Recently, horticulture lighting is one of the popular lighting applications. Not only can it replace conventional high-pressure sodium lamps, but it also can be used on the different color of LEDs with necessary tuning, so that wavelengths required for every stage of plants growth can be supplied. Horticulture lighting can be divided into top lighting and inter lighting. Top lighting supplies common plants basic light source for photosynthesis while inter lighting supplies extra light for the purpose of expediting fruit growth. By now, MEAN WELL has accumulated a variety of field cases in horticulture lighting application and will be ready to launch centralized system power solution to fulfill power needs of horticulture lighting in the near future.
