Re: LED lightbulbs now more widely available for consumers
If the wattage saved on one bulb is 50 watts, over 5 years, how much is that?
50W * 8 hours per day = 400W
400W * 365 days per year = 146,000W or 146 KW
In my area we have cheap power. It is about 11 cents/KW.
That works out to about $15 dollars a year.
I took a quick look online. The price to buy a bulb is running about $30 dollars.
So, it pays for itself in 2 years.
Everything after 2 years should be profit.
