NettetSPD is the Spectral Power Distribution of a light source. The visible white light that we see is made up of a spectrum of various colors of light, ranging from wavelengths of 380nm (violet) to 760nm (red). The SPD is a graph that shows the power (strength) of each wavelength of light produced by a particular light source. Nettet31. mai 2024 · Red + blue light is not superior to white light for plant growth. To the contrary, the LUE of red lettuce ‘Rouxai’ under warm-white light was at least 26% higher than under red + blue light when the blue fraction was at least 11%. It was 33–40% higher compared to red + blue light when the blue fraction was 33%. NettetThe majority of white LEDs being used today are made from a blue LED pumping a longer wavelength visible phosphor. Color rendering index (CRI) is a measure of the spectral matching to sunlight. 100 is considered to be the same as sunlight and most LEDs used in general illumination today have a CRI greater than 80. providence credit union northern california
