LEDs are semiconducting devices that emit light by allowing electric current to flow through them. LED vs Halogen: Comparison Chart LED lamps They can suffer damage due to high voltage.LEDs are available in a variety of shapes and colours.They have been around since the 1900s in several electronic devices but quite recently they have been revolutionised as energy-saving and high-powered LEDs have made their way to our home and office light settings and introduced them to the mainstream business. Just as the CFLs or the Compact Fluorescent Lamps steadily replaced incandescent lamps, they are paving the way for LEDs. They are a good replacement for fluorescent and incandescent lamps as they have been standard in stereos, clocks and other electronic displays for a long time. LEDs or Light Emitting Diodes are simply semiconductors that emit light or flow when electric current flows through them. They emit a considerable amount of heat.They are similar to usual sunlight and can penetrate fog.The pin base of halogen bulbs restricts their use to certain fixtures that are specially designed for this bulb type. The quartz envelope allows the compact size as any kind of glass would melt being so close to the filament. But, with development in design, they are more efficient than the former and emit a higher amount of visible light than the incandescent lamps while reducing the emission of infrared light.Īlso, similar to an incandescent lamp, these lamps use a tungsten filament. They are similar to incandescent lamps in both construction and operation. Halogen lamps are a kind of incandescent lamp that use a filament surrounded by gas and held in a compact glass envelope.
