In a high pressure sodium lamp a compact arc tube contains a mixture of xenon sodium and mercury.
High pressure sodium lamp lifespan.
The mercury vapor raises the gas pressure and operating.
We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs.
The heat generated by the arc then vaporizes the mercury and sodium.
