A compact fluorescent lamp (CFL) is also know as compact fluorescent light or compact fluorescent tube.
The CFLs were designed to substitute the incandescent light bulbs and for that they were made compatible with standard bulb fixtures.
But how much electricity does a CFL light bulb use and, are they more energy efficient than the traditional incandescent light bulbs?
As shown as the picture above, the CFL light bulbs are much more efficient than traditional light bulbs but less efficient than LED light bulbs.
Under the same conditions, and when compared to a LED light bulb, a CFL light bulb will be using around 75% more electricity and an incandescent bulb will be using around 625% 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.
|250 lumens||25 W||4-9 W||2-3 W|
|450 lumens||40 W||9-13 W||4-5 W|
|800 lumens||60 W||13-15 W||6-10 W|
|1100 lumens||75 W||18-25 W||10-15 W|
|1600 lumens||100 W||23-30 W||15-20 W|
|2000 lumens||125 W||28-40 W||20-25 W|
|2600 lumens||150||34-55 W||25-28 W|
Additionally, this other table also provides valuable information than anyone should consider when deciding what light bulb type to purchase.
|Lifespan (approx.)||1200 h||8000 h||25000 h|
|Yearly Cost (approx.)||2,52 €/year||1,43 €/year||1,11 €/year|
The calculator below can be used to calculate the power and cost consumption of CFL 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 CFL light bulbs at home that:
You will be paying around 23 euro (or dollars, or pounds, or…) per year in electricity costs to power up those 8 CFL light bulbs.
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.
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:
In any case it is clear that small energy savings do really count when looking into the bigger picture.
