Halogen bulbs are the modern form of old incandescent bulbs. They work on a similar principle but with the addition of the halogen cycle. Let's learn about halogen lights, their working principle, pros & cons, and whether they are safe or not. We will also explain how you can safely use them at your place. Part 1: What Is A Halogen Bulb? A halogen bulb is an advanced form of traditional incandescent bulbs. This bulb contains two main things: a filament and halogen gas inside it. The filament (a thin wire) glows and produces bright light when electricity passes through it, and the halogen gas (bromine or iodine) keeps the bulb glass and clear filament lasting longer. The combination of these two components causes the bulb to light at its full capacity instantly after turning the bulb ON. The light from this bulb is very natural and similar to daylight, which clarifies minute details and colors. This is the reason these bulbs are commonly used in car headlights, task lights, spotlights, and desk lamps. Despite their small size, they produce more light than traditional bulbs and can easily be used in modern lighting fixtures. However, this should be handled very carefully and kept away from flammable items because they get very hot instantly after turning the electricity ON. Part 2: How Do Halogen Bulbs Work? Halogen bulbs work on the principle of incandescent bulbs with one primary exception of the Halogen Cycle. This cycle makes the halogen bulbs more efficient and keeps them bright for a long time. The process begins when electricity passes through the thin tungsten filament located at the center of the bulb. The tungsten filament resists the electric flow, starts burning, and produces heat. This heat made the filament glow and ultimately produce light, which you see. During the burning of the filament, some tiny bits of the tungsten wire (filament) get broken off slowly. The halogen gas inside the bulb picks up these tiny bits and carries them back to the filament. This process continuously repeats inside the bulb, which we call the halogen cycle. This cycle does not let the filament wear out quickly and stick to the glass, hence keeps the glass clear and the light brighter for a long period. Part 3: Halogen Light Bulbs Types & Shapes 1: Standard Halogen Bulb: Standard halogen bulbs are similar to the traditional incandescent bulbs. They are commonly used in ceiling fixtures and lamps for general lighting purposes. 2: PAR Halogen Bulbs: Parabolic Aluminized Reflectors (PAR) bulbs produce a high directional beam of bright light. It is commonly used for transportation, residential, and commercial lighting. 3: MR Halogen Bulbs: Multifaceted Reflector (MR) halogen bulbs have a reflecting coating inside which directs the light in the form of a focused beam. They are good for directional lighting purposes. 4: Infrared (IR) Halogen Bulbs: Infrared (IR) halogen bulbs are more energy-efficient and come with an infrared coating inside the bulbs to reflect the heat. 5: HPL Halogen Bulbs: High Performance Lamps (HPL) halogen bulbs come with a tube-shaped compact design. This compact bulb is ideal for professional stage, film, and theatrical lighting. 6: Bi-Pin Halogen Bulbs: Bi-pin halogen bulbs do not have a screw cap; instead, they have two thin metal pins to plug into the matching socket. This small and compact bulb is used in decorative fixtures, track lighting, and small lamps. Part 4: Where Halogen Light Bulbs Are Used? - Common Uses Automotive Headlights: Halogen lighting offers reliable and affordable performance in headlights and foglights of motorbikes and cars.
