Common uses: large areas like parks, street lighting, high ceiling buildings, gyms. Low pressure lamps with a quartz envelope are used for germicidal purposes since they allow UV light to pass.
There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). These lamps are mostly used for street lighting as well as industrial uses. The lamp works by creating an electric arc through vaporized sodium metal. Other materials and gases are used to help start the lamp or control its color.
High-intensity discharge (HID) lamps are similar to fluorescents in that an arc is. Mercury vapor lamps are widely used to light both indoor and outdoor areas .
