100 what is the price of solar street light1

Believe that many buyers often encounter more puzzled when the choose and buy the LED street lamp, I don't know how to choose a good street lights, shandong street lamp manufacturers today teach you how to from the Angle of the manufacturer to choose an appropriate lamp. First, the LED light failure and photosynthetic efficiency of ordinary light now

I believe a lot of buyers when buying LED lights are often confused, don't know how to choose a good street lights. Today, shandong street lamp manufacturers will teach you how to choose appropriate from the perspective of manufacturer of street lamp. First, the light emitting diode light attenuation and light efficiency at present, the common light source the light efficiency of about 110 ~ 130 durham/tile, if we meet with higher light efficiency, our manufacturers generally recommend that you do not choose, we also recommend that power should be 1 w/a. If too much, won't have too big impact for actual use. Don't blindly listen to those manufacturers boast that the power can reach 1 watt. Not make too much difference in the actual use, so the best is to use a watt one watt. When the power is less than 1 w/a, is not recommended, because when the power is less than 1 w/light attenuation will be very serious, if the light attenuation is serious, the whole life will be greatly reduced. As a result, many products through the use of surface data and the original can not only see that it is good or bad, only to wait for a long time to find these faults. Therefore, you need to have a pair of discerning eyes to identify them, and listen to your ear means seeing is believing. Second, the luminous efficiency higher luminous efficiency, lighting effects, the better, the better the energy saving effect, the lower the energy consumption, which is environmentally friendly. Third, led street light heat dissipation theory, the service life of power leds about 30000 to 50000 hours, if the light inside the radiator, will further extend service life, so try to choose the light that built-in radiator. Fourth, unit weight of led street lamp led street lamp don't too heavy; The more they is heavier, the materials used. Depending on your specific requirements and configuration. With the development of science and technology, the future of led lamp will like electronic products more and more light, and longer service life. The above four lights also choose the four points. Listen to so much today, I believe that you should know the shandong lamps manufacturer's recommendations.
