* Item: Plant growth lamp * LED Chips: 2835 SMD * LED Quantity: 48Leds/60Leds/80Leds * Input Voltage: AC 220V ~ 240V * Lifespan: 50000hours 1.280nm ~ 315nm influence on morphological and physiological processes is minimal. 2.315nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation. 3.420nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis. 4.500nm ~ 620nm dye absorption rate is not high. 5.620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect. 6.750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination. 7.> 1000nm converted into calorie.
