Sorry Thomas Edison, Here's Why LEDs Are the Better Bulb

Because of the “New Light Bulb Law,” Jan. 1 of this year marked the beginning of the end for America’s most popular source of light — the incandescent bulb. Even though these bulbs have lit homes around the world since the late 1800s, energy-inefficient incandescents are being phased out in favor of new types of bulbs that bring more light for less power. Taking their place is the LED (short for light emitting diode). When LEDs were first introduced, they were primarily used for traffic signals. Now, we see them in lamps, flashlights, cell phone screens, computers, automobile headlights and more.
