It would be nice to see a spectral plot of the new LED lamp.
I mean the CDI 400Watt Multispectral Constant/Flash Light Engine
After searching more pages mentioning the lamp I still am curious about the continuity of the spectral output.
The analogy to an Epson printer using CMYK(RGB) cartridges escapes me. White is paper white there, the color mixing is subtractive to create color and the hues are preferably spectrally separated to get better color mixing, all CMY channels open gives a muddy grey color so is substituted by black ink for better neutrality and Dmax. In contrast the LEDs suffer of spectral spikes and valleys in their output and one has to add different types together to create a better white emission by additive mixing. And/or use fluorescents for the same effect, by that reducing the economy of the LEDs.
