China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

High pressure sodium lamp is a gas-discharge lamp that uses sodium in an excited state to produce light. There are two varieties of such lamps: low pressure and high pressure. Low-pressure sodium lamps are the most efficient electrical light sources, but their yellow light restricts applications to outdoor lighting such as street lamps.[1] High-pressure sodium lamps have a broader spectrum of light than the low pressure, but still poorer color rendering than other types of lamps. Low pressure sodium lamps only give monochromatic yellow light and so inhibit color vision at night.

Once the lamp is selected, the next step is to select the ballast that will be used to drive it. When putting together a HPS ballast lighting system, it is very important to match the ballast to the lamp(s). An easy way to do this is by using the ANSI designation. For example, when using a lamp designated M-57, look for a ballast with that same designation.

High pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light. These types of lights are commonly found outside. They are used for things such as security lighting. They are also commonly found in an indoor garden setting. These types of lights efficiently produce a very high intense light. There is very little energy consumption. Here is a quick guide on how to test your high pressure sodium ballast to make sure it is properly and efficiently igniting the bulb.
