Many people think of LEDs as expensive bulbs. What they do not know is it has many features on top of being a thrifty light source. For one, LEDs do less environmental harm than the common incandescent light bulb. According to research, this absence of mercury is one of the reasons why people need to support this product. It is not harmful to humans and it does not have harmful effects on the environment once thrown away. Consider some little known fun facts about LED lights.

  1. The first visible LED was invented in 1962 by Professor Nick Holonyak who then worked for General Electric
  2. LEDs are driven by DC (direct current), light bulbs are driven by AC (alternating current)
  3. LEDs don’t attract as many insects as other traditional light sources as they have very little UV content
  4. Good quality LEDs can easily have a lifetime which exceeds 50,000 hours
  5. More and more councils changing over their streetlights to LED versions, saving energy and increasing visibility.
  6. LEDs are not measured in watts. Instead, lumens are used to measure light output provided by LEDs. This is certainly one of the most interesting facts about LED lights.
  7. Blue LEDs can help keep food fresh – they have been proved to have a strong antibacterial effect on major foodborne pathogens, and are now being used in fridges.
  8. LEDs can last anywhere between 12 to 22 years. So can you imagine if you had a baby right now? He will be in high school or college before your LED goes off. In fact, LEDs last up to 25 times longer than the common light bulbs and CFLs. If you install an LED light in your baby’s room now, it will still be there by the time he is a grown up.
  9. From 2011 to 2012, global LED light sales increased by 22%. By 2030, it is estimated that LED lights will account for nearly 75% of all lighting on the market.
  10. In 2012, about 49 million LEDs were installed in the U.S. — saving about $675 million in annual energy costs. Switching entirely to LED lights over the next two decades could save the U.S. $250 billion in energy costs, reduce electricity consumption for lighting by nearly 50 percent and avoid 1,800 million metric tons of carbon emissions.
  11. About 95% of all LEDs are recyclable so nothing goes to waste.
