Utility Costs and Usage

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 - $7.95 = $8.72 replacement savings

Step 3 determine energy usage over the life of this bulb

35 watts * 25000 hours / 1000 watts per kW = 875 kWh

4.1 watts * 25000 hours / 1000 watts per kW = 102.5 kWh

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

875 kWh - 102.5 kWh = 772.5 kWh lifetime savings

Step 5 find the lifetime energy cost savings

772.5 kWh * $0.118 = $91.16

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

$91.16 + $8.72 = $99.87 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% * 772.5 kWh lifetime savings = 56.3925 kWh yearly savings

7.30% * $99.87 lifetime savings = $7.29 yearly savings
