Are you considering upgrading your car headlights? Halogen light bulbs are an efficient and budget-friendly option. If you think halogen bulbs are outdated, we will clear the misconceptions. You can also compare them with other lighting options. Buckle up, this blog covers everything on halogen headlight bulbs!
What Is a Halogen Light Bulb?
Can you recall an old yellow bulb from any heritage building? It must be a halogen bulb, a basic incandescent light that illuminates with the burning of a tungsten filament. The filament is sealed inside a glass container filled with a mixture of halogen (a group of chemicals like iodine or bromine in the periodic table) and inert gas.
Electrical power heats up the tungsten filament to high temperatures. It gives off a bright white light for illumination. The halogen inside the glass container acts as a recycling agent; the halogen atom combines with tungsten vapor and redeposits it on the filament. With this cycle, the filament lasts longer and doesn’t burn completely.
Halogen also keeps the glass container clear, preventing the disposition of clouds on the glass walls. The name “halogen bulb” is because halogen is an integral part of the bulb. To your surprise, halogen bulbs have been used for automotive lighting since the 1960s. They’re still a preferred option due to cost-effectiveness, weather resistance, and good visibility.
How Halogen Light Bulbs Work
Halogen light bulbs work on the incandescence principle and halogen cycle. When electricity passes through a tungsten filament inside a gas-filled glass container, it heats up to 4500°C and emits a bright white light upon burning, known as incandescent. The brightness level depends on different factors like wattage, filament position, thickness, and temperature level.
Once the filament is heated, a recurring halogen cycle starts. The glass container of the bulb is filled with halogen (elemental fluorine, bromine, iodine, chlorine gas, etc) and inert gas. As the filament heats up, the tungsten is consumed and vaporized. The halogen triggers a chemical reaction and bonds with tungsten vapors. These vapors are re-deposited on the filament to keep it from being consumed to heat.
Every time you turn on the halogen bulb, the cycle repeats. It allows the bulb to operate at higher temperatures, which means more brightness, and it lasts longer. The halogen gas inside the glass container also prevents the clouding effect that’s common in other incandescent bulbs. It addresses the clarity concern and makes halogen bulbs ideal for car headlights.
Benefits of Halogen Light Bulbs for Cars
Halogen headlight bulbs are commonly used lighting solutions for cars. Here are the key benefits that make them a preferred choice for cars:
Affordability
Halogen headlight bulbs are mass-produced around the world, which makes them highly affordable. Before the advent of LED and HID headlights, halogen bulbs were most used for car lighting. These headlights come at a fraction of the cost of other lighting options. You don’t need to install any additional equipment like heat sinks or ballasts when using halogen headlights.
Availability
Halogen light car bulbs are compatible with most cars. You can use them with 12V and 24V electrical systems without a worry. You’ll get efficient halogen headlights for every car model. Unlike HIDs, you will not have to go on a serious market hunt; they’re readily available at all stores. Moreover, halogen headlamps are road-legal and DOT-compliant.
Performance
Most people think that halogen light car bulbs underperform, but that’s not the case. These bulbs are highly efficient and offer up to 1600 lumens of brightness. The clarity and weather resistance are also next level. You can use them with reflectors and projector casings. Halogen headlamps are the best option for winter as they prevent ice buildup due to the heating effect.
Types of Halogen Light Bulbs
There are a variety of halogen light bulb types available in the market. Each type has unique features and offers a plethora of benefits. Let’s explore to help you find the best type as per your needs:
Standard Halogen Bulbs
Standard halogen bulbs are commonly used for residential lighting. They don’t have any special features but work with great efficiency. You can identify standard halogen bulbs with their arbitrary cylindrical shape.
Dimmable Halogen Bulbs
Dimmable halogen bulbs come with a brightness adjustment option with a dimmer switch. You can adjust the brightness to different levels according to your requirements. The working principle of dimmable bulbs is the same as standard halogen bulbs.
Infrared Halogen Bulbs
Infrared halogen bulbs are not designed for illumination but to offer a soothing heat effect. They are used in infrared heaters placed in incubation compartments or heat lamps used in massage and physiotherapy centers.
Other Headlight Types & Halogen Bulb Applications
Apart from halogen bulbs, there are various other headlight options. Let’s explore their properties and applications. We will also compare all the types in the subsequent section:
LED (Light Emitting Diode) Headlights
LEDs have become a popular option for car headlights. Whenever electrical current flows through an LED, it produces visible light. LEDs are highly efficient and long-lasting. The light output is bright and clear. Most modern car models come with LED headlights.
HID (High Intensity Discharge) Headlights
HIDs produce extremely bright light and work on the gas-discharge principle. There are strict regulations on HIDs because they usually produce light above 6000 Kelvins that appear as a bluish light. However, road-legal HIDs are efficient and durable.
Matrix Headlights
Matrix headlights are basically LED headlights connected with a radar system that helps generate an adaptive beam. It helps avoid blinding of oncoming traffic and is considered an advanced safety feature. The US laws are adapting to this new technology.
Other Applications
Halogen bulbs have a variety of applications in industrial lighting, outdoor lighting, task lighting, and commercial lighting. Halogen bulbs are easy to replace and very cheap. The color temperatures achieved from halogen bulbs are ideal for these applications.
