The light-emitting diode (LED) is today’s most energy-efficient and rapidly-developing lighting technology. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting. LEDs use up to 90% less energy and last up to 25 times longer than incandescent bulbs. If you are still using
incandescent light bulbs, switching to energy-efficient is one of the fastest ways to cut your energy bill, for high-quality products with the greatest energy savings choose bulbs that have earned the ENERGY STAR.
With LEDs, you can light your home using the same amount of light for less money. When incandescent light bulbs were the only choice, wattage was the only number that mattered. Now to make the right choice when buying LEDs, you need to check the lumens. Watt is a measure of electrical power, a lumen is a measure of light brightness. If you are looking for an energy-efficent alternative to a 75-watt incandescentlight bulb, you should look for a 1,100 lumen LED light.
Today LEDs come in a variety of colors. The color of light is measured on a Kelvin (K) temperature scale. Higher K numbers mean the light appears cooler (blue) and lower K numbers mean the light is warmer. Warmer light most resembles incandescent lighting.
