Another benefit to HID is the lower power consumption they require, typically 35 watts for HID, vs 55 watts for Halogen. This tech doesn’t come easy though, HID bulbs require not only a 12v input like Halogen, but also an ignitor and ballast system which are external components which require more space under the hood and sometimes require special mounting for both OE and Aftermarket applications. HID bulbs are filled with noble gas and contain special salts, when combined, create an electrical between the electrodes that glow extremely bright, much brighter than a halogen bulb. HID or ‘Xenon’ bulb emerged in the automotive industry starting in the early 1990’s, however HID (High Intensity Discharge) technology was invented and used long ago in industrial applications. Take a look at our latest Halogen bulb Recommendations based on our lab tests HID/ Xenon Out on the road and night and have visibility issues.ĬONS: Short Life, High Heat, Not as Bright, No option for colors (without sacrificing brightness), Dim over time Minimal amount of lighting you can get away with, and most people don’t thinkĪbout the lighting that goes into a vehicle during the purchase, until they get Governed regulations such as DOT in the US, ECE in Europe, and so on. To the low cost, many manufacturers choose halogen to meet the standards of the Halogen is the most widely used lighting tech, again due Halogen chemicals, with a filament coil, that heats up due to electrical They consist of a glass container or envelope filled with a mixture of Is cheapest, as the components are very simple compared to the others (HID and The automotive market, but also household, industrial, etc. Halogen bulb technology is the oldest around, but still very widely used not only in We’ll get into the details below and what you should look out for. When you change the bulb style out or even the intensity of the original bulb, it can change the beam pattern, sometimes in bad ways. Hella) to work perfectly with the headlight assembly or headlamp. Something to keep in mind is that all headlights, no matter reflector or projector, are specifically designed from the manufacturer’s vendor (ie. The two latter are the superior technology. The projector headlight style comes with all sorts of bulb types, including Halogen, LED, and HID. If you are buying a new vehicle where there is an optional ‘lighting package’ for an extra cost, typically it includes projector style headlights, and it’s worth the money when you start driving during the night, in inclement weather, at highway speeds, etc. Projector technology is a huge improvement over reflective tech., in that it not only produces an improved beam, but there is much less or non-existent ‘glare’, and the light goes a much further distance. Projector style headlights were created by Hella back around 1911, however the technology wasn’t widely used until 1989 on the Audi Quartz where it first appeared. You’ll see reflector headlights typically with halogen bulbs, but some come with special HID bulbs, and some even include built-in LED bulbs. The light output and beam depends heavily on the reflective portion and its design, and the newest style reflectors can achieve very good results with a nice cut-off beam pattern, in order to keep glare and dazzle away from oncoming drivers. Mirrors are strategically placed within the headlight to reflect light out onto the roads. A reflector headlight consists of a bulb installed into a plastic reflective bowl. Don’t let the date fool you though, as today, we still see most brand-new vehicles utilize the great technology. Reflectors were invented back around 1935, but I won’t get into the details there. There are two main types of headlight and foglight systems, reflector and projectors. Headlight & Fog Light Types Reflectors vs Projectors
