Why LEDs Trump Incandescent Bulbs Any Day of the Week

Light bulbs have truly come a long way in the 100+ years since being made popular by Thomas Edison. Yet despite the passage of many years, incandescent light bulbs, with their obsolete technology, can still be found in many households around the world. Fortunately, energy-saving LED light bulbs have emerged as a popular lighting option, taking the consumer market by storm. Although they generate light like any other artificial light source, they couldn’t be more different than incandescent bulbs. Whereas incandescent bulbs create light by literally burning a tungsten filament, LEDs generate a glow from electrons that move across semi-conductive materials. This means they don’t create the same kind of heat emitted by incandescent bulbs. But more importantly, they use much less electricity. 

Low temperatures One of the major issues with incandescent lights is that they generate high heat levels when in use—they get so hot they can cause burns when touched. To generate light, an incandescent bulb uses electricity to heat a tungsten wire to temperatures hot enough to create a glow—a process called incandescence. In a very bright room with several incandescent lights, you’d feel hot and uncomfortable. And if you happen to use incandescent bulbs in an air-conditioned room, the AC unit must work harder to fight hot temperatures. In contrast, LEDs are cool to the touch, even when used for several hours. Sure, they generate heat like any other electronic device, but they’re not as huge a fire hazard as incandescent bulbs. 

Long Life Spans Another advantage LED light bulbs have is their incredible life span. An LED can actually last as long as a transistor, which is around 30,000 hours. Compared to an incandescent light, which can only stay on for 1,500 hours, an LED can give you big savings. 

Energy Efficiency Since LED bulbs use a different method of producing light that doesn’t involve heat as a byproduct of light, this means they use a lot less electricity than incandescent bulbs. An LED uses a mere fraction of the power consumed by a 100-watt incandescent bulb, all while generating more light! Here are more reasons why incandescent bulbs are note a bargain at all.
