The beginning of any sort of invention started with fire. Fire not only protected the cavemen from harm's way, but it also lit the path for them. But of course, mankind did not stop with fire.
They invented newer, more sophisticated ways of bringing light to their life, and today we have a variety of light source to choose from.
Starting from the smallest spot LED lights to giant stadium light, two things are common. They are the structure of the bulbs and the mechanism on which they work. The source of light has wires, a covering, and some form of a chemical substance that aids in creating the light energy.
Halogen bulbs are one form of tube lights that use gas and metal materials to create light energy. Question is what kind of halogen bulb is more suitable for you?
What Is A Halogen Bulb?
The chemistry behind the light bulb is simple: a gas burns in the presence of a metal filament that produces an excessive amount of heat, and this creates light energy. However, the process is not that simple. Not every gaseous substance has the same bonding energy as an inert gas.
Thus, more reactive gasses tend to burn the metal filaments quicker than an inert gas. However, halogen gas, in particular, has some special qualities. It can prevent the blackening of the tungsten filament which is generally used in light bulbs. Moreover, halogen gas reduces the rate at which the tungsten filament burns.
Being an inert gas means halogen gas requires more heat to evaporate. As a result, the tungsten burns with more energy to form a bond with the inert gas. This burning creates immense heat and also light energy as a by-product.
To contain the heat and light energy, a glass mold of superior heat-resistant factor is used. It dissipates the heat produced inside the bulb and protects the outside environment from getting heated.
Why Use Halogen Bulbs?
A current issue everyone is worried about is natural resources, which includes metals, gas, water, air. Without these constituents, it will be impossible for mankind to live and thrive.
So, nowadays, manufacturers and innovators are trying to look for ways they can make their product more efficient and energy conserving. In the light production realm, halogen light bulbs are one of the most efficient bulbs.
Because of using an inert gas, the bulb manages to produce light for a longer period of time by minimizing the rate at which the metal filament burns. The light energy created through evaporation of halogen is also much brighter as halogen requires more energy to burn.
This increases the efficiency of the bulb by 10 to 20 percent. This means, the light bulbs will not have to be replaced at a constant rate and will decrease the cost of energy as well.
In addition to that, halogen bulbs also produce pure white light. Many problems created due to dimmed and faulty light can be avoided using halogen bulbs. The pure white light is also suitable as display lights and can be used for photography, painting, and in many other fields.
Also, the vibrant light brings out the color of the object more vividly. Thus, it helps in creating a better portrait. However, halogen bulbs are costly compared to its peers.
Types Of Halogen Light Bulbs
While the process of all the halogen light bulb is the same, it has a collection of different bases, lamps, and filaments. Depending on the type and need, the bulbs can be of a different style.
However, one of the most common types of a halogen bulb is the J-type and T-type bulbs. With minute differences, the two bulbs serve a different purpose.
T-Type Halogen Bulb
Among the most common form of halogen light bulbs, T-type wins. It is named T-type after its shape, which is tubular in form. Even though standard halogen bulbs are cylindrical, the tubular form of the bulb adds certain benefits to the T-type halogen bulb.
The filament inside the tubular bulb burns in the presence of halogen. However, some of the tungsten particles return back to the filament, increasing its life expectancy. The tungsten filament is also twisted and attached to the base.
This helps in including a wide filament in a smaller space inside the bulb. The diameter of the glass in the T-type bulb is 1/8 inch, which protects the glass from overheating and bursting. T-shaped halogen bulbs are usually used for indicator lights, automobile emergency signal lights, aircraft, and in instruments.
J-Type Halogen Bulb
Among the more peculiar forms of halogen bulbs, there is the J-type. Aside from its peculiarity in structure, this specific bulb is quite handy for a number of reasons.
The J-type halogen bulb requires a special base, customized for the filament. Here, the base of the bulb is recessed and requires a signal contact. The base is small and narrow, about 3/8 inch. One interesting thing about this model, in particular, is the shape is that it is double-ended.
It means the bulb will generate light at both ends and work as a 188 mm long tube light. These bulbs are perfect for household use as the voltage requirement is 120V. Both ends of this bulb produce 300 watts of pure white light which can be used for bathroom fixtures, table lamps, ceiling and for security purposes.
J-Type Vs. T-Type
It really comes to personal preference when it comes to these two options. Both are halogen bulbs, and both produce pure white light. While the T-type is tubular and can act as a single unit, the J-type is double-ended and produces 300-watt power.
T-type is more suitable as indicator lights and can endure for a longer period while J-type can be used for household utensils.
Among the many sources, halogen bulbs are the closest form of an incandescent light. So, if you are looking for similar results but want to save more energy, then consider halogen bulbs.
Both J-type and T-type will beget similar outcome, but in the end, you get to conserve energy and save money.
