Light Emitting Diode (LED) and Compact Fluorescent Light (CFL) bulbs have been available for a number of years. These light bulbs use less power than an equivalent incandescent light bulb. Consider a 60 W Soft White bulb: .60 W-Incandescent - $0.50 per bulb - Life Hours = 1,200 • 13 W-CFL - $2 per bulb- Life Hours = 8,000 . 8.5 W-LED-$4 per bulb - Life Hours = 20,000 . Consider that your current home has 10 incandescent and 10 CFL bulbs installed. Assume for the sake of argument that they all are at the beginning of their life today and if one burnt out it would be replaced with the same type of bulb. Residential electricity costs about $0.12 per kilowatt hour (1 kilowatt hour is the equivalent of the power of 1 kilowatt being applied for 1 hour = 3600 kJ) and you expect to have every light on in your house an average of 5 hours a day each day. Provide a fully labeled Excel Chart/Table/Graph that shows the cost of replacing all your bulbs today with LEDs and using them until they burn out (20,000 life hours) compared to staying with the 10 incandescent and 10 CFLs over the same 20,000 hours. What is the total cost savings? Light Emitting Diode (LED) and Compact Fluorescent Light (CFL) bulbs have been available for a number of years.
