400W LED, Full Spectrum Deformable Grow Light For Plants. Feature: Super shape with high lumen output makes it a super bright LED grow light. Advanced cooling system with aluminum alloy heat dissipation. More stable and safe - premium aluminum alloy heat dissipating, high temperature resistant and corrosion resistant. The three aluminum LED heads are adjustable. They can be folded up to 90 degrees, which will make the light cover a wide area. Waterproof rating IP65, dustproof and waterproof, use indoors and outdoors, more safe. Hanging kit makes this grow light much easier to mount, excellent heat control LED chips help your plants grow better. For all types of flowering plants: such as for tomatoes, chili, eggplant, rose etc. All types of vegetables: for herbs and leafy vegetables, lettuce, pak choi etc. Also suitable for indoor gardens or indoor potted plant landscapes. Usage: For greenhouses, grow boxes, grow tents, hydroponic system equipment. Blue light: High absorption of chlorophyll and carotenoids, great impact on photosynthesis. For plant growth and absorption. Can improve chloroplast activity, to prevent spindly growth, but on the other hand, it will inhibit photosynthesis, so the plant needs a lot of blue light. Red light: Chlorophyll absorption rate is low, has a significant effect on photosynthesis and photoperiod effect. For plant flowering and fruiting, promote plant growth, germination, flowering, results. The most dominant role in adding color to plants, accelerating photosynthesis. 1. 280nm ~ 315nm impact on morphological and physiological processes is minimal. 2. 315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation. 3. 420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis. 4. 500 nm ~ 620nm color absorption rate is not high. 5. 620nm ~ 750nm (red) chlorophyll absorption rate \"high\", has a significant impact on photosynthesis and photoperiod effect. 6. 750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination. 7. > 1000nm converted to calories.
