Hybrid power is the way forward if the car industry is to be believed so we've found the top 10 best hybrid cars to buy now Record demand for cars amid new and used supply shortages persuades buyers to abandon favourite brands. Skip to Header Skip to Content. Traditional halogen lamps emit light by passing a current through a filament and creating huge electrical resistance. Whereas, light in a xenon unit is produced by an electrical arc, basically just think of it as an electric current, which jumps from one contact to another whilst immersed in a gas - in this instance xenon.
The xenon gas amplifies the brightness of the light, which helps it quickly reach the temperature required to emit a high-intensity beam. Aside from illuminating more of the road ahead, xenon headlights also have a greater lifespan than halogen units. Due to the high intensity of xenon headlights, they can dazzle other drivers. Car manufacturers have resolved this by using self-levelling systems to prevent the beam from pointing too high. Mail this article Print this article.

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.
