Color performance is better than highvoltagesodiumlamp when use LED as light source, the color rendering index of highvoltagesodiumlamp is 23 only, while LED street light is more than 70.
Constant power output characteristics can avoid prodigality caused by super-brightness when voltage of high-voltagesodiumlamp exceeds 220v.
恒功率输出特性避免高压钠灯在高于220v标准电压时会产生超亮度浪费。
