The Differences Between LED, HID And Halogen Headlights

The Differences Between LED, HID And Halogen Headlights. porsche

A few years ago, people where a lot more interested in the color, model and design of their car, while none or very little on the actual headlights on the automobile. Headlights were once very common, and for this reason not much attention was given to them unless they required a replacement or they happened to break down.

Today with the latest technology advancements, cars now light up the roads a lot brighter. Due to the developments of longer lasting, brighter and better headlights, today more and more car owners are now deciding between LED, HID (Xenon) and Halogen headlights. Here is more information on the differences between each.

1. Halogen

Halogen lights are the more common headlight used on the majority of cars. This particular invention dates as far back as the 1960s, which was once the solution to generate light using limited resources. Similar to incandescent lights, the halogens use a tungsten filament that is heated in order to create light. However, the filaments on these bulbs are encased inside a protected halogen gas bubble, which improved the performance and longevity of the bulbs.

These lights were simple to manufacture which made manufacturing processes inexpensive. In addition, the replacement costs of these bulbs are relatively low. The halogen headlights fit most car models and are available in various shapes and sizes. On the other hand the halogen lights are unable to provide visibility like the LEDs and white HID bulbs are able to produce. Significant amounts of heat are lost when using these headlights, which translates into wasted energy. These lights are also fragile which means they require additional care, unlike the HID and LEDs.

2. HID- High Intensity Discharge

These bulbs are better known for bright light emissions that are able to reach far. The tungsten in these bulbs are encased into quartz tubes which contain a xenon gas. These bulbs usually use a bit more power as they are turned on, yet they use a lot less power in order to maintain their brightness. These headlights offer a lifespan that is much longer when compared to halogen headlights. This might appear to be the better choice, but they come with their own limitations in regards to the expense involved in manufacturing processes and replacements. These bulbs are more complex to manufacture due to their complex design. Their brightness can also result in an effect that is blinding for oncoming traffic, which can result in a danger on the road.

3. LED- Light Emitting Diode  

The LED headlights are the most recent and current innovation that takes over from Halogens and HID. LEDs employ a diodes technology which means they produce  light when the electric currents are exciting their electrons. These bulbs require a low energy and power, yet still produce a light that is brighter when compared to the halogen headlights. The diodes are easy to manipulate and change into a number of shapes which results in unique configurations. When it comes to LED technology, the drivers vision become more focused and improved. Even though initial costs involved in halogen and HID bulbs are far less in comparison to the LEDs, maintenance and operational costs of the LEDs is far lower. They also offer the longest life span out of the three. LEDs use a lot less energy, which means the overall costs of LED systems are usually much lower than the conventional types of lighting systems.

Which Headlights Shine The Best?

According to motoring experts, you will notice a number of stand out difference in association to the light that is produced by halogen, xenon and LED headlights. The LEDs offer a color temperature that is the coolest at about 6,000 Kelvin, which means they appear whiter than actual daylight. The HID bulbs offer around 4,500 K, while halogens offer a yellowish light of around 3,200 K.

When comparing reflection, the LEDs provide the best light return when it comes to road signs. The xenon lights offer better illumination for sides of a road. Both the HID and LEDs offer large light patterns on the surface of the road, while halogens provide smaller pools of a yellow light that shine directly to the front of the car.

The Halogen Headlights

The halogen headlights at this stage are still very common and found in the majority of consumer cars. This bulb type are very similar to incandescent bulbs that use heated filaments made out of tungsten in order to produce a light source. The halogen lights produce a lot of heat, while even the smallest deposits of moisture from the skin on a bulb during the process of replacement can have an affect on their overall performance. The stand out advantages of the halogen headlights is their longevity and cheap replacement costs.

The HID (Xenon) Headlights

The HID headlights from Diodedynamics.com which stands for High Intensity Discharge, produce a much brighter light when compared to the halogen bulbs, and use a lot less heat. However, the white-blue light that the xenon bulbs produce is often very bright that it can blind oncoming traffic and drivers on the road. This bulb does require more power to start up, but once operational they use a lot less energy in order to maintain their consistent brightness. These bulbs offer a long-lifespan while emitting very little heat. They cost more when compared to the halogen headlights.

The LED Headlights

The more recent innovation when it comes to headlight technology, the LEDs use small diodes instead of filaments and gas to produce their light source. This occurs when the electric currents are exciting their electrons. They require very little power in order to operate, yet they do produce heat levels that are significant on their diodes. This usually means a heat control system is required close to other components of the car and on the bottom part of each headlight. The LEDs are small in size and can be transformed into all types of shapes. The light they produce is directional in comparison to diffused, which makes them the ideal choice when it comes to headlights.
