HID Light Bulbs – How Do They Work?

HID light bulbs are High Intensity Discharge bulbs that are used by those people who need brighter light when they are driving. As you must be aware, the headlights of most of the vehicles are halogen lights and these lights are not as bright as the HID lights. You will also see these lights in gyms, theme parks, ball games and stadiums.

Many people are now buying the HID or High Intensity Discharge light bulbs because these bulbs are very effective in producing extremely bright lights. What’s more, these bulbs can also cover very large areas. You may not be aware but these lights are available in various versions such as the regular high-pressure sodium lights, metal halide lamps and mercury vapor lamps.

The first HID or high definition lamps that were sold commercially were the mercury vapor lamps. After sometime, newer and better lamps started to be available in the market such as metal halide lamps and high-pressure sodium lamps.

How do the HID light bulbs create or produce light?

The HID or High Intensity Discharge light bulbs can produce light when the gas present inside the tube starts to heat up. When the gas becomes heated to the point of evaporation, light is produced. The tube contains tungsten electrodes and as the metal elements begin to heat up, they will strike these electrodes and as a result, light will be created.

HID lights are more or less like the fluorescent lights as they require ballast for the production of heat. Ballast is actually an instrument that is utilized to generate light. If the HID bulbs do not have ballasts then it will not be possible for them to produce lights because the reaction for the production of light will not start if there is an absence of ballast.

Tungsten electrodes: what are they?

Tungsten is actually an element (chemical) that is commonly known for its vigorous physical characteristics and high melting point. You will find this element in many electrical appliances and it is also found in HID lights. The color of tungsten ranges from steel gray to tin white.

What are HID lamps used for?

You may or may not know this but the HID lamps have many applications. These lamps are need in those locations or places that need very bright lights. Some of the examples of the places where the HID lamps are used are roadways, warehouses, sidewalks, parking lots, football fields, stadiums, etc. These lamps are also used in indoor gardening, houses, department stores, etc.

If xenon brenner ask any vehicle owners about HID lights, they will probably tell you what these lights are because many drivers are aware of the High Intensity Discharge lights. These lights are more or less like the natural day light and this is the main reason why many vehicle owners install these bulbs or lights in their cars. With the HID lights, it will be possible for the drivers to see the road clearly even when the area is dark.
