Low Pressure Sodium Light Bulbs

First produced in the 1930s, low pressure sodium light bulbs have a long history of providing efficient light with a monochromatic yellow hue.

How Low Pressure Sodium Lamps Work

Low pressure sodium bulbs have a glass discharge tube that contains solid sodium with neon and argon gas. When electricity is sent through the lamp, it begins to glow with a slight red or pink light as the gases and sodium warms. Once the sodium metal warms it vaporizes, creating a bright yellow glow. Surrounding this inner discharge tube is an outer glass vacuum envelope that provides thermal insulation and improved efficiency.

Benefits of Low Pressure Sodium Bulbs

A low pressure sodium bulb provides one of the most effective light sources available, with the capability of producing up to 200 lumens per watt. This makes them ideal for settings that require ongoing lighting, like outdoor or underground lighting. Low pressure sodium bulbs also do not decline in lumen output as they get older. They do have one drawback, however: The light from a low pressure sodium bulb is at a wavelength that is near the peak sensitivity of the human eye. This means that the items illuminated by the yellow light from the bulb may not be easy to distinguish or see, and the light produced by the bulb can often appear dim.

Common Uses of Low Pressure Sodium Light Bulbs

Low pressure sodium lights take a while to warm up and provide the yellow glow that is hard to see. For this reason, they are commonly used in outdoor lighting settings where a true daylight color rendition is not important — such as streetlights, lights in tunnels and security lights.
