Our product has two-year warranty. Specification:Product name: LED Plant Growth LampVoltage:AC 85V-265VLED type: SMD2835LED quantity:126leds (90 red+36 blue)200leds (166 red+34 blue)300leds (228 red+72 blue)Base: E27Beam angle: 120°Lifespan: 50000 hoursProduct size: 80mm×93mm Features:*Hydroponics Systems equipment, brand new and immoderate quality.*With a radiating hole design, effective warmth dissipation, drastically extending the provider life, making the carrier life up to 50,000 hours.*E27 normal lamp holder, suitable for many countries.*Stable performance, safety, energy saving and environmental protection.*Blue Light: High absorption by chorophyII and carotenoids, wide impression on photosynthesis. For plant growth and absorption. Can develop chloroplast activity, to prevent spindling plant, but on the diversified hand, it will inhibition of photosynthesis, so that the plant desires a lot blue light.*Red Light: ChorophyII absorption fee is low, has a significant affect on photosynthesis and photoperiod effect. For plant flowering and fruiting, promote plant growth, germination, flowering, results. The maximum dominant function during including color on the plants, accelerate photosynthesis ~ 315nm impact on morphological and physiological processes is minimum nm ~ 420nm chlorophyll absorbs less affect photoperiod effect, prevent stem elongation nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the most important proportion, the greatest impression on photosynthesis nm ~ 620nm dye absorption fee isn't excessive ~ 750nm (red) chlorophyll absorption payment "high", has a significant affect on photosynthesis and photoperiod effect ~ 1000nm absorption rate, stimulate mobile elongation, influence of flowering and seed germination.> 1000nm switched over into calorie.
