Replace your old halogens with LED luminaires

There are several ways to replace the GX5,3 old halogens
There are many possibilities for replacing your old GX5,3 halogens ((they are usually built-in halogens installed in the 99% of the cases) for new led luminaries which allow you to save energy.

LED (Light Emitting Diode) is a light source which fits perfectly in an electrical circuit. As LEDs are light up thanks to the movement of electrons in a semiconductor material, LEDs cannot burn, cannot heat and they don’t use any dangerous substance.

Replace GX5,3 old halogens with GU10 LED luminaires

It’s the most advisable case. With this new installation, you will avoid using the transformer and you will achieve 3 important advantages:
  • GU10 LED bulbs don’t make any noise since they don’t need any current transformer. This effect is multiplied in rooms where there are several GX5,3 bulbs working at the same time.
  • GU10 LED bulbs plug directly into an electricity network and they consume just the energy needed by the bulb. The total consumption of a GX5,3 conventional bulb is the sum of its own consumption and the consumption of the current transformer (between 6 and 12W), in most cases the consumption of the current adaptor is higher than the consumption of the GX5,3 led bulb.
  • GU10 led bulbs emit no heat. GX5,3 bulbs emit their heat and the heat of the current adaptor.

LED energy savings

How much can I save with LED lighting?

In recent years, the electricity tariff has increased by more than 60%. Faced with this situation, it is important to have energy efficient appliances and devices. That’s why LED lighting has a great importance both at domestic and industrial level. The savings generated by a LED bulb compared to other bulbs not only depend on the watts consumed but also on the maintenance costs. The following table includes a comparison which represents the consumption in a household with ten 60W incandescent bulbs and the consumption of another household with ten 7W LED bulbs.

This table serves as a reference but, with these calculations, we see that a led bulb can save 1,6 Euros a month. If we multiply it by ten, we obtain a saving of 16 Euros a month, that is to say, 192 Euros a year. In offices or comercial premises, the investment will be recovered much sooner, the cost of the investment will be recovered in just 6 or 9 months.
LED lighting offers many advantages beyond economic saving. Led Bulbs provide with a uniform light which can be adapted to different uses, moreover, you can choose between different kind of colours and tones. To be honest, the first initial investment is high, that’s why it is advisable to gradually change your lighting system .

Characteristics of LED bulbs

Characteristics of LED bulbs
If you know the characteristics of LED Bulbs, you will chose the bulb that best meets your needs.

Power (W)

Electrical power is the result of dividing the energy consumed by the time it takes to be consumed. Its unit of measurement is watts or kilowatts, “W” or “kW”.

Colour temperature – Kelvin (K)

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)

Beam angle

The beam angle of a lamp is the angle at which light is emitted. The Beam angle is the angle between the two directions opposed to each other over the beam axis for which the luminous intensity is half that of the maximum luminous intensity. The viewing angle choice also affects the LED output intensity.

Number of LEDs

Another important aspect of a LED lamp is the quantity of diodes by which they are composed. In many cases, diodes are positioned along the surface of the tube and they are supported by a printed circuit board. The light distribution depends on the number of diodes. A tube with 400 diodes won’t have the same performance as tube with 270 diodes; the first one will achieve a more uniform light distribution.

How can I choose the correct lamp?

Choose a bulb that meets your needs. You have to consider the many aspects of the lamp such as its power in real lumens, its opening angle, its light temperature and your installation.

Light power

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.

Opening angle of light

The opening angle of light

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.

Colour temperature

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.

Cool white

Before buying

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.

Common questions about led lighting

What is a LED?

LED (Light Emitting Diode) is a light source which perfectly fits in an electric circuit. As LEDs light up thanks to the movement of electrons in a semiconductor material, LEDs don’t burn, don’t heat and don’t use dangerous substances.
