LED lighting is a more effective form of modern lighting technology. First, LED lights last longer than normal lights. For example, a normal light bulb lasts about 5,000 hours. LED light bulbs last 100,000 hours. Also, LED light bulbs change 80 percent of electricity into light. Normal bulbs only change 20 percent. In other words, LED lights use less electricity to produce more light. On the other hand, one disadvantage is that LED lights are more expensive than normal lights. However, they don't have to be changed every year and they use less energy. As a result, they are cheaper.
