What is sodium lamp?

Sodium lamps, also known as sodium vapor lamps, are a type of high-pressure gas discharge lamp that produces light by emitting sodium vapor. These lamps are commonly used in street lighting, parking lots, and industrial settings due to their high efficiency and long lifespan.

Sodium lamps produce a characteristic yellow-orange light, which is often perceived as having poor color rendering compared to other types of lighting. However, they are known for their high lumen output per watt, making them an energy-efficient choice for outdoor lighting applications.

There are two main types of sodium lamps: low-pressure sodium lamps and high-pressure sodium lamps. Low-pressure sodium lamps produce a monochromatic yellow light, while high-pressure sodium lamps produce a broader spectrum of light with a warmer, more natural color temperature.

Overall, sodium lamps are a cost-effective and energy-efficient lighting option for outdoor and industrial applications, providing reliable and long-lasting illumination.
