Plants cultivated with natural spectrum LED "Sun Like" grow faster than plants cultivated with ordinary white LED, and contain more antioxidants, Flavonol.
The comparison experiment used Sun Like LED with the same color temperature and brightness (200 ol/m2s) and general white LED to irradiate lettuce, and measured the weight and flavonol content of lettuce two weeks later. The difference between the two LED lies in the arrangement of the spectrum (Spectrum) light wavelengths. Sun Like products have a spectrum curve similar to that of natural light.
The results of this experiment show that the weight of lettuce cultivated with Sun Like is 43.0g, which is 13.5% more than the weight of lettuce cultivated with ordinary white LED (37.9g), so it is more effective in promoting plant growth; the antioxidant substance flavonol content (Sun Like 0.55) is also 41% higher than the average white LED (0.39). The results of this experiment show that Sun Like LED, which is similar to the solar spectrum, has the effect of shortening the growth time of plants, improving plant quality, and increasing the value of crops.
Nam Ki-bum, deputy general manager of the Seoul Semiconductor Sales Division, said: "The results of this experiment show that when choosing to light for indoor crop cultivation, the priority factors are not color temperature and brightness, but the spectral curve of LED emission and sunlight. The degree of similarity between Seoul Semiconductor’s Sun Like products is an LED light source that achieves high standards in the natural spectrum industry and an ideal solution for plant growth. Our products will help growers harvest stable quality crops throughout the year and improve the crop growth environment."
The competitiveness of Seoul Semiconductor's Sun Like products has been recognized by the industry. The company has become a lighting company Rofianda B. V. Supply lighting for indoor farm gardening.
