2. Inputed voltage: AC100-240V,Convenient usage, application for all countries.
3. LED power supply with isolation project, safety usage.
4. Lifespan more than 50,000hours.
5. Aluminum Alloy with high heat conduction, make sure of the normal working time.
6. Apply for plant growing, flowering, fructification.
7. Light ratio: red 660nm: blue 460nm: 3:1,Red light promote the flowering,fructification;Blue light promote the growth of leaf, you can customize different LED ratio according to different plants.
Analysis
Part of circuit for LED source are connected with high power LED 1w, LED1, LED2,....LED 20 in series,.respectively 15pcs red light 1w led and 5pcs blue light 1w led. Voltage for red: 2.0-2.4V, Blue: 3.0-3.4V,Current:: 350mA
the power of LED Diodes: (45-55)V * 0.35A=15.75W-18.55W
Inputed Power (the efficiency of driving 88%)= (15.75-18.55)W/0.88=(17.9-21)W
Application
1. As a supplimentary lighting source, strengthen the light intensity, extendingthe lighting time.
2. According to different plant needs, it can control the light which plant need.
3. In replacement of natural light in the greenhouse, efficiently promote the growth of plant.
♦Why is blue light important for plants?
Blue light stimulates Chlorophyll production more than any other color, encouraging thick leaves, strong stems and compact vegetative growth.
Blue color is good for leaf and root growing.The wavelength have 450nm and 470nm, if your botany only leaf ,we recommend us 470nm, if you wanna it is good for root, so we recommend use 450nm
♦Why is red lightimportant for plants?
Red light is very important to plant reproduction. Phytochrome pigments absorb the red and far red portions of the light spectrum and regulate seed germination, root development, tuber and bulb formation, dormancy, flowering and fruit production
red is good for blooming ,the wavelength is 660nm and 630nm, if you plant flower,we recommend you use 630nm, if you plant blossom and yield fruit,we recommend you choose 660nm

Grow tips:
1: Given the led grow light emits much less heat than other light source ,Your plants will need less water ,Wait f or your soil to dry a little bit before watering or at least make sure your plants really need to be watered.
2: Temperature is very important element in the photosynthesis process ,For the same reason as the previsous point ,Maintain the ambient temperature between 20-30degree for normal plants growth.
3: With led grow light ,your plants need fewer nutrients.
4: For better light penetration ,it's preferable to light serveral small plants rather than a few large ones .
Attention:
1. It works under the environmental of normal temperature.
2. Due to the function of nonwaterproof, it can’t pour the water.
3. The parameter for LED ratio(red:blue 3:1) are our standard light ratio,just for your reference,customer can choose different LED ratio according to your different needs.
4. the lighting area of LED and suspended Heigh
