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. 660Nm Led Grow Light, Led Grow Light 12V Dc , Spider Grow Light , Cidly Led Grow Light ,Fiber Optic 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,USA, Bahamas,Malawi, Cologne.Not long ago, Taga City, Miyagi Prefecture, Japan, publicly demonstrated the world's largest LED (light-emitting diode) artificial phototype plant factory to the media. The plant, called Miraihata covers an area of about 2,300 square meters and uses 17,500 LED lights, which can be produced throughout the year and is expected to harvest about 10,000 lettuce trees per day. Not long ago, Fujitsu also announced that after about a year of preparation, low-potassium lettuce produced in its own plant factory began to be put on the market.
