Installation Of Lighting On The Outside

Slate nature the more critical a house is, the more attention it requires. This is the case of single-family homes and chalets, which, to enjoy them, need some additional improvements. For example, the lighting of the exterior: your home will gain in security and decoration if you decide to install a system that gives light to both the facade of the house and the gardens.

Lighting an exterior can have different purposes: to be able to work in the shadows, create a comfortable environment, protect against intruders or merely avoid collisions with possible obstacles. The number of lights to be placed will already depend on each one, but we will always pass the cables under the ground or camouflaged in a wall.

Once chosen the models of lamps that best suit your style and your home, you have to get down working with the right tools.


Any outdoor light must be prepared for inclement weather. Therefore, in the case, we will find the letters IP followed by two numbers, which indicate the degree of protection of the lamps. The first number shows the resistance of the material to the powder. In this type of lights, you must mark at least 4 of a scale that goes up to 6.

The second number refers to the degree of impermeability of the light. The scale goes up to 7 (they can be submerged), but it cannot be less than 3, which means that it can withstand rain that is not very strong. From 4 the light can already withstand the force of a jet of water. We recommend that you do not choose an IP of the degree lower than 44.

On the other hand, lights and, in general, all devices with metallic elements must be protected from the risk of causing electric shocks. There are class II that have double insulation and do not require grounding. Class I lamps do need a ground connection (yellow / green cable). Also, it is advisable to take special precautions; that is why we recommend installing a 30 mA differential circuit breaker exclusively for connecting the installation of outdoor lights.

Facade lighting

We can choose two types of lamps:

Chalkboard nature The incandescent is the most ‘normal’ and produce ambient light. The intensity of the light will vary depending on the bulb that we put in the socket (75 or 100 watts). The choice of the model is entirely personal, but the most common are the balloons or lampposts.

Halogens produce a robust and concentrated beam of light to where they are focused. They also give off a lot of heat and get to burn, so we have to have some caution.

How high are they?

We will fix the lamps at a height higher than a person, never at eye level because it would dazzle us. If what we are looking for is to illuminate a large area and also to make a deterrent effect, we will elevate them more so that they cannot even access them.

We must avoid as long as we can pass the cables on the outside of the facade. Apart from being unsightly, it’s not at all safe. Once we know where we will place the light, we will make a hole in the wall with a stone drill with a diameter larger than that of the cables.

The connections

Making the electrical contacts is very simple. Having removed the light first, we will peel the ends of the cables and fix them to the lamp holder (we will never join the wires interlacing them with each other, we will use a terminal strip). It’s just about joining the same color threads. If the lamp has metallic elements, you must connect the ground wire (yellow/green).
