Compare old bulbs with LEDs and see yearly dollar savings.
The power drop from the bulb swap is multiplied by use time, days and the electricity rate to total the annual savings. LEDs use a fraction of the power of older bulbs, and the savings compound across every socket in the home.
LED Savings
Savings = (old watts - LED watts) x hours x 365 x rate / 1000
