**Compact Fluorescent Lamps, or commonly referred to as CFL's, are a simple, inexpensive and very effective way to lowering your energy costs. The average 60 watt incandescent light bulb is rated for 1000 hours of life, uses 60 watts of power and costs around $1.00. The average 60 watt equivalent CFL is rated for 8000 hours of life, uses 13 watts of power and costs around $4.00.**

**Let's do some math, calculating with a .11 per kwh cost, apples to apples. **

60 watt incandescent bulb

** ****Bulb cost $1.00**

**60 watts x 1000 hours = 60,000 watt hours / 1000 = 60 kwh.**

**60 kwh x .11 = $6.60 total energy usage cost. **

**$1.00 + $6.60 = $7.60 per 1000 hours.**

**$7.60 x 8 = $60.80 per 8000 hours. **

60 watt equivalent CFL

**Bulb cost $4.00**

**13 watts x 1000 hours = 13,000 watt hours / 1000 = 13 kwh.**

**13 kwh x .11 = $1.43 total energy usage cost.**

**$4.00 + $1.43 = $5.43 per first 1000 hours. **

**$4.00 + (8 x $1.43) = $15.44 per 8000 hours.**

**Using the above calculations, you would have to buy 8-60 watt incandescent bulbs at a total cost of $60.80 to equal the life of a 60 watt equivalent CFL with a total cost of $15.44. That one CFL would be saving you $45.36 over the cost of 8 conventional incandescent light bulbs. Just imagine if you were to replace 10 or 20 bulbs around your home. **
