A set of six long-life light bulbs costs $15.95. Each bulb is rated for 20,000 hours of service and 60 watts of output. The electrical efficiency of each bulb is 85%. The alternative to these long-life bulbs is a standard 60 watt bulb that costs 60 cents ($0.60), is rated for 1000 hours of service and is 95% efficient.
a) If the cost of electricity is 10 cent ($0.10) per kilowatt-hour, which type of bulb is better when lighting is per year. Assume end-of-year cash-flow convention.
b) what factors besides cost may dictate the choice of the better light bulb ??
