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

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?

The High pressure sodium grow lights kits usually contain a ballast, a reflector, a lamp, a power cord and plug. But, the items may vary by the brands of kits you purchase.


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.


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.


What is SON lighting?

SON stands for high-pressure sodium. It is a type of lighting technology that uses a sodium vapor lamp to produce light. SON lighting is often used in outdoor and street lighting applications due to its high energy efficiency and long lifespan.


Can you use a 70 watt high pressure sodium bulb in a 100 watt ballast?

No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all


Do you need a ballast for HPS lights?

Yes, all high pressure sodium fixtures require a ballast to operate the fixture's lamp. Most of these industrial fixtures come with a multi tap primary on the ballast so that they can be used on multiple voltages.
