How many watts does the LED street light have?
The technology is mature day by day, and the high-power LED light source can meet the needs of general street lamps. The general optical efficiency of high pressure sodium lamp is 100LM/W, high power LED is commonly used by foreign 50-60LM/W, the best LED chip can reach 80LM/W, the luminous efficiency is high, means that the energy saving effect is better, which is the choice of one of the most important indicators of LED street lamp. However, the LED standard does not specify this, so the purchase of LED street lamps must be carefully confirmed.
And some businesses, in order to reduce costs, use hundreds of 0.5W small power LED. However, the small power LED light is very serious, its decline to 80% of the life of only 1000 hours. So, as the need for long-term use of lamps is not allowed by this small power LED, with high power LED (usually above 30W), the light will be better.
LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction.
