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 lights work in three steps: 1. Energy efficiency Compared to xenon headlights, halogen lights require less energy to start up, but more energy to keep going. They also generate large amounts of heat, which is wasted energy. As xenon lighting uses gas as its energy source, it needs less electricity to generate the light. Lifespan Xenon headlights last a lot longer than halogen ones — 2, to 2, hours for xenon headlights compared to to 1, for halogen.
Cost In general halogen lights are cheaper than xenon headlights to produce, purchase, install and repair. Colour The colour generated also differs.
Xenon headlights have a colour temperature of KK, which is a bright white-blue light similar to natural daylight and halogen headlights have a colour temperature of K, which is a warmer, yellow-white light. However, xenon headlights are less effective in foggy weather conditions compared to halogen lights.
Installation Installing halogen headlights is straightforward as they simply click into position. Xenon headlights require a ballast, which makes installation a little more complicated. You need mandatory light washer when installing xenon bulbs, as dirt on the light module might be dangerous for drivers coming from the opposite side.
Construction While both types of headlights are fairly robust, it is important to be careful when handling halogen lights. Touching a halogen light with your bare hands could put grease on the bulb, weakening it and resulting in it breaking. Additionally, as halogen headlights contain high pressure gas, it is a good idea to have some kind of shield in case they shelter. Some versions of xenon headlights contain toxic substances, such as metal mercury, which has a negative impact on our health if they break.
