8. High power factor advantages:
The power factor of the sodium lamp is only 0.45, the additional power can only reach 0.85, the effective utilization rate of the power grid is low, while the power factor of the LED street lamp can reach 0.95, and the effective interest rate of the power grid is high.
In summary, compared with traditional high-pressure sodium lamp, high-power LED street lamp has obvious advantages in all aspects, especially in energy saving, energy saving rate of more than 60%; maintenance costs have decreased significantly, and green environmental protection, has perfectly ended the traditional sodium lamp, becoming the second choice for road lighting.
