Note(s) and/or Footnote(s):

1. The white LED irradiance is supplied by a warm white light-emitting diode with a nominal color temperature of 2700K.

2. The 465 nm input irradiance is supplied by an InGaN light-emitting diode with the following typical characteristics: dominant

wavelength λD = 465 nm, spectral halfwidth Δλ½ = 22 nm.

3. The 525 nm input irradiance is supplied by an InGaN light-emitting diode with the following typical characteristics: dominant

wavelength λD = 525 nm, spectral halfwidth Δλ½ = 35 nm.

4. The 615 nm input irradiance is supplied by an AlInGaP light-emitting diode with the following typical characteristics: dominant

wavelength λD = 615 nm, spectral halfwidth Δλ½ = 15 nm.
