A 100 W CFL light manufactured by Buyer’s Choice consumes 23 watts andhas an illumination rating of 1600 lumens and service life of 8000 hours andcosts $1.81. As an alternative, a generic 100 W incandescent light bulb costs$0.38 and produces 1500 lumens and has a service life of 750 hours. Let uscompare the performance of each light bulb by calculating the efficacy foreach light, and also estimating how much it would cost to run each light for 8hours per day for 220 days in a year. We will assume electricity costs 9 centsper kWh.For the Buyer’s Choice 100 W CFL light:
