![]() ![]() In order to create light, the tungsten filament receives electricity from the car’s battery and heats up to around 2,500 degrees Celsius thus starting to glow (incandescence process). ![]() The reason? Halogen isn't exactly synonym to efficiency and, to better understand why, we'll explain how such a light bulb works.įirst of all, it is made of a glass envelope capable of resisting very high temperatures, plus a gas, usually a combination of argon and nitrogen, along with a tungsten filament. ![]() However, halogen bulbs are becoming the second option for more and more car companies around the world. Basically a halogen light bulb has a lifetime of about 1,000 hours under normal conditions, while replacement costs are usually very low comparable to the other types bellow (around 30 bucks for a decent set). HALOGEN HEADLAMPSHalogen headlights are currently the most popular in the automotive world and, in case you're wondering why does this happen, it's mostly because of their primaryĪdvantage: they're simple and cost effective. So, let's take one at a time and see what this is all about. Some of you will agree with our statements, others won't, but either way, each of the four types of headlamps has its very own pros and cons. We'll thus try to discuss the advantages and disadvantages of each of them, although people generally believe, and it sometimes happens to be true, that the newest is also the best. We won't talk about the headlamp history today because we already did that, but instead we'll try to focus on the four major headlamp configurations of today and see what they're up to. Laser headlights is an example, but before discussing them, we have to go through more common systems available for a larger use. Furthermore, researchers are continuously working on the whole "headlamp" idea, trying to find new breakthroughs that would obviously make their products better than the rivals'. The xenon bulb uses an entirely different system, which takes up more space than the halogen bulbs, and if the vehicle is not made for xenon lights, it may be an expensive or impossible process to convert.Although the whole automotive industry uses them, only a few people actually know how they evolved from simple acetylene lamps in the 1880s to very complex LED assemblies nowadays. This does not mean that a driver with halogen headlights can simply replace their bulbs with xenon versions to reap the benefits. No, the xenon bulb takes more space and uses a different system.īecause of the greater efficiency of xenon bulbs, they are being used more often in the construction of headlights. The color temperature of halogen bulbs is around 3,200 degrees Kelvin, resulting in a warmer, more yellowish light than xenon light.Ĭan you convert from halogen to xenon headlights? There is also some controversy as to how much better the xenon bulb's light is, if at all, and different bulbs will have different effects. While halogen bulbs do not have the lifespan or light intensity of xenon units, they are still much more common, and it is easier and less expensive to replace halogen bulbs. Color produced is a bright white light similar to natural daylight.Last 2 to 3 times longer than Halogen bulbs.The color temperature of xenon bulbs is around 4,500 degrees Kelvin, producing a bright, white light similar to natural daylight. Similar xenon bulbs also use less energy than a halogen equivalent. Though halogen is dependable, the bulb still uses a filament that will eventually burn out, while xenon bulbs use only gas and electricity, allowing them to last two or three times longer. ![]() They last much longer than the conventional halogen bulb and have a higher lumen output (brightness). Xenon HID lights are a more recent invention and offer several benefits over halogen. A ballast is used to ensure the right voltage is maintained inside the bulb. An electrical current is channeled through the gas in an arc, and the resulting reaction excites electrons in the xenon atoms, creating light. Xenon bulbs, or as they are more accurately called, Xenon High Intensity Discharge (HID) bulbs, forgo the filament and use only xenon gas. This allows halogen lights to maintain the same light intensity throughout their lives. The halogen interacts with the tungsten and helps replace lost particles while the light is turned off. Headlight filaments must be strong and are usually made of, or coated with, tungsten to give them durability. ![]()
