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. Lm561C Grow Light, 320 Watt Monster Board Grow Light , Daisy Chain Led Grow Light , Bar Led Samsung Grow Light ,Grow Light 301H . LED is used as a light source for indoor lighting, and there are still certain problems with lighting effects. The efficiency, color and service life (attenuation of light) of individual luminaires, as well as the quality of illumination, are not ideal. Although LED illumination is very high and energy consumption is very low, this does not mean that the efficiency of LED lamp light is high, because its overall lighting quality is not high. In addition, LED lighting fixtures need to avoid too strong glare LED grow light features and introduction. Only when the temperature is suitable LED lighting fixtures can be very long, once made into poor quality lamps, in high temperature and closed environment, the lighting effect will drop sharply. The product will supply to all over the world, such as Europe, America, Australia,Berlin, Miami,Nigeria, Bangkok.With the extensive development of the LED industry, LED companies are constantly looking for new development outlets, LED grow lights are undoubtedly to give LED companies a chance to be reborn, but despite the prospect of plant grow lights, the development of plant factories still faces some bottlenecks. For example, the early investment is too large, and an artificial light plant factory with a daily output of 1,000 lettuce plants generally requires a relatively high initial investment. Even if the government subsidizes 50%, it usually takes 5-7 years to become profitable. In addition, the planting technology in the era of factory agriculture has yet to mature, and the related quality control, logistics and sales models are also being explored.
