Re: Document
Abstract: The argument on slide six in is based on a particular spectral chart of LEDs. I am presenting five charts that show an opposite behaviour (smaller bandwidth in the blue and red, wider bandwidth in the green). I therefore claim that this argument is not based on a comprehensive sample of commercially available LEDs.
Purpose: Resolution of CID 29 in

Conclusion
Argument on slide six in document not based on comprehensive choice of commercially available LEDs and thus of elusive validity.
Notice: this is the only argument for the chosen band plan.
Side note: claim two on slide three in document („LEDs are primarily designed for illumination based on color and human eye sensitivity to color.”) is also in conflict with empirical evidence (see contra 1, 2, 4).
