[10 Points) You have been asked to make a purchase recommendation for lighting for your plant's manufacturing floor. The level of light needed will require a quantity of 1,250 Type A luminaires; the same light level can be accomplished with a quantity of 1,500 Type B fixtures. The installed cost of the Type A fixture is $225; the installed cost of the Type B fixture is $350. The Type A fixture has a lamp life of one year at the expected usage; the type B fixture has a lamp life of 6 years. For both fixtures the re-lamp cost is 5% of the installed cost of the fixture. The Type B fixture has an input power of 80 Watts; the Type A fixture requires 225% more input power. The lighting will be used for two work shifts, that is, 16 hours per day for six days per week with a 52 week work year. Energy is priced at a cost of $0.075/kWh; the cost of money is 8% per year. If the project is to be maintained for 12 years, including a re-lamping at the end of the project and assuming no end-of-life salvage value for either fixture type, what is the best choice for the factory floor lighting? Show all your work and clearly explain any assumptions. [10 Points) You have been asked to make a purchase recommendation for lighting for your plant's manufacturing floor.
