Slowly, but surely, incandescent lamps are disappearing from our living rooms. Energy-saving replacements such as LED lighting are taking their place. LEDs offer many more benefits than traditional lighting. LEDs are reliable, shock-resistant and have a long lifespan. But their greatest advantage is that they are extremely energy-efficient. Since LEDs barely get warm, much less energy is lost. To emit as much light as a traditional incandescent lamp, a LED lamp only needs a few watts.
