LED lighting technology allows you to save 86% of energy, with a life spam of up to 25 years, 2 years-guarantee. Discover what low energy lighting can do for you and for your pocket.
Thanks to the Led lighting, it is possible to reduce energy consumption without sacrificing the light quality. While the energy efficiency of a traditional bulb is 10% Led bulbs make use of up to 90% energy.

Colour temperature could be defined as the predominance of certain colours in WHITE lighting. In this way, white can be modified towards amber or towards blue. Colour temperature is measured in Kelvin and it is only applied to white lights. All other colours don’t have a colour temperature. For this reason, white lights, which have a predominance of amber, will be called warm lights and white lights, with a predominance of blue, will be called cool whites.
When we are in a room lit by a warm light, we feel like we are in a warm and comfortable environment. On the contrary, if we are in a room lit by cool lights, we feel like we are in a cool atmosphere.
The colour temperature is approximate since there are many factors which can produce changes. Unless you have a thermocolorimetre, you can’t know exactly the colour temperature of your luminaire.
Light source – Colour temperature (Kelvin)
A lumen is the measure of the total “amount” of visible light emitted by a source. The fact is that the lack of union between different manufacturers doesn’t allow the unification of criteria. However, theory tells us that a led can generate between 60 and 90 lumens. As a curious fact, the record of lumens generated by a led was 150 lm/w. If you want to know the lumens generated by a LED bulb, you can use this formula:
Real lumens = number of watts x 70
70 is an average value which corresponds to most bulbs in the market. Therefore, a 12W LED bulb would offer a light output of 840 lm. These bulbs could replace a 60W incandescent bulb. As you can see, they both generate the same quantity of light but thanks to the LED bulb, you will save energy.
One of the problems with LED lighting is its opening angle. That’s why, we should check its specifications and the recommended uses. The good news is that technology used in LED has improved a lot and now you can find LED bulbs that they alone can light a room.
If you buy LED bulbs whose opening angle is of 40º, you will obtain a more focused light, they would be perfect for lighting specific points like a painting, a glass cabinet etc. Therefore, if you want to buy a bulb for your bedroom you will need a bulb with an opening angle of 120º. However, if the room is bigger you will need to use more than one bulb.
The Kelvin indicates the type of colour which our bulb will have. Depending on the number, we will be able to have three types of light: warm white, neutral white and cool white. Each colour has a more or less practical application. Cool white is suitable to be placed in areas that require a white light such as the garage, the box room… Neutral white is suitable to be used in bathrooms, kitchens or any working place. Lastly, warm White is suitable to be placed in bedrooms, living rooms and so on because it offers an ambient lighting.
When shopping a bulb, you can consult the temperature. If the bulb is around 3000K, it will emit a warm white, if it is around 4500K, it will emit a neutral white and if it is around 5800K, it will emit a cool white. It is also interesting to look at the function of dimmers which are used to create an atmosphere by regulating the intensity.
We don’t have the same light installation at home. Some people use incandescent Bulbs, other people use halogen or fluorescent bulbs. It’s important that you revise your installation in order to know about which part we can reuse and which one we should change.
In the case of some halogen lamps, it is important to check the transformers. Firstly, because a transformer can support several LED bulbs since each LED bulb only consumes 10 or 12W. Secondly, it might be better to remove the transformers and to place a LED bulb which connects directly to a 220V network.
If you have dimmers it is very important that our LED bulb is compatible, to that end, the box usually indicates,DIMMABLE.
