rare earth grow light

1. suggest using waterproof E27 Base 2. working voltage 220V±30V 3. Working frequency 50HZ 60HZ 4. Warranty 2 years(usage life 8000hrs) 5. Pipe temperature 60°C±5°C 6. Lm: 20 Lm±2 Lm/W Using domain of plant growth lamps and spectral test report The using domain of plant growth lamps:applied in the greenhouse(especially in winter),the vegetables and fruits at the time of nursery,growth and production,the lamps can strengthen the photosynthesis. The components of the plant growth lamps: 1. Glass exposed pipe of energy-saving lamp 2. Electronic ballast 3. (E27)Lamp adapter 4. Primary fire-resistant plastic parts 5. Rare earth phosphor powder of 4700K(±5%) in color temperature 6. Lamp shell made fromaluminium alloy The connecting relationship and the principle of the components: The plant growth lamps work like energy-saving lamps,but the difference is the plant growth lamps use rare earth phosphor powder of 4700K(±5%) in color temperature,we use Eu of rare earth elements, most of Europium Oxide are appied to phosphor powder,Eu3 is used as activator of red phosphors.Eu2 is appied to blue phosphors,Tb is used as activator of green powder in the phosphor powder,for example,Phosphate matrix and Cerium magnesium aluminate matrix activated by Tb all give green light.Dy is used as activator of phosphor powder, trivalent dysprosium is a promising single luminescent center tricolor of activated ion,it mainly consists of two emission strips,one emits yellow light,another emits blue light. The advantages of the product: Here is a spectral test report,we can find the lights emitted by plant growth lamps contain light of different colors.The small amount of purple light of 400-420nm helps create anthocyanins and resist the elongation of branches.And the blue light of 450-460nm can strengthen the stem and leaf,increase the growth of the plants,and adjust stoma to open .The green light of 550nm can promote the growth of oxygen,and help the plants store nutrients,the yellow light of 580nm can promote the growth of root and germination.The large amount of red light of 650-660nm can promote the growth of the plants especially in bloom and fruit,and increase the speed of growth(advance of 20 days in blooming,advance of 30 days in harvest), also increase 25%-35% of the number of fruits and reduce the rate of the odd fruits.Besides,the visible light of these lamps is one kind of electromagnetic waves, and a little ultraviolet can prevent the diseases and insects
