The reason is the low energy efficiency behind these bulbs. Do you want to know about the best bulb that produces great light at a low energy cost?

Yes, such bulbs are available in the market at affordable prices. These bulbs can be seen in modern lighting and are known as halogen bulbs. You may have a question: what are halogen bulbs and how many types of them are available in the market?

We will answer every question related to this modern bulb in this post. Let’s dive in to learn everything about halogen bulbs in detail.

What Is A Halogen Bulb?

Whenever we hear about the bulb, the first thing that comes to mind is Thomas Alva Edison. The man who invented the first bulb. Do you know what type of the bulb was invented by him? That bulb was incandescent and has been the lighting source for decades. This bulb has been replaced with halogen and is widely used in lamps and other lighting sources. 

A halogen light bulb contains a filament of tungsten sealed in a transparent coating. It is also known as quartz halogen and contains a mixture of inert gas. The inner gas also contains a small amount of halogen from bromine and iodine. When the inert gas and halogen combine, it produces a chemical reaction. The halogen cycle helps the tungsten filament to operate at a higher temperature. This light bulb is used daily and comes at an affordable price.

History Of Halogen Bulbs

There is a long history behind the halogen light bulb. It is an advancement of the Incandescent bulb invented by Emmet Wiley and Elmer Fridrich in 1955. One major reason behind it is to protect the darkening of the bulb envelope. The halogen filament used the chlorine that was patented back in 1882. 

After that, iodine was used to improve the efficiency of tungsten deposition back into the filament. Then in 1959, two workers of general electric named Emmet Wiley and Elmer Fridrich patented the first-ever halogen light bulb. The presence of the halogen in the inner tungsten keeps the bulb clean and produces constant output.

Components Of Halogen Light Bulb

Like any other bulb, halogen also contains the basic components. It consists of the base, filament, and glass envelope. Each component has its role in protecting the chemical composition.  Following are the various components of the halogen light bulb:


The process makes the filament drawing tungsten with a binder-like material. It is kept under high pressure to turn into a fine wire. The shape taken after the binder process is of the orifice. After that, the coiled wire is attached to a lead wire that is spot welded later. The final filament wire comes under the “CC” type when it is coiled again.


The base of the halogen bulb is manufactured by using molds. A hollow-shaped screw is also used in the base so that it can easily fit into a light socket. There are various halogen lamp bulb bases, including the 2-pin, 6-inch flexible leads, 1-inch ribbon leads, and 2-pin connector base. Each of the bases has its use in terms of the stability of the upper structure.

Glass Envelope

The glass envelope is the third and most important component of a halogen bulb. It is a shield and promotes the halogen cycle of inert gas. The bulb’s envelope also protects the electrodes from leaving the lighting device. Moreover, it also promotes the chemical resistance process with an enclosure and external temperature. The invention of the halogen light bulb is to stop the darkening of the glass envelope. The quality of the bulb’s envelope is also responsible for its working process.

What Are The Uses Of A Halogen Bulb?

Today, halogen lamp bulbs are widely used in homes and industries. As it is more energy efficient, various lamps have this bulb to provide good lighting intensity.

Commercial Uses

These bulbs have a large commercial use in various industries. One of the major benefits of halogen bulbs is that they offer good light when the space is limited. You can see halogen lamps in retail stores, museums, tracking ways, vehicle headlights, and many more. The large PAR bulb of halogen is used in security lights, high ceilings, and landscape lights. It has a larger wavelength and provides clarity at night.

Residential Uses

Halogen bulbs have a huge application as a daily lighting source. These bulbs are widely used as modern halogen lamps to decorate the home space. Its usage is in the working area that requires more high-intensity light. The halogen light bulb is ideal for the kitchen, living area, outdoor sitting area, and entrance.

Other Uses

Halogen lamp bulbs have other uses as flood lights. During infrared spectroscopy, these bulbs are also used as a lighting source. Moreover, it also has uses in inspection lights, illuminators, and lizard monitor keepers. 

