LED Stree Light is the best choice for energy saving retrofits in street lighting today. How do I buy LED Stree Light and what are the shopping points? We will briefly introduce the purchase instructions starting from 4 points.

1.Luminous efficiency

With the maturity of LED lighting technology, high-power LED light source can meet the luminous flux required by ordinary street lights. Generally speaking, the luminous flux of high-pressure sodium lamp is 100LM/W, commonly used high-power LED for 50-60LM/W, is the best foreign LED chip, can reach 80LM/W. The higher the luminous efficiency, the better the energy-saving effect. This is one of the most important indicators for choosing LED street lights. However, the standard of LED is not explicitly stated, so it must be carefully checked when buying LED street lights.

2. Light attenuation

At present, some businesses use hundreds of 0.5W low-power led in order to reduce the cost and lower the price of LED Stree Light. however, the light decay of this low-power LED is very serious, up to 80%, lasting only 1000 hours. Therefore, as a street light that needs to be used for a long time, this low-power LED is absolutely not allowed. If you choose high power LED (usually above 30W), the light decay effect will be much better.

3. Street light weight

Due to the high technical content of LED Stree Light and complex parts, the weight of some high-power lights far exceeds that of ordinary high-pressure sodium, so the corresponding supporting materials are more demanding. However, some LED street light companies have the trend of minimizing the weight of LED lights, from the original single lamp 30 kg to more than 10 kg.

4. Thermal value

Because LED is a semiconductor device, the chip is affected by the temperature, down to 30% of the initial speed of light, it loses the meaning of lighting. That is to say the end of life. Theoretically, the life of high-power LED Stree Light is 30,000-50,000 hours, but the important prerequisite is good heat dissipation.
