A name brand 60 W CFL uses 13 watts, produces 801 lumens, and costs $4.49. As an alternative, a generic 60 W incandescent light bulb costs $0.40, produces 721 lumens, and has a service life of 750 hours. Compare the performance of each light by calculating the efficacy (in lumens/W) for each light and estimate how much it would cost to run each light for 4 hours per day for 285 days in a year. Assume electricity costs 9 cents per kWh. (Do not include the purchasing cost of the bulbs in your calculations.) CFL efficacy incandescent efficacy CFL cost incandescent cost $ $ lumens/W lumens/W
