Why engineer chose this LED as your plant growing design?

Through the study and investigations, we have seen that LED devoted her all life to the cause of agricultural production. it is because of this, farming is beginning to be Intelligentization . When compared to traditional Incandescent or fluorescent lamps . the greatest advantages of this LED are exact controllability of wave length .
