Step 1 find the number of INC bulbs needed over this bulb's lifetime

25000 / 750 = 33.3333

Step 2 determine the cost of replacement INC bulbs and the difference with this bulb's cost

33.3333 * $0.50 = $16.67 cost of replacing the INC bulb

$16.67 - $2.95 = $13.72 replacement savings

Step 3 determine energy usage over the life of this bulb

60 watts * 25000 hours / 1000 watts per kW = 1500 kWh

9 watts * 25000 hours / 1000 watts per kW = 225 kWh

Step 4 subtract to find the difference in energy usage between the bulbs

1500 kWh - 225 kWh = 1275 kWh lifetime savings

Step 5 find the lifetime energy cost savings

1275 kWh * $0.118 = $150.45

Step 6 combine energy savings with replacement cost savings to find total lifetime savings

$150.45 + $13.72 = $164.17 total lifetime savings

Step 7 find savings per year

5 hours per day * 365 days per year = 1825 hours per year

1825 hours per year / 25000 lifetime hours = 7.30% of bulb life used per year

7.30% * 1275 kWh lifetime savings = 93.075 kWh yearly savings

7.30% * $164.17 lifetime savings = $11.98 yearly savings
