LED bulbs, economic advantages

LED bulbs, short for Light Emitting Diode, are low-energy light bulbs that offer a longer life and better light quality than traditional incandescent bulbs.


They have become a popular choice in recent years for home lighting: they guarantee energy savings, since they need less energy to operate for the same output as incandescent technology. One might wonder whether they are a worthwhile long-term investment. Let us look more closely at the economic advantages compared with traditional incandescent bulbs, so that our readers can make an informed decision.

What is an LED bulb?

An LED (Light Emitting Diode) bulb is a low-energy lighting device. It contains a light-emitting diode, which converts electrical energy into visible light. LED bulbs are available in a variety of styles, from classic bulbs to spotlights, and new products appear every day, even including the option of using Wi-Fi to connect each individual bulb to the network via an app and control it, even by voice, with the best-known digital assistants.

What are the advantages of LED bulbs?

LED bulbs offer several advantages over incandescent bulbs. First of all, they consume less energy, since they use fewer watts to produce the same amount of light. They also last longer: up to 10 years. This means that consumers can also save on replacement costs.

Some models can produce a more intense light than incandescent bulbs. This is particularly useful in areas of the home that require brighter lighting, such as kitchens or bathrooms. LED bulbs also generally offer more even lighting, since their light does not have the dazzling effect that some incandescent bulbs have, and you can also choose different colours or a more or less “warm” light intensity.

How much can you save?

A 10-watt LED bulb can produce the same amount of light as a 60-watt incandescent bulb. This means that consumers can save up to 90% on energy costs in optimal conditions.

Another aspect is that, as mentioned, the life of LED bulbs is up to 10 times longer than that of incandescent bulbs. Obviously, this also means saving on replacement costs.

Comparison between LED bulbs and incandescent bulbs

To see how LED bulbs can be an option that saves both energy and money, let us look at an example (the figures are indicative and may change, but not by much).

A 60-watt incandescent bulb has an initial cost of about €1.50. Over the course of a year, this bulb consumes about 756 kWh of energy. On the other hand, a 10-watt LED bulb has an initial cost of about €3. Over the course of a year, it will use about 76 kWh of energy, at a cost about 10 times lower than the traditional incandescent bulb. As mentioned, these are indicative values: they also depend on the electrical system, the situation of use, electricity prices and the model of bulb.

How long do LED bulbs last?

LED bulbs can last up to 5, 10, 15 or 20 years. Their longevity depends on the product and the manufacturer. The costs will obviously vary. Naturally, a bulb that is switched on for one hour a day will last much longer than one that is switched on for 3 hours a day. Moreover, over the years LED bulbs undergo a certain degradation: so even if they still work, they may no longer be as effective.

Factors to consider when buying LED bulbs

When buying LED bulbs, there are a few factors to consider.
First of all, it is important to make sure you buy bulbs with the right power. If you buy an LED bulb with too much power, you will lose part of the benefit. It is also important to make sure that the LED bulbs are compatible with the lighting fittings already in your home. We suggest always consulting an electrician.


It is also important to buy from a reliable manufacturer. This will ensure that the bulbs are well made and meet the correct specifications. In addition, some suppliers offer guarantees on the life of the bulbs. This is a good “signal” that leads us to believe the bulbs will last for at least the years of the guarantee.
