One energy-efficient light bulb can last up to 20 times longer than an incandescent bulb using up 50 90% less energy. Consequently, not only is the better custodianship of the environment but it also literally impacts how much money is saved. Lighting fees, which account for roughly 10% of total household energy costs, decrease, as do 20% for commercial entities.
If the 110 million households and accompanying 23 million commercial businesses replaced simply one incandescent bulb with an energy-efficient LED, the energy savings would power a city of up to four million people or take the equivalent of 2.6 million cars off of our highways. The average home has 30 light bulb sockets and the average commercial site has 65.
Because LED lighting produces significantly less heat, it is much more efficient. LED light is 90% more efficient than incandescent and 50% more than CFL's, making LED light 10 times more efficient than incandescent bulbs. This explains why a 2 to 4 watt LED light creates the same amount of light as a 60 watt incandescent bulb.