How Is A Halogen Bulb Different From An Incandescent Bulb?

The majority of people have confusion between halogen and incandescent bulbs. Both of the bulbs look similar and work almost the same way. But there are a few differences that make halogen bulbs more convenient. Here are the key differences between these lighting bulbs:

Halogen Bulb

Incandescent Bulb

The Halogen bulb has inert gas called halogen. When the bulb is turned on, iodine and bromine make bonds with vaporizing tungsten.

The Incandescent bulb has deposited vaporized tungsten inside it. Its filament is thin and takes charge during the working process.

These bulbs have a lifespan of 2,250 to 3,500 hours.

These bulbs have a lifespan of 750 to 1,000 hours.

It is more energy efficient.

It is less energy efficient.

Halogen bulbs produce more visible light. It has a luminous efficacy of 16 to 24 (lm/W).

Incandescent bulbs produce less visible light. It has a luminous efficacy of 12.5 to 17.5 (lm/W).

It produces a blue-white tone light that is ideal for working space.

It produces a yellowish tone light that puts more stress on the eyes.

What Are The Different Types Of Halogen Bulbs?

There are various types of halogen lamp bulbs available in the market. Usually, these bulbs select after looking at their base. Before you start selecting a halogen bulb, let’s take a look at its types.

Arbitrary Halogen Bulb

One of the most popular bulbs is the A19 Halogen bulb. It is designed in A-shape that allows it to produce higher output. The majority of the standard bulbs are also coming in arbitrary shapes. That’s why halogen bulbs are commonly used to replace traditional lighting bulbs. You can use these bulbs anywhere in your home.

PAR Halogen Bulb

Parabolic Aluminized Reflector(PAR) bulbs are used in areas that require precise lighting. This halogen bulb uses an electric arc to produce light. Due to it, these bulbs have the edge over the other halogen light bulbs. It comes in different sizes, of which the most common are PAR14, PAR16, and PAR20. You can use these bulbs as floodlights, desk lamps, recessed, and accent lighting.

T-Type Halogen Bulb

It is a tubular-shaped halogen bulb used as a desk lamp, pendant light, floor torchiere light, etc. These lamps are less likely to be overheated or burst at higher temperatures. The diameter of these bulbs is smaller than the incandescent, which makes them suitable for different areas. Various industries use the T-type of halogen light bulb to facilitate their operations.

MR16 Bulb

The Multifaceted Reflector(MR) uses an advanced mechanism to provide a large light intensity. MR16 is the most common halogen bulb used for recessed lighting purposes. These bulbs highlight the particular area used for track, under-cabinet, and landscape lighting. Some other uses of this halogen bulb are floodlights and pillar lights.

Double-Ended Halogen Bulb

As the name suggests, this halogen bulb can produce light from both ends. It is also known as the J-type which looks similar to CFLs. These double-ended bulbs instantly generate light, unlike CFL, which takes longer to warm up and work. The J-type bulb is the lighting source for bathrooms, table lamps, and ceilings.

How Does A Halogen Lamp Bulb Work?

The working of the halogen light bulb is based on the mechanism of thermal radiation. During the process, light produces when the solid tungsten is heated at a high temperature. The halogen gas inside the glass envelope reacts with the tungsten filament whenever you turn on the switch. In the reaction, tungsten starts to evaporate and starts covering the filament. 

Additionally, some amount of the tungsten returned to the filament that extends the bulb’s life span. The process protects the tungsten from attaching to the glass of the bulb. The total temperature required is higher, which is only achieved by quartz. Each halogen lamp bulb is manufactured by using a pure quartz capsule filled with halogen gas.

After that, the current flow starts to flow in the cycle, which makes the particles redeposited back onto the filament. That’s why these bulbs have a high luminous efficacy of 25,000 hours.

Advantages And Disadvantages Of Halogen Light Bulb
