It is with the highvoltage that the lamp starts keep it away from combustibles and explosive materials lest the fire happens.
点灯用的电压是高电压，应远离易燃易爆的物品，以免产生火灾。

Constant power output characteristics can avoid prodigality caused by super-brightness when voltage of high-voltage sodium lamp 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。
