Light-emitting diode (LED) light bulbs have become required in recent years, but do they
make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.45 and
lasts for 1,000 hours. A 7-watt LED, which provides the same light, costs $2.25 and lasts
for 40,000 hours. A kilowatt-hour of electricity costs $.121, which is about the national
average. A kilowatt-hour is 1,000 watts for 1 hour. If you require a 10 percent return and
use a light fixture 500 hours per year, what is the equivalent annual cost of each light
bulb? (A negative answer should be indicated by a minus sign. Do not round
intermediate calculations and round your answers to 2 decimal places, e.g.,32.16.)
