The Sylvania Super Saver 75 W light uses 20 watts, produces 1280 lumens, and costs $4.49. As an alternative a generic 75 W incandescent light bulb costs $0.40, produces 1200 lumens, and has a service life of 750 hours. Compare the performance of each light by calculating the efficacy for each light and estimate how much it would cost to run each light for 4 hours per day for 300 days in a year.
