Why are xenon headlamp bulbs better than tungsten halogen headlamp bulbs?

"Xenon" is a widely-used word in the marketing of headlight bulbs. The only headlamp bulbs that can legitimately be called "Xenon" are high-intensity discharge ("HID") bulbs for use in headlamps designed to accept them. Instead of a filament, they have a pair of electrodes separated by a gap. An electrical ballast steps up the vehicle's 14-volt line power to several thousand volts to jump the gap, and that arc is the light source in an HID headlamp. Halogen bulbs don't have this. Instead, they have a coiled filament made out of tungsten wire, which glows white-hot when the vehicle's 14-volt power is applied to it.
"Xenon" is also used in the marketing of halogen headlight bulbs. Most halogen bulbs do have some proportion of Xenon in their mix of fill gases; a higher proportion of Xenon can improve operating characteristics of the halogen bulb (longer lifespan, higher luminance). But that "Xenon" word is often fraudulent, especially when it is used to sell bulbs that have a blue or purple tint to the glass. Such bulbs (badly) imitate the color of HID headlamps, but they significantly reduce the headlights' performance because the colored glass blocks a lot of light that would reach the road if the glass were colorless.

How much energy does a tungsten halogen bulb use?
Halogen bulbs come in various ratings, as do all bulbs.
How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
What are the benefits of using halogen bulbs?
"Halogen bulbs have a longer life and better illumination than incandescent bulbs. They are compact in size, and dimmable unlike flourescent bulbs. Halogen IR (infrared) bulbs use less electricity, also."
How do you change a headlamp on a GMC Envoy?
On a 2004 envoy, open the hood and on the top of the headlight assy there are two tabs that you pull up allowing you to pull the headlamp assy forward and access the the bulbs. These are halogen bulbs so remember to wear gloves when handling the bulbs.
What is the difference between normal headlamp and xenon headlamp?
A "normal" (halogen) headlamp uses a bulb that contains a coil of tungsten wire called a filament inside a small, thick glass or quartz capsule. The space within the capsule is filled with a mix of gases including some iodine or bromine compounds known generally as halogens. When the power is switched on, it flows through the tungsten wire, which heats up white-hot and that's your light source for the headlamp. An HID (high-intensity discharge, "xenon") headlamp does not have a filament inside the capsule. Instead, it has a pair of electrodes separated by a gap (similar to a spark plug). The capsule is filled with Xenon gas and metal salts. When the power is switched on, it goes to an electrical ballast which steps up the vehicle's 14-volt line current to several thousand volts to jump the gap between the electrodes. This starts an arc, which heats up and vaporizes the metal salts, which then make the arc glow much brighter, and that's the light source for the headlamp. Only headlamps designed and built as HID headlamps can safely and effectively use HID bulbs. Halogen headlamps must use halogen bulbs. "HID kits" are widely available, but they are (all) illegal and dangerous. Some halogen bulbs are promoted using the word "xenon". All halogen bulbs contain xenon gas as an ingredient in the fill gas mix. To a certain extent, increasing the proportion of xenon permits the filament to burn brighter without shortening its lifespan. But "xenon" is also used (falsely) to promote bulbs that have blue glass instead of clear glass. These blue-glass bulbs imitate the color, but not the output or performance, of real HID headlamps.
Which element is used in light bulbs as the filament?
Generally, tungsten.
Can you use halogen in older cars for headlight bulbs?
Almost all cars made in the last 30 to 40 years will use halogen car bulbs. If you have a vehicle older than this, the chances are you will not be using a standard bulb size that is easily available anyway. In this case, the easiest option is to replace the bulb holder with ones that will fit into the headlamp housing - you may need to modify the housing and cabling to suit. The other option is a complete replacement headlamp unit, which mat be available as an aftermarket upgrade, especially for more popular classic cars. Lastly, if standard halogen bulbs are not bright enough, have a look at premium halogen/xenon based filament bulbs like Ring Xenon Max, or upgrade to full HID lighting with an upgrade kit.
Which produces more lumens 1-250watt Halogen or 2-39W T5 Fluorescent bulbs?
250W tungsten halogen gives around 10,000 lumen. 2 x 39W T5 fluorescents gives a total of between 4,000 to 6,000 lumen.
How does a xenon bulb compare to halogen?
Xenon bulbs give off whiter light than Halogen bulbs, which give off a more yellow tint. Also, Halogen bulbs give off more heat than Xenon bulbs.
What element is found in cheaper light bulbs?
Fluorescent tubes create ultraviolet light when electricity is passed through mercury vapor. The UV light causes the phosphors, dusted over the inside of the tube, to fluoresce--or give off visible light. Three of the elements found in the tube would be: Phosphorous, mercury, and tungsten.
What is in filament of light bulbs?
tungsten
What is the difference between halogen and incandescent bulbs?
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
