As a rule, LED bulbs use 90% less electricity than standard bulbs. They have an unparalleled even spectrum of light and have a lifespan beyond ten years.
LED's provide us the most efficient way to save energy and conserve our natural resources. If LED's were implemented right now universally, we would never need to build another power plant. LED would actually eliminate the need for over 30 power plants.
Just changing your lighting to LED alone, will reduce your energy bill and C02 footprint by over 50%. LED lighting has the potential to eliminate over 115 million metric tons of carbon emissions. Such incredible benefits from a small package.
