There are fewer & fewer incandescent bulbs available and soon to be only specialty incandescent made... They are inefficient and short lived...
Any time you use Less amperage to do the same thing, your energy use Will go down... any time your usage goes down your billing will also go down... But the bill you get for that usage may not go down ... there are all kinds of add on charges, fees and taxes that the utility companies periodically get to add to the billing... If you do not seek ways to reduce your consumption, your bill will really grow ... :smile:KennyV
BTW what are you paying per kilowatt where you are located..?
