Product Specifications: Item: Plant growth lamp LED Chips: 2835 SMD LED Quantity:48Leds Input Voltage: AC 220V Lifespan: 50000hours Base Type: E27/E14/B22/GU10/MR16 Spectral range effects on plant physiology: 1.280nm ~ 315nm influence 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 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. Features: Full spectrum that is necessary & critical for plants growing & flowering (from seeding to harvest). Plants like the 525nm Green the way they look like. More healthy if plants are in enough green appearance. 450nm Blue & 630nm Red is accelerating leaf growing. 660nm Red is promoting flowering. 7000k White is to be replacer of HPS,HID,MH. Perfect for small Grow Box,Grow Tent,DIY Hydroponics,Bonsai,Garden... etc. Comfortable, Humanistic & High-performing.
