Startup performance comparison
LED street lights are activated instantaneously, and it takes more than 10 minutes for high-pressure sodium lamps to start to reach normal brightness, and high-pressure sodium lamps consume a lot of electricity during this time. The input voltage of the LED street light can be between 90 volts and 305 volts and has no effect on the LED lights. The high-pressure sodium lamp cannot be started when the input voltage is less than 185V, and the power increases by 12% when the input voltage exceeds 245V. In this way, high-pressure sodium lamps have higher requirements on power supply lines.
