Halogen And Xenon Headlights-advantages And Disadvantages

Head lights are one of the most stylish parts of an automobile. Researchers all over the world are trying to make more advanced head lights that are brighter, whiter and efficient. Let us now take a look of the various types of head lights used in the automobile industry.

Halogen head lamps
One of the most popular head lambs are the halogen head lamps. It gives a tough fight to its competitors because of its long battery life. Basically a halogen lamp has a battery life of 1000 hours. But because of the lower efficiency halogen are not so favorites recently. A halogen light consists of a glass tube inside which has a mixture of argon and nitrogen and a tungsten filament. The glass envelope will be capable of resisting high temperatures. The main problem of using halogen head lamps is that when we use halogen headlamps huge amount of heat will be generated and thereby causing wastage of energy. There is one more problem when we are using a halogen head lamp. It is the way it reacts with various materials. The salt in skin oil can damage the glass bulb and it cannot resist very high temperature inside. Still halogen is one of the favorites of carmakers because it offers some unique advantages. Let us now take a look of these advantages

Halogen head lamps offers a very long batter life compared to others
They are available in different dimensions , so they will be compactable to various designs
They are very efficient
Halogen head lamps offer a high illumination so we will get a better sight by using these

Xenon head lamps
Xenon head lamps are another type of head lights that are used because of their better efficiency. Xenon head lamps consist of xenon gas and this gives a light blue shade as seen by the naked eye. Because of the amount of light the xenon head lamps generate and their color temperature. BMW 7 series was the first to introduce Xenon lamps in the year 1991.later many other car companies opted Xenon head lamps as their first choice because of advantages. The first advantage offered by xenon head lamps is that they are way more efficient than halogen head lamps. If saying the technical statistics a xenon bulb produces 3000 lumens and 90 mcd/m2, but in the case of a halogen light 1400 lumens and 30 mcd/m2 is produced. Let us now take a looks of some of the advantages and disadvantages of xenon head lamps.

Advantages
Xenon head lamps offers a longer lifetime than halogen head lamps
They are more efficient than halogen head lamps and utilizes less power too
The driver gets a better visibility by using the xenon head lamps

Disadvantages
High manufacturing cost
Because of the excess of glare it will be difficult for the driver
