From Wikipedia, high pressure sodium lamps use xenon, whilst low pressure ones use neon with a small amount of argon. See entry for 'sodium vapor lamps'

Why argon and neon gas used in sodium vapour lamp?

Argon gas is used in sodium vapor lamps to provide the starting mechanism for the lamp. When the lamp is turned on, the argon gas helps facilitate the initial discharge of electricity through the lamp. Neon gas is used to help improve the color rendering of the lamp, making the light emitted appear more natural and pleasant.

What is hpsv lamp?

HPSV stands for High Pressure Sodium Vapor lamp. It is a type of high-intensity discharge (HID) lamp commonly used for outdoor lighting, street lighting, and agricultural applications due to its high energy efficiency and long lifespan. HPSV lamps produce a warm white or yellowish light and are known for their ability to provide good visibility and color rendering.


What items do high pressure sodium grow lights kits usually contain?

What are the benefits of using a high pressure sodium lamp for outdoor lighting?

High pressure sodium lamps are beneficial for outdoor lighting because they are energy-efficient, have a long lifespan, provide a bright and consistent light output, and are cost-effective in the long run.


Principle of working of a sodium vapour lamp?

In a low pressure sodium vapour lamp, argon or neon gas is first heated up to emit a slight red or purple glow. The heat from this warms sodium metal in the light to the point of vaporizing, which is when the familiar yellow glow begins.


What is the type of gas in an arc lamp?

The type of gas commonly used in an arc lamp is typically a noble gas such as xenon or mercury vapor. These gases are chosen for their ability to produce a bright and steady light when an electric current is passed through them in the lamp.


How does a getter work in a high pressure sodium lamp?

I believe it's there to remove impurities from within the outer glass envelope that would otherwise attack the arctube


How can you tell if the halophane light you have is a metal halide or high pressure sodium?

If you have one or more of each type working, it is easy to tell the difference, a metal halide lamp produces a wide spectrum very white light, the high pressure sodium is a narrow spectrum light that is very yellow. If you just have the light fixture, and need to know what kind of lamp it is made for, the lamp type is often mentioned on the ballast nameplate or a small sticker near the lamp socket. If that does not work, a metal halide ballast will usually be two pieces, a transformer with a heavy laminated metal core, and a capacitor in a silver can. The sodium lamp ballast will have these also, but in addition it will have a lamp striker in a second silver can, or a plastic module. In other words Metal Halide ballast: 2 pieces, HPSodium ballast: 3 components.
