What is sodiam lamp?

Sodium lamps are a type of high-pressure sodium vapor lamp that produces light by passing an electric current through a mixture of gases and sodium vapor. They are commonly used for street lighting and outdoor security lighting due to their high efficiency and long lifespan.

Sodium lamps emit a yellow-orange light that is very similar to the color of natural street lighting, making them ideal for nighttime illumination. They are also known for their high luminous efficacy, meaning they produce a lot of light for the amount of energy they consume.

One drawback of sodium lamps is their relatively long warm-up time, as they take several minutes to reach full brightness after being turned on. Additionally, they have a characteristic cycling effect where the light output fluctuates slightly as the lamp ages.

Overall, sodium lamps are a popular choice for outdoor lighting applications due to their energy efficiency, long lifespan, and distinct color temperature.
