E27 Led Grow Light

E27 110V LED Plant Grow Light Lamp Growing Lights Bulbs for Flower Plant Vegetable Green House Features: 1. The combination of red and blue light is more consistent with the light intensity needed for plant growth. 2. Different amounts of LED match, light intensity accords with the light needed in the process of plant growth. 3. E27 lamp head is more widely used, and the household lamp head can be used in contact. 4. Scope of application: lighting of plant growth and planting vegetable lighting in Greenhouse Specifications: Material: Plastic Source material: three chip 2835 LED lamp Product weight: approx.15g Rated voltage: 220V Lamp head model: E27 Product certification: CE, RoHS Product size: approx. 55*45*45mm/2.16*1.77*1.77'' Model Power  Blue Light Quantity   Red Light Quantity   Illuminated light 72LED 5W 20pcs 52pcs 400LM The effect of spectral range on Plant Physiology: 1. The impact of 280nm to 315nm on morphological and physiological processes is very small. 2. 315nm ~ 420nm chlorophyll absorbs less photoperiod effects to prevent stem elongation. 3. 420nm ~ 500nm (blue) has the largest proportion of chlorophyll and carotenoid absorption, which has the greatest impact on Photosynthesis. 4. 500nm ~ 620nm dyestuff absorption rate is not high. 5. The "high" chlorophyll absorption rate of 620nm ~ 750nm (red) has a significant effect on Photosynthesis and photoperiod effects. 6. 750nm ~ 1000nm absorbance, stimulating cell elongation, affecting flowering and seed germination. 8. > 1000nm conversion into calorie. Note: Please allow 1-3cm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
