Hydroponic, soil Feature:-Using high-quality LED light source, lifespan is up to 50000 hours-Can replace 3-5 times the power of high-pressure sodium lamps, can save 80% of electricity than traditional high-pressure sodium lamps and metal halide lamps-Extra large heat sinks made of aluminum and quiet big fans to help heat dissipation. Easily reduce heat by 50%.-No replacing ballasts, bulbs or installing expensive exhaust systems to combat excess heat issues common with HPS rooms. -Different wavelengths of light have different effects on the photosynthesis of plants. The light required for photosynthesis of plants is about 400-700 NM wavelength, 400-500 NM.The (blue) light and 610-720NM (red) contribute most to photosynthesis.-Blue light helps plant photosynthesis can promote the growth of green leaves, protein synthesis, fruit formation; red light can promote the growth of plant rhizomes, contribute to flowering results and extend the flowering period, and play a role in increasing yield.-The irradiation area of the lamp will change accordingly according to different plants and environments, and the technical parameters will also change.-Good for plant growth/veg/flower/bloom/fruit stage ect. Package include:1 x 400W LED grow light 1 x Set hanging kits1 x Power cord
