Because leds ZhuDeng product price down a lot now, cause the overall LED street lamp products to a much lower than the previous two years. But the choice of LED lights do not blindly choose, you need to understand light pole height, the material of street lamp, street light, the quality of the style of street lights, and then is its price. If LED lighting lamps light shell quality time, not strong enough, we don't choose. And there are some lamps and lanterns is called 30 w LED street lamp does not need aluminum radiator, these are the fallacy, even though overall LED street light prices can fall a lot but poor heat dissipation products will lead to the LED light source in a very short period of time the light failure, cause life is short, lamps and lanterns is not bright, severe cases will die lamp etc. Phenomenon, so I need to ask factory, again to buy. Square LED street lamp lighting should be around 10 meters, the center in the majority with 12 ~ 15 meters, 1000 regular square lamp, lamp pole height should not be high, 10 meters to choose 60 w ~ 80 w, 10 meters above 100 w, the price you get what you pay for, as long as you buy the quality is absolutely worth the price.
