionally , such a Cri Number is "NOT" Spectroradiometer measured , but its a mere, rough and only subjective (human person) measurement, guessed by the Human Eye of a Person, (what a farce, right?).
It still would be interesting to see how they perform in your tests here, if you were to test/buy LED lights with a high Cri value of 95 and above. (do they exist yet?)

this video, which is part of a series of videos about LED in Film and Photography , explains it more technically :

There are newer color values measurements Units around then the old Cri , but sadly not many are talking about this norms yet, and consequently the masses are not using this newer color standards yet neither.

Spectroradiometer ( https://en.wikipedia.org/wiki/Spectroradiometer ) : thats a machine which measures not only the Kelvin values as well as the brightness, but more specifically measures the missing colors as well, in contrast to a better known Photospectrometer, wrongly used here for that matter, and usually only used to calibrate monitors and printing machines, which most think so very wrongly , is the measuring hardware to be using here on LED's.
The results with your Color-meter here miss the point of LED problems, which are those muddy colors, originating from missing in-between colors.
Only a Spectroradiometer ( https://en.wikipedia.org/wiki/Spectroradiometer ) can measure these color amounts in each specific wavelengths.

It would be amazing if you would redo these tests scientifically correct, may be with the help of a Physics Professor from NYU, for example?

Again: why this is so incredibly interesting is, because LED almost always misses colors in-between the colors that a tungsten light would have no problem to create, and the editing & color grading in LED lit video/filmclips, with any of these film softwares out there, is almost impossible, for these clips are missing those colors in-betweens in LED lights, which ends up only creating a muddy color tint , usually not fixable in postproduction yet . A simple more understandable example is this: Imagine you have only a red bulb a blue bulb and a yellow bulb in that studio, now turn these on, and film a persons face. the colors would be horrible, for they are missing in-between colors. There is no software in the world (yet) that can generate in-between colors which would Fix those missing in-between colors that LED lights create.

400$ for software and hardware ? Hmmmmm.... i own a Photo spectrometer from GRETAG (...sadly now its called in the USA X-Rite, in Switzerland , where GRETAG is from, GRETAG still exists ,...BTW!!....) i paid up around 5'000 USA dollars. it worked well, ...actually very very well. This here seems to be a joke,.... consider the girls on this picture, .... and their outfit.... unless this is an April 1st joke.... i don't know what is real here,.... but one thing is certain: I WOULD NEVER INVEST A CENT INTO THIS PACKAGE HERE.... X-RITE has definitely gone down the PORN avenue here... Akos SImon
