Energy and Cost Savings of LEDs

The biggest benefit of LED lighting is its lifespan. An LED bulb will last approximately 50,000 hours --- six times longer than a CFL bulb. If the bulb is left on for eight hours per day, it will last over 17 years. During that lifespan, an LED bulb will use 300 kilowatt hours of electricity. At 20 cents per kilowatt hour, the lifetime electricity cost of an LED bulb is $60. To compare, you would need six CFLs to match the 50,000-hour lifespan of an LED. Those five CFLs would use 700 kilowatt hours of electricity, costing $240. The LED bulb saves 400 kilowatt hours of electricity compared to the CFL and 2,700 kilowatt hours compared to the incandescent bulb. This represents a cost savings of $80 over CFL bulbs and $640 over incandescent bulbs
