1. Comparison of solar street lamp price and electricity fee: The annual electricity fee generated by using 60W LED street lamp is only 20% of the annual electricity fee generated by using 250W ordinary high-pressure sodium lamp, which greatly saves electricity consumption. It is an ideal energy-saving product and conforms to the trend of building a conservation-oriented society.

2. Comparison of the Price of Solar Street Lamp

The power of LED street lamp is 1/4 of that of ordinary high-pressure sodium lamp. The cross-sectional area required for copper cable laying is only 1/3 of that of ordinary street lamp, which saves a lot of laying cost.

Combining the above two cost savings, the use of LED street lamps can make the owners recover the cost of the initial increase in investment in one year compared with the use of ordinary high-pressure 

sodium lamps.

3. Illumination contrast: The illumination of 250W high-pressure sodium lamp can be achieved by using solar street lamp LED 60W, which greatly reduces the use power. Because of its low use power, LED street lamp can be combined with wind energy and solar energy and used on urban secondary trunk roads.

4. Use Temperature Contrast

Compared with ordinary street lamp, LED street lamp produces a lower temperature in the use process, continuous use will not produce high temperature, no blackening, no burning black lampshade.

5. Safety performance comparison

At present, the cold-yin lamp and electrodeless lamp in the market are all X-ray illuminated by high-voltage pole, which contains harmful metals such as mercury, and harmful rays. Compared with them, LED street lamp is a safe low-voltage product, which greatly reduces the potential safety hazards in the process of installation and use.

6. Comparing the Price and Environmental Protection Performance of Solar Street Lamp

Ordinary street lamps contain harmful metals and spectra contain harmful rays. In contrast, LED street lighting spectrum is pure, does not contain infrared and ultraviolet rays, no radiation, no light pollution, and does not contain harmful metals, waste can be recycled, belongs to the typical green environmental lighting products.

7. Comparing the Price, Service Life and Quality of Solar Street Lamp

The average service life of ordinary street lamp is 12 000 hours. It is not only expensive to replace street lamp, but also affects traffic. It is especially inconvenient to construct in tunnels and other places. The average service life of LED street lamp is 50 000 hours, which is 10 hours per day. The service life of LED street lamp is more than 10 years, once and for all. In addition, the waterproof, impact resistance and shock resistance of LED street lamps are very good, the quality is stable, and they are maintenance-free products during the shelf life.
