You probably noticed the increase use of LEDs for Christmas lighting. LEDs are beginning to be used in traditional applications for the home. EarthLED thinks that they can produce a LED “bulb” that will be equivalent to a 100 watt incandescent bulb for a suggested retail of $80. The LED will use 12 watts. An incandescent bulb sells for $1. The LED is expected to last 50,000 hours while an incandescent bulb will last 1000 hours. A kilowatt hour cost 8 cents. Prepare a cost analysis for the most used light bulb in a typical household which has an average use of 5 hours a day.
