Figure 2.

Spectra color composition and spectra curves of the CoeLux^® (blue),the HPS (orange), and the Sun (yellow) light types. Spectra measurements were collected in the range between 380 nm and 780 nm for each light type. To allow the comparison, photon counts measurements were normalized on the luminance of the respective spectrum. In the table, the sum of normalized photon counts was calculated for each color interval and reported in the form of relative intensity ± standard deviation. Spectra curves represent the mean of 8 different measurements (n=8).
