It seems hard to justify spending $5.00 for an LED Ightbulb when an ordinary incandescent bud costs 50 C. To see if this makes sense, compare a 60 W incandescent but that lasts 1000 hours to a 10 W LED bulb that has a lifetime of 15,000 hours. Both bubs produce the same amount of visible light If lectricity costs $0.15/kWh, what is the total cost-purchase price plus energy-to get 15,000 hours of light from LED bulb?
