Plants under natural light in the whole spectrum of evolution , growth, maturity. The sun within LED Bulb the visible light spectrum in the 690 ~ 780nm, 580 ~ 690nm, 350 ~ 530nm wavelength light between the physiological activities of the strongest band , and the absorption of chlorophyll in plants , photosynthetic efficiency ,
phototropic , light built induction and long-wave red light red light- induced biochemical reactions five major plant action spectrum ( see Figure 1 ) is consistent. Green plants chlorophyll to red light and blue light absorption ability, red plants vivo carotenoids lutein and for green and blue spectral absorption ability.

2.2 light quality on the growth of aquatic animals
Light as an important ecological factor in nature , the impact on animal behavior is extremely obvious. Different light intensity, photoperiod and spectral composition on predation rates , metabolism , growth , reproduction, have a certain influence . Overall, the ornamental fish for short-wavelength light environment is not very adaptable , as the wavelength increases, the growth rate of the fish is gradually increased.
