LED Light Bulb Energy Usage Calculator
This calculator uses the average watt rating (100 Watts) for a LED Light Bulb. You can input your LED Light Bulb’s details to calculate the exact usage and cost of your device.
Hours used per day
Enter how many hours per day you estimate you run your LED Light Bulb. If it is less than one hour use a decimal. For example, 30 minutes would be .5 and 15 minutes would be .25.
Power used (Watts)
Input the wattage of your LED Light Bulb. If you are unsure enter the average wattage for a LED Light Bulb: 10.
Your energy rate
Enter the price per kilowatt-hour (kWh) you pay for electricity. If you are unsure you can use the average rate per kWh in the US (10 cents) or find the kWh rate in your area here.
How Much Electricity Does a LED Light Bulb Use?
The average 60-watt equivalent LED light bulbs uses .01 kWh of electricity per hour it’s on. In comparison the equivalent incandescent bulb .06 kWh of electricity per hour.
While the wattage of LED bulbs varies, it is always a more efficient option when it comes to lighting compared to its incandescent and CFL counterparts. Depending on the wattage of your bulb, LED bulbs are up to 75% more efficient than incandescent.
LED vs Incandescent Bulbs
Traditional incandescent light bulbs are far less efficient than LED bulbs. They require more energy to power, have a shorter lifespan, and quickly getting closer to the prices of LED bulbs thanks to the Energy Independence and Security Act of 2007. This act paved the way to phase out the use of incandescent bulbs.
LED vs CFL Bulbs
Compact Fluorescent (CFL) bulbs are more efficient than incandescent bulbs, but are less efficient than LEDs. CFLs require more wattage to produce the same amount of brightness (lumens) compared to LEDs.
For example, to produce 850 an LED only requires 7-10 watts whereas the CFL bulb will require 13-18 watts. Additionally, CFL bulbs do not last as long as LEDs. A CFL bulb last about 8,000 hours. A LED bulb lasts 25,000 hours or longer.
How Much Will I Save by Switching to LED Light Bulbs?
If your home is still using the old incandescent or CFL bulbs, switching to LED bulbs will pay for itself over time. Not only are LED bulbs more energy-efficient, but they also last significantly longer than both incandescent and CFL bulbs.
