What is ballast High-Intensity Discharge?

High-intensity discharge lamps (HID lamps) are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.

How types of ballasts are available to the HPS lamp?

There are two lamp families that work with a ballast: fluorescent and HID. And there are two types of ballasts in each family: magnetic and electronic.

Which are high-intensity discharge lamps?

Types of High-Intensity Discharge Lamps

  • Mercury vapor lamps. Mercury vapor lamps are widely used to light both indoor and outdoor areas such as gymnasiums, factories, department stores, banks, highways, parks, and sports fields.
  • Metal Halide lamps.
  • High-Pressure Sodium (HPS) Lamp.

How does a high-intensity discharge lamp work?

What are they? HID, or high-intensity discharge light bulbs and lamps, are a family of gas-discharge arc lamps which create light by sending an electrical discharge between two electrodes and through a plasma, or ionized gas.

What are the four types of HID lamps?

There are five main types of HID lamps:

  • Metal halide.
  • High pressure sodium.
  • Low pressure sodium.
  • Mercury vapor.
  • Ceramic metal halide.

What are the different types of ballasts?

There are two categories of ballasts – magnetic and electronic. Magnetic ballasts are the most basic type and operate bulbs through a core and coil transformer.

How do you tell which HID bulb you have?

One way to tell if a vehicle is equipped with HID headlamps is to look at the outer lens cover. If the headlamps are HID, the markings D1R, D1S, D2R or D2S will be displayed on the lens. These are the four basic types of HID bulbs that are used in HID lighting systems.

Do HID lamps start instantly?

Restart time – Restart time for hot HPS lamp on average is 1 – 2 minutes, but for applications where continuous lighting is needed, special standby lamps are used that can maintain two arc tubes, allowing the lamp to restrike instantly.
