About the effect of light wavelength on plant growth: 1. 280 nm ~ 315 nm has little effect on morphological and physiological processes. 2. Chlorophyll absorption at 315nm~420nm has little effect on the photoperiod effect and prevents strain elongation. 3. The absorption ratio of chlorophyll and carotenoid is the largest at 420nm～500nm, and has the greatest impact on photosynthesis. 4. The absorbance of dyes at 500nm~620nm is not high. 5. Chlorophyll absorbs "high" at 620nm-750nm, which has an important influence on photosynthesis and photoperiod effect. 6. 750nm~1000nm absorbance, stimulate elongation, affect flowering and seed germination. 7. > 1000 nm converted to calories.features: 1. 180-degree adjustable angle installation, which can meet the lighting effects of different environments and achieve directional lighting. 2. There are three installation methods (wall-mounted, ceiling-mounted, seat-mounted), the installation is very simple, just use the screws on the rear U-shaped bracket to fix the installation position. 3. Two power supply methods, three-wire input, better protection circuit, to ensure the safety of electricity use. Two-wire system with plug input, a variety of plug specifications, in line with multinational electricity standards.
