LED grow light supplementary light technology is a new technology that has emerged with the development of LED in recent years. A large number of studies and applications of LED plant growth light in facility cultivation environments show that it can solve the light quality in the spectral components of other artificial light sources. Impurity, inconsistent light intensity, and low energy efficiency of light source irradiation. The use of Led Plant Grow Light can significantly promote the development of spinach, radish and lettuce, improve morphological indicators, and increase their growth rate and photosynthetic rate by more than 20%. The aluminum fins of the Led Plant Light are made of aviation aluminum square pattern (thickened aluminum) to ensure heat dissipation efficiency and prolong service life.
