An LED, a.k.a Light Emitting Diode, is a semiconductor that releases light when an electric current passes through it. Electroluminescence is how LEDs generate light. There is less heat produced by this method, which is far more efficient.
How it works:
LEDs function through a complex interplay of materials and electrical energy. The core component is a semiconductor material, typically gallium nitride or indium gallium nitride, which serves as the foundation for light emission.
When an electric current is applied, electrons within the semiconductor are energized and recombined with holes, releasing energy in the form of photons. This process, known as electroluminescence, produces visible light. Crucially, the specific semiconductor material employed directly influences the color of the emitted light.
History:
The evolution of LED technology has been marked by significant advancements since its inception. Early LED prototypes in the 1960s were characterized by low intensity and limited to the red spectrum. However, subsequent breakthroughs in semiconductor technology enabled the development of brighter LEDs across a broader color range.
The creation of blue LEDs in the 1990s proved to be a pivotal moment, as it allowed for the production of white light through the combination of blue light and yellow phosphor. This innovation represented a substantial leap forward, propelling LEDs into mainstream applications and revolutionizing the lighting industry.

Halogen light is an incandescent light bulb that uses halogen gas inside a glass envelope. When compared to conventional incandescent bulbs, this gas helps to increase the filament's lifespan and boost light output.
How it works:
Halogens work very similarly. However,, they employ a sophisticated process to counteract the typical degradation of incandescent bulbs. A tungsten filament, when subjected to intense heat, undergoes a gradual evaporation, resulting in a darkening of the bulb's interior. However, the introduction of halogen gas into the bulb initiates a regenerative cycle.
As tungsten evaporates, it reacts with the halogen to form compounds which are then transported back to the filament. Upon reaching the filament's high temperature, these compounds decompose, redepositing the tungsten and preventing the bulb's dimming. This process significantly extends the bulb's lifespan and maintains light output.
Halogen lamps outperform incandescent bulbs in terms of efficiency and longevity due to their ability to recycle evaporated tungsten particles back to the filament. This process extends their lifespan to approximately 2,500 hours, compared to the 800-1,200 hours of standard incandescent bulbs.
Furthermore, halogen lamps can operate at higher temperatures, enabling the production of compact bulbs with significantly higher wattage, such as the small but powerful 250-300-watt halogen quartz lights.
History:
Halogen lights were developed as an improvement over traditional incandescent bulbs. Although the notion of using halogen gas to regenerate the filament was invented in the early twentieth century, practical halogen lamps did not become commercially available until the mid-twentieth century.
The addition of halogen gas to the bulb's atmosphere was a significant advancement, as it addressed the issue of filament evaporation, which shortened the lifespan and dimmed the light output of incandescent bulbs.

The lighting industry has witnessed a significant shift from traditional halogen bulbs to energy-efficient LED technology. This comparison between LED lights vs halogen lights delves into the key differences between these two lighting options, highlighting the advantages of each.
LEDs use electroluminescence, which uses semiconductors to transform electrical energy directly into light. This procedure is a great deal more efficient than the halogen light's incandescent method.
An incandescent filament covered in a glass envelope containing halogen gas is the source of light in halogen lamps. The filament heats up and emits light when power flows through it. By re-evaporating tungsten onto the filament, the halogen gas helps to extend its lifespan.
