LED Vs Halogen Lighting
LED (light-emitting diodes) is a semi-conductive form of light, meaning that an electrically conductive metal is used in concert with an insulator to create light energy. The metal is often copper along with glass as an insulator. The color of the plastic lens is often the reflected color of light, but this is not always the case. LEDs are frequently used as indicator lights, such as in traffic lights, but technological advances are increasing their potential functions.
Halogen light is a form of incandescent lighting with a small amount of a halogen element, such as iodine added. They produce a very wide spectrum of lighting, ranging from the ultraviolet to the infrared. Halogen bulbs are best used on equipment that requires very bright lighting. One of their most common uses is in automobile headlights. They are also commonly used as the light source for studios, stages, and in some household fixtures.
LED light has several advantages over halogen lights. They are more efficient and superior with regard to energy conservation. Halogen lights use electricity as a constant source of heat in order to light up. LED lights run electrical current between two electrodes, thus they give out more light per watt than incandescent lighting. Their efficiency is not affected by the shape or size of the fixture. LEDs can emit light of a particular color without using traditional filters, which also lowers energy costs. They light up extremely quickly with some LED lights achieving complete brightness in less than a microsecond. They are often the preferred source of lighting in systems that require a low failure rate. Unlike incandescent lights, which tend to burn out abruptly, LED lights slowly dim out over time. This gives operators the chance to change bulbs before they stop working.
Halogen lighting does have its share of advantages, as well. While LED lights are cost-efficient with regard to energy usage, they are still more expensive to buy than most other conventional forms of lighting. Halogen lights are more expensive than traditional incandescent lights, but more moderately priced than most LED bulbs. This is due to numerous components needed for manufacturing LED lights, including a sufficient heat sink. LED lights are very vulnerable to high temperatures, and may burn out far more quickly without one. They are more sensitive to voltage, as well. Halogen lights are better for reading and other tasks that require a brighter light for precision. LED lights are more likely to cause eye strain.
