Hps 70w 110w 250w 400w 1000w High Pressure Sodium Lamp

 
Features
High pressure sodium lamp starts, in the initial stage is mercury vapor and low-pressure discharge of xenon. At that time, the light bulb working voltage is very low, the current large; To continue with the discharge process, the arc temperature rise, mercury, sodium vapour pressure is decided by the discharge tube cold end temperature, when the discharge tube cold end temperature to achieve stability, discharge will be stable, bulb of luminous flux, work voltage, current and power are in normal working condition. Under normal working conditions, the whole process takes about 10 minutes.
