The LED bulb uses only 25 cents’ worth.
So the LED saves $1.23 per year.
Since it costs $20, it will take 16 years to recoup the cost in electricity savings.
At five hours a day, the incandescent uses $15.42 in electricity annually.

Do LED bulbs really last longer?
How long do LEDs last? Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years.
Is it better to leave LED lights on?
Fluorescent lights do take a small surge of power when turned on, but this is significantly smaller than the amount saved by turning them off. It used to be that starting them shortened their life, but again this is not significant. It’s always better to turn off modern lights if leaving for more than a minute.
Are LED lights cheaper to run?
The difference in wattage between traditional and LED bulbs. The large variance between an LED bulb and, say, a halogen bulb wattage is the reason LEDs are so much cheaper to run. This means that the LED spot uses 90% less electricity to run and therefore it costs 90% less.
