Light bulbs that use LED technology not only bring down your energy bills but are also more environmentally friendly when compared to incandescent bulbs and compact fluorescent lights (CFLs). Both the manufacture and use of LED bulbs causes less damage to the environment than the other two alternatives.
 
For starters, a 6-to-8-watt LED bulb, with a light output of 800 lumens, will last for 50,000 hours. In comparison, incandescent bulbs last 1,200 hours and consume 60 watts, while CFLs last for 8,000 hours and use 13-15 watts.
 
LED bulbs consume less power per unit (lumen) of light emitted. This reduces greenhouse emissions from power plants. Carbon dioxide emissions for LEDs are also low. Roughly, one LED bulb will minimize greenhouse gas emissions by almost half a ton.
 
The annual energy consumption for an LED bulb is around 30 times lower than for a corresponding incandescent bulb. According to the U.S. Department of Energy, lighting accounts for a fifth of the energy consumption in a U.S household. LED lights can bring lighting costs to 5 percent of the total electricity consumption in homes.
