There are more than 30 billion light bulbs in the world, and 10 billion must be manufactured each year to replace those that no longer work.
And these are all light bulbs that work every day and use electricity.
We then understand the importance of choosing low-consumption references in order to preserve the resources that are available on the planet.
Like household appliances, light bulbs will display a more or less substantial energy consumption from one model to another.
So for your home, choose those that are energy efficient.
In this guide, you will find out how to recognize a low-consumption light bulb and we will also look at the case of LEDs.

How to recognize a low consumption light bulb?
In order to know if the bulb you want to buy is a low-energy model, you have to look at its energy label.
The latter classifies household appliances, but also light bulbs, from A to G. It is now mandatory on packaging in order to allow consumers to find their way around.
To choose a bulb with the lowest possible consumption, choose those with the letter A or B. You can also consider the power of the bulb, which is expressed in watts.
The higher the number of watts, the greater the consumption.
Finally, consider the luminous flux.
The latter is expressed in quantity of lumens per watt consumed.
The higher the number of lumens per watt, the more efficient the bulb is in terms of saving energy.
Do LED bulbs consume a lot?
Now let's talk about LED bulbs.
This technology is not new since the first LED bulbs were born in Russia in 1927. And if they are still so popular, it is not without reason.
The first advantage of this type of bulb is its very low energy consumption.
Indeed, an LED bulb will consume between 60 and 90% less electricity than a conventional bulb.
The light output is therefore much higher, and the electricity bills much lower.
In addition, while LED bulbs are generally more expensive to purchase, they have a much longer lifespan than conventional ones.
An LED bulb can shine for 50,000 hours, while a conventional model will work between 1000 and 2000 hours.
A really big difference.
Another point, an LED bulb displays an almost non-existent light warm-up time.
This means that as soon as you turn on your lamp, the brightness is at 100% output.
There is no heat or infrared light emission with an LED bulb.
In addition, it does not contain mercury and does not emit any parasitic noises or crackling which can be quite unpleasant.
To recognize an LED bulb, you can already note the absence of a small filament, unlike incandescent bulbs.
They are also often the ones who let go when the classic light bulb stops working.
With an LED bulb, the ratio of lumens emitted per watt consumed is significantly higher than that of a conventional bulb.
It can easily reach 100 lumens per watt, while it is more around 10 lumens per watt for conventional models.
This is why you can see mentions of the type 9W = 60 W on the packaging of LED bulbs.
This shows that with a much lower consumption the lighting remains the same.
To go further in understanding the labels of LED bulbs, let's talk about the color of the light emitted.
It is given by the temperature in degrees Kelvin).
If the temperature is between 2300 and 3500 K, you get quite warm illumination through orange to yellow light.
If you exceed 6000 K, the light will be whiter, even blue, and therefore much colder.
