A faculty administration wants to change all fluorescent lights in rooms, labs, and classrooms. There are 250 lambs. A regular bulb is 5 TL and a LED bulb is 45 TL. A regular bulb consumes 40 Watts electricity whereas a LED bulb consumes 6 Watts. If electricity price is 0.80 TL per kilowatt-hour, how many days later will LED bulbs be more economical. Assume average working time (of all bulbs) is 6 hours. Note that the time for average life of the bulbs is 3 years.
Compact fluorescent tubes cost $15 each and have an estimated life span of 8,000 hours. These tubes consume 20 W of power, but produce illumination equivalent to that of 75 W incandescent bulbs. These cost $3.75 each and have an estimated life span of 1,200 hours. If a home has, on average, six 75W incandescent bulbs on constantly and energy costs $0.2875 per kilowatt-hour, how much money will a consumer save each year by installing fluorescent tubes instead?
