How do I calculate my LED energy savings?


CALCULATE LED ENERGY SAVING

Use the following calculations to determining energy saving for your LED bulbs. The higher the original wattage and longer time per day your lights are lit will exponentially increase  your savings. Don't forget to figure in the savings from not having to purchase new bulbs every year! Click to view bigger version

    1. Original Bulb Wattage – Replacement Bulb Wattage = Total Wattage Saved 
    2. Total Wattage Saved x Average Rated life/ 1000 = Total Kilowatt Hours Saved Over Bulb Life 
    3. Total Kilowatt Hours Saved Over Bulb Life x Energy Cost = Total $ Saved Over Bulb Life
LED SAVINGS EXAMPLE:
  1. 55W original wattage - 11W for LED bulb = 44W savings.
  2. 44W * 40,000 Hours/100 = 1760 KWH - Multiply your saved watts by your hours used to determine your kilowatt per hour. 
  3. 1760 KWH *$0.11/KWH = $193.60 - Finally multiply KWH my your local utility rate.
