A parking lot in Hong Kong is choosing between incandescent lamps or the newly developed LED light bulbs to renovate its lighting system of a total of 1,000 lamps for use of 12 hours daily. An incandescent lamp of 100 W costs around HK$9 each and is estimated to last for 1,000 hours of use whereas an LED light bulb with similar luminance for 15 W costs around HK$200 for the bulb and an extra HK$50 each for the installation but would work for 20,000 hours of operation. Discuss the financial feasibility of using either lighting technology with the electricity tariff being HK$1.21/kWh.
