How long do LED lights last?
Both CFL and LED light lamps will last longer than the incandescent model. When it comes to maintaining a CFL vs. LED lamp, however, experts again agree that you will likely need to replace the CFL model more frequently. In fact, the typical CFL has a lifespan of roughly 10 years. By comparison, an LED is expected to last at least 15 years, with some models exceeding 25 years. At roughly 1.5 (or more!) times the lifespan of a CFL, the LED will need to be replaced far less often.
What is a light bulb made of?
Years ago, the standard light bulb was made of a tungsten filament and inert gas surrounded by a glass enclosure. Known as an incandescent light bulb, a metal stem at the base of the glass structure allows an electrical current to trigger the filament and provide lighting. In 2014, however, incandescent bulbs over 40 watts were discontinued.
