![]() ![]() In this case, I’ve swapped one of the halogen bulbs for a LED bulb. From the factory, it’s equipped with HID low beams and halogen high beams. This example uses the headlights of an Infiniti G35. ![]() Top-shelf xenon HID bulbs are known to last for the life of the car, while xenon gas bulbs only have a 6-month life span.The image above demonstrates a clear advantage of LED headlight bulbs. A tungsten filament serves as the lighting element in a xenon bulb. Tungsten electrodes are the lighting elements in a xenon HID bulb that produce a very bright, ice blue/white light. On the other hand, xenon gas-filled bulbs are basically halogen lamps made to imitate a xenon HID bulb. So what’s the difference between a xenon HID lamp and a xenon gas-filled lamp? Xenon HID lamps are electric gas-discharge lamps that contain xenon, a noble gas which ignites when applied with high pressure. You’ll know you’re looking at a xenon gas bulb if its product code starts with the letter “D.” HID vs Xenon Keep an eye out for the product code on the box or around the fitting of the bulb. While xenon gas does enhance brightness, it is still not at par with HID lamps. These halogen bulbs still use a tungsten filament as their lighting element. While a xenon lamp does contain a certain amount of the noble gas, it does not operate on the same technology HID bulbs do. It is designed to emulate a xenon HID bulb in terms of light production and performance. Xenon gas-filled headlightsĪ xenon gas-filled bulb is simply a halogen bulb that contains xenon instead of halogen. ![]() Thus, the life of a xenon HID lamp can be extended by not a turning it on if it has just been turned off. There is also a large amount of pressure involved in operating a bulb like this, thus it can pose a safety hazard if its enclosure is compromised.Ī xenon HID lamp wears out faster when it gets turned on and off frequently, and not because of how long it is used. High voltages are needed to activate a Xenon HID bulb. They have replaced taxi and landing lights on airplanes. Xenon HID bulbs are used in vehicle headlights which are known to last for the life of the car. HID lamps of this variety are often used in movie projectors, stadiums, and parks. They produce light that closely mimics the intensity of sunlight. Xenon HID lamps are several times brighter than ordinary halogen lamps. This plasma intensifies the light created by the arc while reducing its power requirement. Once started, metal salts in the arc tube heat up and evaporate to become plasma. This transparent tube contains the xenon gas which kickstarts the arc’s initial strike when high voltage is applied. An electric arc is created between the tungsten electrodes contained in an arc tube, which is the light-producing element. It produces light primarily with the help of the noble gas xenon and metal salts. D2S) Street legal even if color temperature exceeds 4300 Kelvin Not street legal if color temperature exceeds 4300 Kelvin Definitions Xenon HID headlights on an AudiĪ Xenon HID lamp (high-intensity discharge) is an electrical gas-discharge lamp. H11) Fitting label with the letter “D” (e.g. HID Xenon Uses tungsten electrodes as its lighting element Uses a tungsten filament as its lighting element Genuine bulbs cost over $100 per bulb Price ranges from $5 to $40 or sometimes higher Fitting label with the letter “H” at (e.g.
