400~520nm (blue) – This wavelength can directly develop plant roots and stems, and has the largest absorption ratio of chlorophyll and carotenoids and the greatest impact on photosynthesis. Grow Light 4000W, Full Spectrum Led Grow Light , Plant Grow Light , Ufo Grow Light ,300W Led Grow Light . In terms of illumination, LED lighting can guide the space, create a pleasing lighting environment, convey the value information of the space, and render the space with light. In terms of color temperature, the cooling and warm feeling of the lighting effect formed by the light source of different color temperature of the LED complements the difference in climatic conditions, and the designer makes the indoor space full and enjoyable through the grasp of the color temperature of the light. In terms of light efficiency, LED lighting can reduce energy consumption (high light efficiency). In addition, LED lighting also does not produce infrared radiation and ultraviolet rays, low temperature, long life, energy saving and other advantages, since this is the case, then why LED lighting is not the darling of indoor lighting? What are its disadvantages? The product will supply to all over the world, such as Europe, America, Australia,Bahamas, luzern,Peru, Ireland.Taiwan has also begun to smell the business opportunities of plant factories, and many LED companies have already begun to cut into the market in this field, in addition to Jingdian, Yiguang, there are also Guangyuan, Guangding, Hongqi, Guanghui, New Century, Dongbei, etc., and the Economic Construction Commission has also begun to support plant factories through pipelines last year to promote the activation of Taiwan's agriculture.
