CFL to LED wattage
This post aims to be an easy and practical guide about light technologies and their equivalences in power.
Sometimes, it is hard to choose the right relationship when replacing our old lights for newer technology ones, concretely when we try to change an energy-saving light bulb to a LED one. Well, we hope this short guide will help us out from now on.
Hereby you will find a couple of tables which gather the equivalences that you can follow in order to guide yourself when choosing your bulbs or lamps’ replacements. We are comparing of course LED technology, since we are in the LED’s era but, at the end, you will be able to find a summary with all technologies we could think of together.
Do these tables mean you can not choose for a W up or down from the examples being shown? NO. These tables are nothing more than a guide to help ourselves to understand the equivalences but this does not mean that a W up or down would be a wrong choice at all.
CFL light bulbs vs LED
This equivalence is often the most difficult and tricky point to understand since, it is usually not written in the lights’ boxes or prospects. We have loved CFL and their efficiency for many years already and they have saved us tons of energy and money but, the LED era is here and that means more savings and no toxic substances around us. LED lights are capable of saving you around a 40% of energy when changing from CFL lights.
|CFL Light Bulb Wattage||LED Equivalent Wattage|
|22 Watt||12 Watt|
|15 Watt||9 Watt|
|9 Watt||5.5 Watt|
|5 Watt||2 Watt|
All technologies vs LED
Since we were writing about equivalences when replacing older technologies for LED, we were thinking… Why not to make a small table involving all other technologies? This way we hope you can get a quick overview of how much energy is possible to save with LED. This technology is one of the easiest ways to save a lot of energy and money for every house, office and warehouse or any other space which needs lights in the World.
|Incandescent Light Wattage||Halogen Light Wattage||CFL Light Bulb Wattage||Sodium Light Wattage||Fluorescent Tube Wattage||LED Wattage|
|-||-||-||200 Wat||-||100 Watt|
|-||-||-||150 Watt||-||60 Watt|
|-||-||-||70 Watt||-||30 Watt|
|-||-||-||-||70 Watt||24 Watt|
|150 Watt||-||33 Watt||-||58 Watt||22 Watt|
|-||100 Watt||28 Watt||-||36 Watt||18 Watt|
|-||-||25 Watt||-||-||13 Watt|
|100 Watt||-||22 Watt||-||-||12 Watt|
|-||75 Watt||18 Watt||-||-||11 Watt|
|-||60 Watt||16 Wat||-||-||10 Watt|
|75 Watt||50 Watt||15 Watt||-||20 Watt||9 Watt|
|-||40 Watt||-||-||-||8 Watt|
|60 Watt||-||13 Watt||-||-||7.5 Watt|
|50 Watt||30 Watt||11 Watt||-||-||6 Watt|
|40 Watt||-||9 Watt||-||-||5.5 Watt|
|30 Watt||-||8 Watt||-||-||4 Wat|
|25 Watt||-||7 Watt||-||-||3 Watt|
|-||-||5 Watt||-||-||2 Watt|
|9 Watt||-||-||-||-||1 Watt|
Now it should be clear to everyone!
Let's see now two examples of how to use this tables:
For instance, if the bulb we need to replace is a 75W incandescent and we want to replace it for a halogen kind of bulb, we would have to choose a 50W one (or the closest to 50W we can find) in order to ensure maximum savings without losing the amount of light. However, if the bulb we want to replace is a low-consumption or energy-saver (CFL) of 25W and we want to replace it for a LED technology one, we could simply choose a 13W LED bulb and we will be all set. Easy, right?
Again, please remember these tables are no more than a guide to help ourselves to understand the equivalences but this does not mean that a W up or down would be a wrong choice.
Please bear in mind that here we are only referring to the bulbs’ power, not the caps or colors which you must also pay attention to when choosing your new bulb.
We hope this guide helped you out!
