More calculations:
Life time of fluorescent bulb: 10000 hours
Life time of incandescent bulb: 750 hours
10000 / 750 = rounds up to 14 bulbs. 14 incandescent bulbs are necessary to have the same life cycle as the fluorescent bulb.
Life cycle analysis of incandescent bulb:
19 bulbs ( 0.49 (cost of bulb) * 14 (replacement bulbs) + 0.1 (kWh) * 10000 (hours) * 0.08 ($/kWh -- price of electricity) )= $1650.34
Life cycle Analysis of fluorescent bulb:
13 bulbs (7.15 (cost of bulb) + 0.023 (kWh) * 10000 (hours) * 0.08 ($/kWh -- price of electricity) = $332.15
6(6.95 + 0.018 * 10000 * 0.08) = $128.10
Total: 332.15 + 128.10 = $460.25
