Light emitting diode (LEDs) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb cost $.35 and last for 1,000 hours. A 15-watt LED, which provides the same light, cost $2.90 and last 12,000 hours. A kilowatt hour of electricity cost $.111. A killowatt-hour 1,000 watts for 1 hour. However, electricity cost actually very quite a bit depending on location and user type. An industrial user in West Virginia pay $.04 per killowatt-hour whereas a residential user in Hawaii might par $.25. You require a return of 9% and use a light fixture 500 hours per year, What is the break-even point cost per killowatt-hur?
