How do xenon headlights work? A xenon lightbulb works in three steps: Ignition. A high voltage pulse is used to create a spark inside the lightbulb. This ionizes the xenon gas and creates a tunnel of current between the tungsten electrodes. Initial heating. The arc is operated at high power and the temperature within the capsule rises quickly. The resistance between the electrodes drops.
At which point the ballast registers the reduced resistance and switches to continuous operation. Continuous operation. The arc has now attained its stable shape and the produced light has attained its nominal value. The ballast now supplies stable electrical power so the arc will not flicker.
Light output Xenon headlights are more than twice as bright as halogen ones — lumens compared to lumens — which is why xenon headlights illuminate more of the road than halogen ones.
However, halogen headlights are more effective in foggy weather conditions. Halogen headlights use less energy than xenon to start-up, but they require more energy to keep going. Xenon headlights use gas as its energy source, so less electricity is needed.
Cost Halogen are the clear winner here. Colour Xenon headlights have a light blue colour K , which is similar to natural daylight, and halogen headlights are a yellow-orange colour K , which is warmer.
Installation Installing halogen headlights is straightforward — they just click into position. Installing xenon headlights is a little more complicated as you need both a ballast and a mandatory light washer. Halogen bulbs can be weakened by grease from your bare hands, which can result in it breaking. Additionally, some xenon headlights contain toxic substances, such as metal mercury, which has a negative impact on human health if they break.
The xenon bulb is a kind of high intensity discharge lamp containing the noble gas Xenon in the major proportion.
The gas inside them gets ignited when a high voltage is applied across them and an arc is produced across the electrodes. The light in the Xenon filled lamps is produced by striking an arc between the two electrodes. These lamps require a starter for the ignition to be quick, there is also a need for electronic ballast for their proper functioning.
The light produced by these lamps is almost natural and has a cool radiance as compared to the warmer lights. The light produced by the Xenon filled bulb is almost similar to the daylight or to the natural sunlight.
Also, the intensity of their light is twice that of the conventional lamps. High Intensity Discharge lamps are efficient at producing light and give a brighter light for the given power rating. These lights are consistent in case of varied temperatures and therefore are more suitable for outdoor applications. They have a lower pressure which is in contrast to the Xenon lamps. These lights are also cost-effective. The advantages of the Xenon lights is that they give higher intensity light with less power, the light produced is somewhat natural, the color of the light makes the signboard and marking easily visible during the night hours, when the visibility is less due to weather conditions it provides road safety, it is eco-friendly in many ways.
Some of the disadvantages of high intensity discharge lamps are- they cause a problem for the front drivers due to their high beam on the rearview mirror which may lead to accidents, in some cases, they are less efficient in poor weather conditions. One of the major drawbacks of these lamps includes that they have high pressure in them which may be at times explosive.
Another drawback of it is that they are expensive. Now I can be comfortable with an HID upgrade in my replacement car. I was angry and sad simultaneously. Name required. Email required.

HID High Intensity Discharge, or HID lamps, are a type of light fixture that offer several advantages compared to the traditional incandescent, or fluorescent lamps. Summary: 1. Xenon lamps do not need to warm-up like other HID lights.
