3 LEDs = Chain of component arrows with cyl radius = 0.03. Stimulus vector = [3.338, 0.3331, 2.178]
Correlated color temperature = 5497.8.
Indices of the LEDs = [86, 56, 28] and their names are:
    HLMP-EH25-SVOOO RED-ORANGE,
    HLMP-CM15-S0000, and
    Roitchner Lasertechnik LED 450-01U.
The peaks occur at [628, 522, 446] nm
Reference light = Blackbody 5500 = Chain of arrows with cyl radius = 0.02 . Stimulus vector = [3.338, 0.3331, 2.178]
Fattest arrows show the orthonormal components:
Stimulus components in orthonormal system = 3 arrows of radius = 0.04, gray, red, and blue. Stimulus vector = [3.338, 0.3331, 2.178].
The large spheres are the blackbody locus at a fixed radius from origin.
Starting with the reddest, the temperatures are: [2000, 3000, 4000, 5000, 7000, 1e+004, 2e+004, 1e+005]
