Drivers can often go years without needing to replace HID headlight bulbs, making them a convenient and worthwhile purchase option. The lifespan of your average halogen headlight bulb is just to 1, hours, while HIDs last between 2, and 3, hours. There are other headlight bulbs on the market that last longer than HIDs.
Xenon bulbs may last up to 10, hours, while LED headlight bulbs can last for up to 30, hours. However, every type of bulb will not work with every headlight installation or meet your unique needs as a driver so it is crucial to look at the pros and cons of each before you make a decision on which to buy. When asking how long do HID bulbs last, it is crucial to know that their lifespan is closely connected to how many times you power on the bulbs.
While the longevity of other types of bulbs may depend on running hours, HIDs depends on how often you use them. If you make frequent short trips at night, they are not likely to last as long. With so many options for headlight bulbs, truck lovers often wonder about the benefits of buying HIDs specifically. HID headlights produce more than 3, lumens which are more than twice as many lumens as traditional halogen headlight bulbs.
This makes the light from HID bulbs brighter and more efficient. The light from an HID headlight installation will reach further into the distance than halogen bulbs, will provide a greater scope of coverage in your peripherals, and provide even and focused illumination. HID headlights are said the be among the brightest lights on the market. They are also considered to have the whitest light and the best reach.
Additionally, HIDs have a better selection on the color spectrum. Halogen headlights are simply older-style incandescent lights -- the ones that use a filament to produce light -- with a more efficient twist in the form of halogen gas.
Their lifespan ranges from to 1, hours. Why such a wide range? Well, it's all about the heat which the halogen light produces in great quantities and efficiency which the system lacks. The halogen bulb is still an incandescent bulb, like the kind of light Edison invented, at its heart.
In any incandescent light electricity is forced through a tungsten filament. The filament resists the electricity and heats up. As heat and light are essentially the same thing from a physics standpoint, light is created. This is a very inefficient system, however. In an ordinary incandescent bulb, which has been largely phased out of the auto industry, the filament creates about 95 percent waste-heat and only five percent light.
And every time the tungsten heats up, a little of that metal is evaporated and the gas migrates to the inner surface of the bulb causing the typical mirrored surface of a dead bulb. Halogen headlight bulbs add a little bit of inert gas inside. This gas increases the amount of light created. It also allows the tungsten burned off the filament to migrate back, thereby increasing the longevity of the filament and the bulb.
Now, back to the heat issue. Say you have an incandescent bulb rated for hours at 12 volts. If you pushed In turn, more tungsten would evaporate and the bulb's life would be shortened, at least in theory. Cars often vary their voltage output and can range from 12 to 14 volts during one short trip. Additionally, let's say the bulb in question was in Alaska, where it's always dark and cold during the winter. LED headlights need extra heat sinks and fans to stay cooler, which can add to the price tag and make it difficult to fit an LED headlight into a traditional halogen headlight housing during installation.
But their cooler operating temperature makes them more eco-friendly and gives LED headlights the ability to run almost indefinitely. HID headlights are the brightest on the market, and the light they emit covers a larger area than halogen and LED bulbs. HIDs are also more effective at lighting up the sides of the road.
However, if not properly installed, HID headlights can reflect an intense amount of glare back onto oncoming drivers. Neither option will fit properly into the headlight housing unit for a traditional bulb.
As far as the size of the actual bulb is concerned, LEDs tend to be more compact while HIDs tend to be a little bit bulkier. One of the biggest draws for consumers when it comes to LED headlights is the fact that they can run for more than 20, hours. This means they will almost never need to be replaced. LEDs also have no small or moving parts that are breakable, making them a little more durable than HIDs.
