Abstract: There is provided a light emitting device, for example a grow-light, comprising: a first solid-state light source that generates blue light with a blue photon flux; and a second solid-state light source that generates red light with a red photon flux; wherein a ratio of the blue photon flux to red photon flux is from about 1:3 to about 3:1. It may be that the broadband blue light substantially matches at least one of: the absorption peak wavelength of chlorophyll-a; the absorption peak wavelength of chlorophyll-b; and the absorption peak wavelength of carotenoid.
