- How much electricity does a LED light bulb use?-

An LED lamp or LED light bulb is an electric light that produces light buy using light emitting diodes.

LED light bulbs have a much longer lifespan than incandescent or CFL light bulbs and they are more efficient. This is, the LED light bulbs have a lower electricity usage than the incandescent of CFL light bulbs.

Energy efficient bulbs

As shown as the picture above, the LED light bulbs are much more efficient than traditional light bulbs.

Under the same conditions, and when compared to a LED light bulb, an incandescent bulb will be using around 800% more electricity.

The table below show the power consumption of equivalent light bulbs. And by using the calculator we have provided on the next section, anyone should be able to estimate the electricity cost of running any bulb of any wattage.

Bulb lumens table

Additionally, this other table also provides valuable information than anyone should consider when deciding what light bulb type to purchase.

Electricity usage and cost calculator

The calculator below can be used to estimate the power and cost consumption of LED light bulbs over time. 

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


For example, if you have 8 LED light bulbs at home that:

  • Have a power rating of 7 Watts (W)
  • Are switched on 6 hours a day and 320 days per year
  • You are paying 0,217 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 23 euro (or dollars, or pounds, or…) per year in electricity costs to power up those 8 LED light bulbs.

Additional information

Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would like to learn more about them, have a look to this video that we have prepared for you.

All our videos can be found in YouTube, in both English and Spanish languages.

Also, please note that not only the electricity consumption must be taken in consideration when deciding what type of bulbs to install at home. Other factors like the bulb cost and the bulb lifespan must be taken in consideration.

The table below we are making a comparison between an incandescent 60 Watts bulbs and the equivalent CFL and LED bulbs. The purpose of the table is to give you a rough idea on the total cost over a 10 years period for the three types of bulbs.

If you are looking for saving electricity at home, have a look to this video where we provide some useful tips to reduce the electricity consumption and decrease the electricity bill.

Electricity conservation - Save and conserve energy

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.


For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32850 Kilowatt hour (kWh) per year. 

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

  • Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) we would collectively be saving nearly 6000 euro per year.
  •  To produce 32850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
Have a look to this page for more information about the amount of resources needed to produce electricity.

In any case it is clear that small energy savings do really count when looking into the bigger picture.

We hope that you have found the information on this page informative and of value.
