Thanks for the information. I am confused by your choice of wavelengths for the blue and red LEDs. Please explain why you chose the wavelengths shown above. And, if you are using blue LEDs at 472nm, why is this not evident in the spectrum shown for the Mitras Lightbar 2 Daylight on your website? The blue peak occurs at approximately 455nm. Also, there is very little light in this spectrum at deep red wavelengths. The peak absorption wavelengths for chlorophyll a are 430nm and 662nm but the spectrum that you show has very low/low output at these wavelengths.
