Our average electric bill is between 70 and 150 dollars depending on the month of the year.

We have gas stove, gas water heater, electric dryer, well pump, big ass flat TV, and all the typical electronics.

We have 8 light bulbs in basement they are old style 100 watt incandescent

Wanting to replace with 12 watt 60 equivalent LED bulbs I just checked today they are 26 dollars each.

Upstairs we have 13 little 25 watt incandescent bulbs in bathroom vanities, you can buy 2 watt to 25 watt LED they are 7.89 each

Upstairs we have 12 60 watt incandescent bulbs, I found that 12 watt LED bulbs will make 60 watts once again they 26 dollars each

8 of the bulbs have already been replaced with compact florescent bulbs, these are 13 watt bulbs, LED are 12 watt it does not make sense to replace them.

So to replace

8 at 26 equals $208

13 at 7.89 equals $102.57

12 at 26 equals $312

Sub Totals --- $622.57

Sales tax 37.36

Total equals --$659.93

If 25 % of the electric bill is for lights and the average monthly bill is $110 per month *.25 equals 27.5 dollars per month for lights.

The small bulbs are 2 watt to 25 watt so they use 8% of the power of the incandescent

The large bulbs are 12 w to 60 so they are 20 % of the power on the incandescent

Average would be 14% of previous consumption so my multiplier is .86 of $27.5 per month so $23.65 potential monthly savings,

$659.93 divided by $23.65 equals 27.90 months for cost return,

IS IT WORTH IT????
