| 6. A method of illuminating a subject, comprising:
generating a variable amount of light of a first wavelength and a variable amount of light of a second wavelength, wherein
the second wavelength is different from the first wavelength;
optically combining the light of the first wavelength with the light of the second wavelength;
illuminating the subject with the combined light;
adjusting the amount of the light of the first wavelength or the amount of the light of the second wavelength, to achieve
a color characteristic of a desired illumination of the subject with the combined light;
recording the amount of the light of the first wavelength and the amount of the light of the second wavelength contained in
the combined light used to achieve the desired illumination of the subject;
setting a lighting system to generate the recorded amount of the light of the first wavelength and to generate the recorded
amount of the light of the second wavelength;
operating the lighting system to generate the set recorded amounts of light of the first and second wavelengths;
optically combining the light of the first and second wavelengths generated by the lighting system to produce a combined light
output corresponding to the desired illumination; and
irradiating the subject or a similar subject with the combined light output from the lighting system, to achieve the desired
illumination of the subject using the lighting system,
wherein the step of operating the lighting system to generate the set recorded amounts of light of the first and second wavelengths
includes activating at least one initially inactive source of light of one of the wavelengths.
