5.4 LED colors (ID = 3)
The spectral characteristics shown below are taken from the OSRAM datasheets with friendly
authorization of OSRAM.
The charts represent the characteristics of a single LED. In each Corona II module, two
balanced LED lines are connected in parallel to one external LED-channel. Therefore, the I
F
values must be doubled to describe the behavior of a Corona II module.
