Xenon lights are named such because of the xenon content in their fill gas. According to ArticlesM.com, xenon light bulbs employ xenon gas to increase the life of the bulb. Early incandescent light bulbs employed no fill gases and instead, featured a vacuum. Eventually, incandescent light bulbs began to feature argon or argon-nitrogen mixtures as their fill gas, which slows filament evaporation.
Overall, xenon light bulbs will last much longer than incandescent light bulbs. A typical xenon light bulb can last for anywhere between 8,000 and 20,000 hours. Incandescent light bulbs, on the other hand, are only rated to last for around 750 hours.
Both types of light bulbs have countless applications. They can be used both indoors and outdoors in most lighting fixtures. Xenon light bulbs are increasingly being featured as headlights in luxury automobiles.
Unlike fluorescent light bulbs, both incandescent and xenon light bulbs can easily be hooked up to dimmer switches. Utilizing dimming mechanisms with these light bulbs can increase the overall life of both types of light bulbs.
According to XenonLightShid.com, xenon lights are used as headlights because the whitish-blue light emitted by xenon lights produces clearer visibility.
