The LED is the little bulb that could. A lighting giant in a tiny package, the lit LED bulb produces minimal heat, so a greater percentage of electricity goes into generating light rather than wasting energy. For this reason, cities across the nation that make the switch from incandescent to LED traffic lights save about 80% on electricity costs.
Because LEDs lack filaments, powered instead by the movement of electrons in a semiconductor material, they last 133 times longer than a standard incandescent, and approximately 10 times longer than a compact fluorescent bulb (CFL). An LED bulb can last ten years, or 10,000+ hours, and will dim at the end of their life rather than flicker or suddenly burn out, never leaving you unprepared in the dark. This incredibly hardy bulb resists vibration and shock, making it a reliable light source that saves you money in the long run by curtailing the need for replacement bulbs, despite being relatively expensive at the outset.
Within your home, use the LEDs focused light for task lighting. Unlike halogen lights and compact fluorescents, an LED's brightness is fixed and maximized in night lights, reading lamps and desk lamps. They come fun colors to enhance the mood you seek to create. White LEDs produce soft, clean light; blue is great for reading and reduced eyestrain. Red and green are also available.
